1. Smart Hub

1.1. Installation

DO NOT install the Smart Hub on indoor unit, duct work or any equipment that could induce vibration.

Mount Smart Hub on flat surface away from indoor unit to minimize vibration. Securing module to a wall stud is desir

able. If mounted on metal surface other than above, antennas need to be perpendicular to the metal surface.

1.2. Antennas

Unfold both antennas to the vertical position. Adjustments may be required to optimized transmitting and receiving.

1.3. Wire Connections

1.3.1. Wire gauge and Maximum Run Length:

The Smart Hub connects to the indoor unit through common four-conductor thermostat wire. It receives 24VAC

power from the indoor unit over two wires and communicates with the indoor unit and the rest of the HVAC

system through two different wires. Wiring from the Smart Hub to the indoor unit should be limited to 300 feet or

less (for 18 AWG wire).

1.4. Troubleshooting

1.4.1. LEDs

These LEDs have a red LED chip and a green LED chip in the package and can show red, green, or amber

colors, steady or flashing.

NOTE: Smart Hub boot up time averages around 3 to 4 minutes.

The Smart Hub using spring loaded

push connectors for wiring connections.

Five indicators are located on the front of the Smart Hub enclosure

(near the top edge). One indicator location is reserved for future expan

sion and has no icon and no current function. The other four locations

have icons depicting Smart Hub functions and are back-lit by LEDs.

From left to right:

Wi-Fi – Indicates the status of the internal Wi-Fi module and whether or not it is connected to the home Wi-Fi

network.

Thermostat – Indicates the status of the thermostat Mag-Mount and HD Display and whether or not the Smart

Hub can communicate with the HD Display.

HVAC – shows the status of the HVAC equipment in the home controlled by this Smart Hub, and whether or

not the Smart Hub can communicate with them.

ALERT – shows if there is a critical alert condition.

Smart hub indicator display location

Figure 1. Smart Hub Indicators and Connectors

1.4.2. General Rules

S Unlit indicators show there is no power to the Smart Hub or its software has suffered a critical initialization

error.

S Steady amber indicators show Smart Hub boot up and self-check processes are in progress or have com

pleted. Boot-up and self-checks normally complete rapidly, so amber indicators may appear only briefly

(except for the Wi-Fi indicator).

S Flashing amber Wi-Fi indicator shows that the Wi-Fi module check is in progress. Steady amber Wi-Fi

indicator shows that the Wi-Fi module has passed its check but is not connected to the home Wi-Fi net

work.

S Flashing green indicators show acquisition and test of resources across wired interfaces to the Mag-

Mount / HD Display and to installed HVAC equipment

S Steady green indicators show that the associated function is connected and operating normally.

S Flashing red indicators shows a problem with the associated function.

S Flashing red ALERT indicator shows that a critical alert condition exists. If one of the other indicators is

also flashing red, that is the likely source of the alert. If no other indicators are flashing red, the source

of the alert is not defined.

1.4.3. Center Push Button Indicators

The center push button has a RGB (red-green-blue) LED backlight that indicates the Lennox-managed local

network communication status of the Smart Hub, and if the Smart Hub is transferring a software image from a

flash drive plugged into the USB port. While this LED indicator can show any color, it is currently limited to am

ber, green, or blue.

When the Smart Hub is in a normal steady state -- when the Smart Hub is in normal day-to-day operation -- the

center push button backlight shows:

S Steady blue when there is only one Smart Hub in the home and it is not connected to a mobile device

running a iComfort

S30 application.

S Steady blue when there is more than one Smart Hub in the home, but this Smart Hub is not connected

to any other Smart Hub.

S Steady blue when the Smart Hub is connected to another Smart Hub in the home through a Lennox-man

aged local network.

During various Smart Hub transient states -- when the Smart Hub is engaged in a special task that should

complete soon -- the center push button backlight shows:

S Steady amber (briefly) while the Smart Hub conducts self tests and boots up.

S Flashing amber while software or firmware updates for an iComfort

S30 system component or a con

nected field-upgradable HVAC asset is being transferred from files on a flash drive plugged into the Smart

Hub USB port.

S Steady blue while the Smart Hub conducts checks on its internal Wi-Fi module and remote HVAC assets.

(icon indicators show progress.)

S Flashing green when the Smart Hub is attempting a Lennox-managed local network connection with an

other Smart Hub in the home or with a mobile device running the iComfort

S30 service maintenance

application.

S Steady green when the Smart Hub is connected to a mobile device running the iComfort

S30 service

maintenance application through a Lennox-managed local network connection. (This is considered a

transient state because the mobile device will disconnect from the Lennox-managed network when the

task at hand is complete.)

1.4.4. Wi-Fi Connection

The following terminology is used in this troubleshooting section:

S Router Signal Strength (RSSI). RSSI is an indication of the signal strength of the Wi-Fi router being re

ceived by the scanning device (i.e., smart phone). Therefore, the higher the RSSI number (or less nega

tive in some devices), the stronger the signal.

S 802.11a, g and n are wireless networking specification that extends throughput up to 130mbps using the

2.4 GHz band.

S Internet Protocol Address (IP address). This is a numerical label assigned to each device (e.g., com

puter, printer, thermostat) participating in a computer network that uses the Internet Protocol for communi

cation. An IP address serves two principal functions: host or network interface identification and location

addressing.

S Electromagnetic Interference Causing Poor Connectivity

Locate both the thermostat and router away from other devices that could possibility interfere with wire

less communications. Some examples of other devices that could interfere are:

n Microwave ovens

n Wireless cameras

n Portable phones and bases

n Baby monitors

n Wireless speakers

n Bluetooth devices

n Garage door openers

n Neighbor's wireless devices.

To eliminate a possible source of interference, temporally disable any devices and see if Wi-FI perfor

mance has improved.

- 6 -

The Smart Hub may be relocated to a new location to obtained a stronger Wi-Fi signal connection to the

home wireless router. The Smart Hub may be place anywhere in the home as long as wiring can be run to

it.

S Router Signal Strength (RSSI)

The ideal signal strength range for the iComfort

S30 is -1 to -69 RSSI. The signal strength can be viewed

from the thermostat interface. Use steps 1

1. Press NETWORK SETTINGS; this screen shows a graphical view of buttons representing Wi-Fi op

tions OPEN and SECURE wireless networks and a button for adding a network.

2. Select the access point that has already been establish and connected too. When selecting the info

icon, a screen will appear which will display an option to forget the network and IP address assigned

to the iComfort

S30 by your router, sub-net mask, router, DNS and RSSI. The RSSI signal strength

is anywhere between -1 to -69, then the signal strength is sufficient. If outside this range, the either

locate the router closer to the thermostat or add a repeater.

Figure 2. Verifying Signal Strength

1.5. Electrical Voltages:

S Smart Hub Power In: 24VAC typical (18VAC to 30VAC range) at 1 Amp maximum from indoor unit.

S Smart Hub Power Out: 12 VDC (± 0.25 V) at 1 A maximum to Mag-Mount / HD Display

S Communication with Mag-Mount/HD Display: Two-wire serial RS-485 interface, 3.3-V signaling, up to 400

feet to Mag-Mount (18 AWG wire).

1.6. Networking Multiple Smart Hubs (Single Smart Hub Group) — Thermostat software release 3.00):

S If more than eight iComfort S30 Smart Thermostat HVAC are needed in a home, they can be segregated into

groups, with each group containing eight or less Smart Hubs.

n Group 0 is for a stand-alone Smart Hub or there is not desired to connect to other Smart Hub on the local

Wi-Fi network.

n Group 1 (default) is for homes with up to eight Smart Hubs and HD Displays that will communicate with

each other through the home wireless router. To change the Group ID, go to the Dealer Control Center

and touch equipment. Under the equipment list touch Smart Hub. Scroll down to the end of the list on

the right side of the screen until you reach Group ID. Change the Group ID to the desire number.

n Group 2 through 999 are for homes that require multiple Smart Hub groups consisting of up to eight Smart

Hubs per group.

S Currently each individual Smart Hub group is completely isolated from other local Smart Hub groups even if they

are all using the small home Wi-Fi router. HD Displays in one group can only control and access information

within its own Smart Hub Group.

S Selecting the home Wi-Fi network and entering the password must be repeated for each Smart Hub.

S When a second Smart Hub within a single Smart Hub Group connects to the home Wi-Fi network, it will automati

cally connect to the first Smart Hub the home Wi-Fi network. This is true for any additional Smart Hubs added

as well.

- 7 -

Limitations in software release 3.00):

From a single HD display, the following functions can not be controlled or viewed when interacting with other Smart

Hub within the same Smart Hub group.

S Away Mode

S Weather

S Date and Time

S Notifications

Advantages:

The isolation between groups may be used to good advantage if there is some compelling reason that an HD Display

in one part of the home should not be able to adjust the set point of a system elsewhere in the home. Assigning the

systems to two different Smart Hub Groups would allow this. An example of this might be to isolate the system in the

master suite or a guest bedroom from the HD Display in the children's area. The homeowner iComfort S30 mobile

application is able to see and interact with all Smart Hubs installed in the home even if they are spread among several

groups.

2. Mag-Mount

2.1. Mounting to 2x4 Electrical J-Box

2.1.1. Short Term Recommendation

Use Honeywell back plate from LPP store part # X5392.

2.1.2. Back plate - Long Term:

We will enlarge the existing back plate to cover 2”x 4” J box and replacement of larger stats with the iComfort

S30

2.1.3. Wiring Connections

2.1.3.1. Wire gauge and Maximum Run Length: The Smart Hub connects to the indoor unit through

common four-conductor thermostat wire. It receives 24VAC power from the indoor unit over two

wires and communicates with the indoor unit and the rest of the HVAC system through two differ

ent wires. Wiring from the Smart Hub to the indoor unit should be limited to 300 feet or less (for

18 AWG wire).

Figure 3. Mag-Mount Blue LED

S Steady - Mag-Mount is receiving power from the Smart Hub but HD display is not attached.

S Flashing - Mag-Mount is receiving power from the Smart Hub but is experiencing

some difficulty:

n It is not communicating with the Smart Hub is the most common issue

n There has been a software error in the Mag-Mount processor

n There has been an internal hardware error in the Mag-Mount

S Off - Possible causes:

n Mag-Mount is not receiving power from the Smart Hub. Check wiring at Mag-Mount and Smart Hub.

A mis-wiring will not cause any damage but will prevent the system from operating.

n There has been a serious Mag-Mount internal hardware or software failure which is a very remote

cause.

2.2.2. Electrical Voltages

The Mag-Mount provides 5-VDC to the HD Display at up to 1.5 Amps. The 12VDC supply from the Smart Hub is

reduced to 5VDC using a switching regulator on the PCB inside the Mag-Mount. A 6VDC TVS diode on the

5VDC output line will clamp the output voltage to a safe level if the regulator malfunctions and an over-voltage

condition occurs. The Mag-Mount has the ability to monitor the 5-V current drawn by the HD Display. When the

HD Display is not on the Mag-Mount, the 5VDC regulator is shut down, removing the 5VDC power from the HD

Display connector.

8.5. Reconnecting iComfort Mobile Setup Application to System at a Later Time

Trouble connecting the iComfort Mobile Setup Application to the Smart Hub for follow up servicing. Your mobile de

vice's Wi-Fi does see the Smart Hub's SSID and connects to it, but the iComfort Mobile Setup Application does not

Application will be able to detect the Smart Hub and connect to it. Go to thermostat home screen and touch the menu

icon. Touch settings and then wi-fi to access the Wi-Fi setting screen. Toggle the option to OFF.

Troubleshooting

1. Wireless Connection between Mobile Device and Smart Hub

Issue: Your mobile device (smart phone or tablet) will not connect to the Smart Hub using the procedures in the installation

and setup guide. Then try the following possible solution.

Solution: Disable mobile data on your device if applicable.

S Android 4.4 - Go to Settings > Wireless & Networks > More > Mobile Networks > Data Enabled and un-check

this option

S Android 5.x - Go to Settings > Connections > More Networks > Mobile Networks > Mobile Data and unchecked

this option.

S IOS - To turn off cellular data, tap Settings > Cellular on your iPhone or Settings > Cellular Data on your iPad.

Disable Cellular Data and Data Roaming.

S Note: When mobile (cellular) data is successfully disable, Icons for 2G, 3G or 4G will not longer be present on

the main screen.

Try to connect to Smart Hub. Reports indicate that disabling mobile data will reduce the interference that may be causing

the connection issue.

REMINDER: Do not forget to turn your mobile data setting back on when you are finished with the Lennox Mobile Setup

application.

2. Mag-Mount (Front Cover) and HD Display

Issue: When mag-mount is powered and the HD Display is not attached there is a bright blue LED that can be seen on the

front. If it is solid blue then you have voltage. It also indicates the mag-mount is communicating with the smart hub. If the

blue LED is blinking that means that the mag-mount has proper voltage but is not communicating. This may indicate a

wiring issue.

Solution: Verify that when you reinstall the mag-mount front terminal cover to make sure it sets flush with the base. There

has been three systems replaced due to the cover not being reinstalled properly. This issue was caused by extra wiring left

in the terminal area kept the cover from going down all the way. If this happens the HD Display will not be powered. What

happens is the display will try to start but then go blank or bring up a pop up saying it can not connect. A quick look at the top

of the mag-mount looking down through the vent holes on the mag-mount you would see the blue light on. When the HD

Display is making contact their will be no blue light on.

4. Mag-Mount (Mounting Screw) and HD Display

Issue: There has been a few instances were the Mag-Mount screw used to secure the device to the wall at the 6 O'clock

position pushes the Mag-Mount out enough to sever the electrical/communication connection between the HD Display and

Mag-Mount.

Solution: Remove the 6 O'clock mounting screw and use only at the 3 and 9 O'clock position to secure the Mag-Mount to

the wall.
