Success

Success percentage - this is the percentage of time the controller has been connected to

Hydrawise. We measure this over a 6-hour time frame. 100% means it was always

connected, 80% means that for 20% of the time it was not connected.

A low success percentage will indicate a poor wireless connection between the controller

and your access point.

To improve your wireless signal strength you could try the following –

Move the controller closer to your wireless router.

Remove any obstacles in a direct line of sight between the controller and your wireless

router such as metal items (metal is an extremely good isolator for WiFi signals).

Move your wireless router closer to the controller.

Install a higher gain antenna on your wireless router.

Use Ethernet to a location closer to the controller and install a new wireless router.

Consider a WiFi repeater/extender between your wireless router and the Hydrawise

controller to boost the signal strength.

Consider moving the controller away from potential sources of interference, including

microwave ovens, nearby base stations using adjacent channels or cordless

telephones operating in the 2.4GHz range (you could also change the channel your

phone uses).

Note that the Hydrawise unit is designed to work in poor wireless environments. However, if

you wish to manually run or stop a zone and the wireless signal is down then these actions

will fail.

Offline

If the controller loses internet for more than 24 hours you’ll receive a notification email.

The controller will go into an offline mode. In offline mode, your controller won’t be able to

access local weather conditions such as rainfall or evaporation and will revert to a pre-

defined program.

For Smart Watering zones, the controller will adjust each zone’s watering length based

on your offline watering budget and will water at each zone’s configured peak watering

frequency.

For Time Based Watering zones, the controller will adjust each zone’s watering length

based on your offline watering budget and will water at each zone’s configured

watering frequency.

For more information on Smart and Time Based Watering, see “Configuring Irrigation

Zones” [2].

Note that Cycle & Soak is not supported in Offline Mode and each zone will water for

its full watering length without pausing.

The controller will only water at your configured Program Start Times.

Saving Settings

The controller does not need a battery, all settings are saved in a non-volatile RAM

(memory).

Controller - Blank Display

First, make sure there is power to the controller's outlet. Use a test lamp or any other

110VAC device to determine if there is voltage at the outlet. If there isn’t power, or if you

have a controller that is hard wired, check the circuit breaker at the main breaker box.

Caution: High voltage testing on the transformers primary power side should only be done

by a professional electrician or irrigation contractor.

Checking Transformer Voltage

If you have power at the outlet, the next thing to check is the transformer output. Use a voltmeter to check the

voltage either on the two transformer wires or at the two AC screw terminals on the controller. The transformer

should have an output in the range of 24VAC to 28VAC.

If the wall outlet has 110VAC and the transformer has no voltage output, you need to

replace the transformer.

Cycle Controller Power

If you have voltage at both the wall outlet and the transformer output and you still have a

blank display, try cycling the power on the controller. To cycle the power on the

controller:.

1. Remove power by unplugging the transformer from the wall outlet or by turning off the

circuit at the breaker box.

2. Wait a few minutes.

3. Plug the controller transformer back into the electrical receptacle, or turn the breaker

panel switch back on.

Note: If this doesn't restore the display, the controller will need to be replaced.

No Zones Running

In this article, we will cover the most common reasons why your sprinklers are not running.

Topics include the following:

Testing water supply

Testing controller voltage

Test Wi-Fi on the controller

Test Water Supply

The water could be been shut off to the zone valves. Go to the zone valve and give the

solenoid (where the wires are connected) a ½-turn counterclockwise. If the valves have

water, the sprinklers will come on even without the controller. See the illustration below for

activating the valve solenoid manually:

If the sprinklers turn on by manually twisting the solenoid, follow the next step to check for

proper voltage.

Test Controller Voltage

To confirm proper voltage is getting to the valves using a voltmeter, follow the steps below:

1. From the Home screen, navigate to the Zone Summary screen by

pressing Zones.

From the Zone Summary screen, touch the zone you wish to view. The

Zone Summary screen shows the status of six zones at a time. To view

the next or previous group of zones, use the Next and Previous buttons.

The current range of zones that you are viewing is indicated at the top of

the screen.

From the Zone Status screen, you can manually start a zone using the

Run Now button. When started, the zone will run for the zone’s default

configured run length. This can be overridden by clicking on Run Time

prior to manually starting the zone. When a zone is running, the Run Now

button will change to Stop. This allows you to stop a running zone.

2. Use a volt meter to confirm there is 25–28 VAC at the screw terminals marked "C" and

the corresponding station screw terminal (e.g., "C" and "2").

3. Next, go to the valve in question and check the same two wires connected to the valve

for the same voltage.

4. If there is no voltage or low voltage at the valve, you may have a damaged wire or bad

connection from the controller.

5. If you have necessary voltage (25–28 VAC) at the valve then the solenoid may need to

be replaced.

If you need a new solenoid for the valve, Hunter makes our products and replacement

parts available through our network of authorized distributors. Click on the following link to

find an Authorized Hunter Distributor in your area: Distributor Locator [10]

Test Wi-Fi on the Controller

If the irrigation system did not water on the scheduled day, you may have a cancellation

caused by a sensor or a water trigger. Refer to this article [11] if this is the case.

If your controller loses internet connectivity for more than one day, we'll send you an email

notification. During this time, your controller will run the last synced schedule in offline

mode.

NOTE: Without internet connectivity, your controller won't be able to automatically modify its watering schedule

based on weather forecasts.

If the last synced schedule was for the controller to remain off, follow the steps below to

reestablish the Wi-Fi connection.

1. Check that your wireless router and controller are powered on.

2. Signal Strength check: Settings > Wireless > Wireless Name > Select Network >

Read strength (High recommended for optimal functionality).

3. Reboot Controller: Settings > Config > Reboot Controller > Check Server Status

4. Factory Default: Settings > Config > Factory Default > Erase Config > Connection

Wizard > Check Server Status

5. Reset Modem/Router: Unplug for 15–20 seconds. Then plug back three times >

Check Server Status. This will refresh the connection to an extender if you have one

installed.

6. Reset Extender: Reset the extender as well to refresh IP settings.

7. Check Network Settings: The following Wi-Fi requirements apply to your Hunter

Hydrawise-ready controller.

Hunter HC controller is 802.11 b/g

Hunter Pro-HC controller is 802.11 b/g/n

Hunter HPC controller is 802.11 b/g/n

Bandwidth: 2.4 GHz only; not compatible with 5 GHz

Router channel: Set between 1–11

Guest networks/networks with portal page login: Not compatible

Mac address (if needed):

HC: Enter 001e followed by serial number (e.g., 001e05fb90ce)

HCC/HPC/PROHC: Enter f8f0 followed by serial number (e.g., f8f005fb90ce)

8. Testing with hotspot: Depending on your smartphone, use either guide below:

Apple hotspot [12]

Android hotspot [13]

Check server status: This test will tell you if the controller is working properly and if you

need to install an extender for better connection.

Wi-Fi Extender Note: You can try to connect to the extender via hotspot. If you have

connection issues here, you not getting an internet connection from the source.

If controller will not connect to the hotspot, email the Support Team:

Hydrawise Email Support [14]

Sprinklers Running with the

Controller Off or Unplugged

There are two reasons why sprinklers would continue to run with the controller Off or

Unplugged:

It's possible your valves were opened manually. Locate your valve box(es) and turn the

solenoid(s) clockwise until snug. The solenoid is located on top of the valve and looks

like a cylinder with two wires protruding out of it.

It's also possible that debris in the valve is causing the diaphragm to remain open.

To fix this problem:

1. Disassemble the valve.

2. Rinse all parts with clean water.

3. Reassemble the valve.

If you cannot locate your valves, contact the contractor who installed the system.

iOS and Android App Support

Policy

The Hunter Hydrawise app’s general policy is to support Android and iOS version for as

long as the manufacturer (ie. Google or Apple) supports their operating system version.

It is important to use an Android or iOS version that is supported by Apple or Google to

ensure you have the manufacturer’s latest security updates to protect your data.

As of July 2019, Google officially supports Android 7.0 (Nougat) and above. Apple officially

supports iOS versions 12.3 and above.

While we do our best to maintain support for older versions, changes in technology mean

that sometimes it is not possible to add features to our apps whilst maintaining backward

compatibility with unsupported versions of Android or iOS.

While not supported, we do have customers using older versions of Android (eg. Android

5.0) and iOS (eg. iOS 10.0) without issues.

If your app does not work with your unsupported version of Android or iOS, it may be

possible to use your Hydrawise system via the web browser (www.hydrawise.com [20]) in the

older device.

Hydrawise Controller Efficiency

LEED

Controller Efficiency (CE) is a value that helps determine the amount of potential landscape

water savings for a LEED-certified project. CE is calculated as the percentage of potential

water savings delivered from a weather or moisture-based irrigation controller subtracted

from one (1), as reflected in the following equation: CE = 1 – (percent savings).

Hunter Industries offers three solutions that meet or exceed USGBC LEED requirements:

Solar Sync® paired with any AC-powered Hunter controller

Soil-Clik® paired with any AC-powered Hunter controller

Hydrawise™ software paired with a Hunter HC, Pro-HC, X2 with WAND, HPC, and

HCC controllers.

Since there are many variables that influence the actual percentage of water savings

delivered from a weather or moisture-based irrigation controller, it is difficult to place a

value on any specific controller. However, through in-house testing, third-party testing, and

field audits, Hunter has determined that water savings delivered from the Solar Sync, Soil-

Clik, and Hydrawise solutions typically range from 20% to 40%. This would translate to a

CE of 0.6 to 0.8. Please contact your local Hunter sales representative to learn about

additional ways to save water for your LEED-certified projects.

Setting up a Controller in Offline

Mode

Offline programming will allow your controller to run without any internet access like a

traditional irrigation controller. Hydrawise controllers have two different modes that will run

in offline mode.

Modes Controller Models

Standard Mode HPC, HCC, PRO-HC, and X2

Advanced Mode HPC, HCC, PRO-HC, and HC

Standard offline programming will allow the controller to run like our traditional controllers

the X-core and the Pro-C models. Each of the six programs (a-f) allows you to start each

program up to four times a day, set run lengths and set specific days to water.

Advanced offline programming will allow the controller to run independently for each

zone(station). Each zone (station) can have up to four start times with their individual run

times.

Offline Adjustments - Watering

with no Internet

If your controller loses internet connectivity for more than one day, we'll send you an email

notification. During this time, your controller will run the last synced schedule in offline

mode.

Offline watering adjustments apply when your controller is not connected to the internet

after 30 minutes.

You can access this setting from the Controller Settings tab on your home dashboard.

In offline mode, the controller will set watering times based on watering adjustments set up

beforehand.

If the next irrigation event for a zone was scheduled for Saturday, offline mode for that zone

would start after the irrigation event on Saturday if the controller didn’t have the internet. If

there are no irrigation events scheduled in the controller when it loses the internet, offline

mode will start 30 minutes after the controller loses internet.

NOTE: Without internet connectivity, your controller won't be able to automatically modify

its watering schedule based on weather forecasts.

CONTROLLER SCREENSHOTS:

HC - Older Install Instructions

Controller Location

The Hydrawise controller is designed for installation in a protected location.

IMPORTANT: The chosen location must have Wi-Fi coverage. Wi-Fi coverage can be easily checked using an

iPhone or smartphone that has Wi-Fi connectivity, or on the Hydrawise unit itself (signal strength is shown when

you select a wireless name).

Cable Entry

The controller has two cable entry options: from the rear of the case, or via a conduit from

the bottom of the controller.

Entry from the rear of

controller

Using a sharp knife, remove the two cutouts on the rear of the controller as

indicated on the diagram in label 1.

Entry via 3/4 inch conduit

Using a sharp knife, cut around the semicircular line on the controller as

indicated on the diagram in label 2. Cut around the matching line on the blue

controller wiring cover.

Mounting the Controller

1. Using a 3/16-inch diameter drill bit, drill a hole to a depth of 1 inch (25 mm).

2. Insert plastic anchor so it is flush with the surface of the wall.

3. Screw 1-inch screw into plastic anchor, leaving the head protruding about 1/8 inch.

4. Slide the controller case over the screw head.

5. Mark your second mounting point (see label 3 in the diagram). Then remove the

controller, drill a hole, and insert a plastic anchor. Finally, slide the controller case over

the first screw head and screw it into place.

Connecting Solenoid Valves

Depending on the model you purchased, your controller has either 6 or 12 zones. For

convenience, there are three common wiring points, and any or all of them can be used.

Refer to the diagram below when connecting your solenoid valves to the controller.

Solenoid Valve Wiring

1. Take one wire from each solenoid. Twist the wires together and connect to the

COMMON (usually black) wire of your multicore irrigation cable. Hydrawise

recommends that all connections be sealed against moisture for long-term reliability.

2. Connect each of the other individual solenoid wires to a different wire in the multicore

cable and seal. Record zones against wire color for later reference.

3. Connect the common wire from the multi-strand cable (usually white) to any of the

three terminals on the controller marked COMMON.

4. Connect each of the other solenoid wires to one of the zone inputs.

5. If a master valve (sometimes labeled as MV on other controllers) is installed, this can

be connected to any spare zone, as any of the zones can be assigned as a master

valve output. The configuration of the master valve in the Hydrawise app is required.

6. Click the blue wiring cover into place to seal the controller and protect the wiring.

Connecting the Plug Pack

1. Use the plug pack supplied and connect the wires to the red AC terminal blocks on the

unit marked as 24V. The polarity of the wiring is not important.

2. Turn the power on. The power indicator will light up (see label 4 on the previous

diagram).

Connecting Sensors or Flow Meters (Optional)

Hydrawise supports most open/close contact sensor types, such as standard rain sensors

and soil moisture sensors.

1. Connect one sensor wire to COMMON on the controller.

2. Connect the Normally Closed or Normally Open wire from the sensor to SENSOR1 or

SENSOR2 on the controller, and configure in the Hydrawise app.

For full details, refer to the instructions provided with your sensor or flow meter. Instructions

for configuring the controller for a sensor are available here [30].

Troubleshooting Zone Issues

Try running a zone from the controller’s touch screen. If it works from the controller and

doesn’t work from the app, check that you have linked your controller’s serial number

to your account (see the previous section for details) and check your controller’s

wireless status.

If your old controller had a master valve (sometimes referred to as MV), you must

configure a master valve in the app and wire it to a spare zone on the controller.

Detailed instructions can be found on the Hydrawise website.

Check that your wiring is correct. If no zones start, check that your COMMON wire is

correctly cabled.

Lightning Transformers with

Controllers

Hydrawise controllers are capable of operating lighting transformers equipped with the

PXSYNC interface box. A commonly used transformer with the PXSYNC is the PX or EX

Transformer. We also offer a DX Transformer that can be controlled from a irrigation

controller via the 24 volt EXTERNAL connection built inside the controller.

Connect wires from the first PXSYNC or external ports inside the DX box to a station

output number (and the Common) on the Hydrawise controller.

PRO-C with PX SYNC Example

Important Pump/Master Valve notes:

Controller P/MV Terminal Output

If a pump or master valve is in use,

the lighting transformer should not

be used in conjunction with

irrigation controller.

Single station output will operate

one at a time. Irrigation must not be

programmed for duration of the

lighting schedule.

HCC

If using PUMP or master valve, this

station output must be set to OFF in

the programming.

Two station outputs will operate at

a time. Any two programs will run

simultaneously (lighting program

and irrigation program).

HPC- WRCLIK and HC Flow Meter

In the event you will need to install a flow meter and a rain sensor on the HPC controller,

please use the following instructions. The HPC controller utilizes a single SEN output so

these steps are necessary to make this work. For correct field wiring of the flow meter,

please reference the article here. [31]

NOTE: The software will only recognize the flow meter for this type of installation. The

Wireless Rain Clik will still shut down system after a rain event, but this will not reflect

anywhere in the software. The reports will not show ANY data for the rain events.

IMPORTANT: You will see alerts for underflow from the flow meter since the system will

continue to run even with the common circuit interrupted by the rain event. These alerts will

have to be ignored for this type of application. For more details on alerts, please view this

article here. [32]

Flow Meter - Reading Meter

The Hydrawise flow meters come in a US Gallon reading for domestic and metric reading

called M³ (Meters Cubed 1000 Liters) for international. Conversion rate for metric meters is

3.78 Liters to 1 US Gallon if required.

See example of meter reading below in US gallons:

Fig. 1 X100 8100 Gallons

Fig. 2 X10 814X.XX Gallons

Fig. 3 X1 8142.XX Gallons

Fig. 4 X0.1 8142.4X Gallons

Fig. 5 X0.01 8142.46 Gallons Total

Fig. 6 Size meter 1"

Fig. 7 Flow Indicator Wheel spins when water is flowing.

We have a flow that has gone through the meter of 8,142.46 gallons.

See example of meter reading below in Litres:

Fig. 1 8,000 Litres

Fig. 2 8,200 Litres

Fig. 3 8,220 Litres

Fig. 4 8,224 Litres

Fig. 5 8,224.7 Litres Total

Fig. 6 Wheel spins when water is flowing.

So we have a flow that has gone through the meter of 8,224.7 Litres. To calculate this into

Gallons is easy 8,224.7 / 3.78 = 2175.84 gallons.

Flow Meter - Testing Meter

If your flow meter is working but is not recording data in your Dashboard or events, follow

the steps here:

1. Make sure sensor is configured [40] in the software.

2. Make sure controller is online. If not, please use link [41] for Wi-Fi troubleshooting steps.

3. Remove the wire splices at the flow meter connection in the field. Tap the two wires

together that run to the controller 10 times, as each contact will record a pulse.

Refresh the app to see if the flow usage was registered.

4. If app registered flow usage, your wiring and system are set up correctly. Reconnect to

the flow meter and run a large flow (lots of sprinklers) zone. Did you get a flow on your

app? If YES, all is OK. If NO, contact support@hydrawise.com [42].

5. If app did not register flow usage, test the sensor inputs on the controller. You can use

the same method with a paper clip or wire to make contact between sensor 1 or 2 and

the common terminal. Do this 10 times and then check for flow data usage at the home

screen. If YES, there is a problem with the wire running to the flow meter. If NO,

contact support@hydrawise.com [42].

IMPORTANT: Our controller is not polarity sensitive. There is no risk of electric shock when performing these

tests. However, if you feel uncomfortable, please contact a qualified technician or irrigation specialist for further

assistance.

NOTE: If it works at the controller end but not the flow-meter end, there is a wiring fault.

If it doesn't work at the controller end, contact support@hydrawise.com [42].

If it works at both ends, but still does not register flow on the app, contact support@hydrawise.com [42].

Flow Meter - Custom Flow Sensor

Configuration

To add a custom flow sensor, go to Sensors [43] from your web browser or smartphone

application.

1. Click Add Custom Sensor Type

STEP 1

A dialogue box will appear for you to enter your custom flow meter details. Make sure you

enter the calibration details for your custom pulse-based flow meter. Please refer to the

manufacturer specifications to find out the calibration. Otherwise, you will not get accurate

readings to display on your flow data.

NOTE: For our system to detect the correct flow data and reflect it on your Dashboard reports, any third-party

flow meter used must be a true pulse flow meter or have a reed switch. We aim for a minimum of 10 pulses per

min and a maximum of 120 pulses per min. That means if the flow rate was 10 gal per min, 1 pulse per gallon

needs to be set.

When using a third-party flow meter, please ensure it meets the specs above and is

calibrated correctly. Otherwise, data will not reflect accurately in reports. Also, note that the

wiring is not polarity sensitive. As long as you have one wire in a Sensor Port and a

Sensor Common, the device will work correctly. For flow meters that use three wires and

meet the specs above, configure the wiring until you find the two correct wires to use.

Single Flow Meter - Sharing Two

Controllers

For this installation, we suggest a few tips to make sure you do not receive any

unnecessary alerts.

When using multiple controllers on the same flow meter, there are two alerts we do not

recommend using.

1. High Flow Leak - High water usage with no zones running.

2. Slow Leak - Water usage over last hour with no zones running.

These alerts are controller specific so when the controller with the flow meter is not in

operation, it does know about the other controller operation.

Tips:

1. The inter station delay [44] should be set for 10-30 seconds. We do not recommend any

higher.

2. Change the gallons in the alert to be higher (e.g. alert from 5 gallons to 20 gallons).

Following these parameters should allow the system to run normal when using one flow

meter with multiple controllers.

Flow Meter - Winterization

We recommend that a qualified licensed contractor perform this type of winterization

method. The blowout method utilizes an air compressor with a cubic foot per minute (CFM)

rating of 80-100 for any mainline of 2" or less. The compressor is attached to the mainline

via a quick coupler, hose bib, or other type connection, which is located beyond the

backflow device. Compressed air should not be blown through any backflow or flow meter

device. For additional winterization procedures, we highly recommend contacting the local

dealer for the most common local practices. In the event you need to blow upstream from

where the flow meter is located, we recommend bypassing the meter by temporarily using

one of two options.

1. Installing a SCH 80 or galvanized nipple. See the size chart below:

Pump Start Relay Operation per Zone

Summary

When a system requires the use of a booster pump or pulls water directly from a creek or

pond, it’s imperative to include a relay to activate the pump each and every time. A pump

start relay is a relay box that activates a pump every time a zone is activated from the

controller. Zone valves are the individual valves that operate a group of sprinklers or drip

emitters. Hydrawise controllers support 6- to 54-zone valves, depending on the model.

Typically, one zone valve is turned on at a time and controls the irrigation in a specific area

of your landscape. Whenever one of the irrigation zone valves is told to open by the

controller, the controller also signals the pump start relay to turn the pump on.

Wiring (24 VAC)

Use a minimum distance of 15' (4.5 m) between the controller and the relay to dampen

electromagnetic noise. In addition to this recommendation, Hunter also recommends all

controllers be mounted 15' (4.5 m) away from pumps and high-voltage devices.

1. Detach the pump start relay cover plate by removing the four screws with

Phillips screwdriver.

2. Run a single wire from the "common" terminal on the controller to one of the yellow

wires on the pump start relay.

3. Run a single wire from the "P/MV" terminal on the controller to the other yellow wire on

the pump start relay.

4. Use wire nuts to make the connections and verify they are secure.

5. Install pump start relay cover plate and four screws. Close and lock the cabinet door.

6. Route wire through the conduit or one of the openings on the bottom of the cabinet.

7. Strip ½" (13 mm) of insulation from the ends of all wires. Secure the valve common

wire to “COM” (Common) terminal. Attach the opposite control wire to the M/V terminal.

Note: With an HC Hydrawise controller, any one of your 6 or 12 zones can be configured

to act as the pump start relay. We usually recommend wiring to the last zone that is not

being used in the controller.

Wiring to Power Source

NOTE: Connecting the pump start relay should only be done by a licensed electrician

following local codes. Improper installation could result in shock or fire hazard.

1. To prevent electric shock, turn the main circuit-breaker switch to “off” prior to making

electrical connections.

2. Assemble conduit piping and connect AC power from the power source to one side

(LINE IN) of the relay.

3. Assemble conduit piping and connect wiring from the pump motor to the other side of

the relay (LOAD OUT).

4. Check to make sure there are no exposed or loose connections.

Online Setup

This setup option is prompted when you first go through the initial setup wizard in the

software.

The online instructions will refer to a master valve but this same setting applies when

using a pump start relay.

Note: With an HC Hydrawise controller, any one of your 6 or 12 zones can be configured

to act as the pump start relay. We usually recommend wiring to the last zone that is not

being used in the controller.

Does your irrigation system have a master valve?

If you need to change this in the software after the setup wizard, refer to the instructions

below.

1. Log in to your Hydrawise account

2. Click on Zones and Schedules for the PC or Zones if using the mobile app.

3. Choose YES from the drop-down menu above the zones. If you have an HC controller,

choose the zone number to which you have the master valve wired.

Pump Start Relay Operation per Station

When selecting a pump start relay to be on/off for an individual zone, you can edit the

zone in Zones and Schedules under Advanced Settings. This option is useful when one

zone is using city water and another is using water from a different source.

Note: This option is for HPC and HCC controllers only.

Follow the steps below to change this setting:

1. From the Zones and Schedules page, click on the icon on the zone you would like

to edit.

2. Click on Advanced, which is located on the top blue search section.

3. Select Use Global Master Valve Setting to keep this circuit on or select Disable

Master Valve to turn it off.

One Master Valve - Two

Controllers

There are many times when two controllers are being supplied from a single POC (point of

connection) or source of water. Hydrawise-ready controllers can be connected to a single

master valve using a isolation relay (part number REL2). This device will allow for two

controllers to share the same master valve with out any issues.

The few limitations include:

Only one controller can operate at a time.

A delay of at least five minutes between the operation of controller #1 and controller #2

is desirable.

Electrical alerts will apply for each controller.

Steps for set up.

1. Wire the relay according to the drawing below.

2. Set up the master valve in the the app for both controllers using the normal instructions

in the article here [46].

3. Set up a new master valve using the app for controller #2 as per normal instructions.

REL 2 is NEVER connected to high voltage. It is for 24 VAC devices only.

Master Valve (P/MV) Operation per zone

Brief Summary

A master valve is a normally closed valve installed at the supply point of the main line that

opens only when the automatic system is activated. Zone valves are the individual valves

that operate a group of sprinklers or drip emitters. Hydrawise controllers support 6 - 54

zone valves, depending on the model. Typically one zone valve is turned on at a time and

controls the irrigation in a specific area of your garden. Whenever one of the irrigation zone

valves is told to open by the controller, the controller also signals the master valve to open.

The purpose of the master valve is to shut off the water to the irrigation system when none

of the zone valves are operating.

Wiring

1. Route the master valve wire between valve location and Hydrawise controller.

2. Attach the common wire to either solenoid wire. This is most commonly a white colored

wire. Attach a separate control wire to the remaining wire of each master valve

solenoid. All wire splice connections should be done using waterproof connectors.

3. Route wire through the conduit or one of the openings on the bottom of the cabinet.

4. Strip ½" (13 mm) of insulation from ends of all wires. Secure the valve common wire to

“COM” (Common) terminal. Attach the opposite control wire to the M/V terminal.
