Installation Recommendations
WARNING
Improper installation, adjustment, alteration, service or maintenance can cause
property damage, personal injury or loss of life.
Installation and service must be performed by a licensed professional HVAC
installer (or equivalent) or a service agency.
Before beginning installation, note the type of equipment, number of stages, and
any accessories being installed.
Do
• Read this entire document, noting which procedures pertain to your specic
equipment and system requirements.
• Make sure that all wiring conforms to local and national building and electrical
codes and ordinances.
Do Not
• Install on voltages higher than 30VAC.
• Exceed 300 feet (91 meters) run when using 18 GAUGE thermostat wire or larger.
• Allow power load from any thermostat connection to be more than 1 AMP.
Smart Hub Installation, External Components, LEDs, Terminals & Jumpers
1. Things to consider when installing the Smart Hub:
• Install the Smart Hub near the indoor unit such that there is a direct path to
the approximate location of the home Wi-Fi access point (the signal is not
blocked by the indoor unit or duct work, for example).
• The Smart Hub can be attached to a vertical surface such as a wall stud
or roof truss web, or to a horizontal surface such as a oor or ceiling joist,
or a roof rafter.
• The Smart Hub antenna should be positioned such that it is roughly vertical,
no matter the orientation of the Smart Hub, itself.
• Do not install the Smart Hub on the indoor unit, duct work, or other
equipment that could induce vibration in the Smart Hub.
• Do not install the Smart Hub on or near large metal objects. This could
adversely affect the range and directional coverage of the Smart Hub Wi-Fi
signal.
• If the Smart Hub MUST be installed on a metal object, orientate the antenna
perpendicular to the metal surface.
• In all cases, the Smart Hub antenna orientation may need to be adjusted to
obtain best Wi-Fi results.

The following diagrams illustrated the basic Lennox communication control wiring
for all compatible components.
DisChargE air tEmpEraturE sEnsor (Dats)
• Installation of discharge air temperature sensor (DATS) (88K38) must comply
with the following requirements:
• Installed downstream of the heat exchanger or electric heat elements.
• It must be placed in free airow, where other accessories (such as humidiers,
UV lights, etc.) will not interfere with its accuracy.

11
outDoor air sEnsor (oas)
The optional outdoor air (temperature) sensor (OAS) (X2658) wiring distance to
either the furnace or air handler control should not exceed 200 feet (61 meters)
when wired with 18 #AWG thermostat wire. Installation of OAS must comply with
the following requirements:
• Sensor wiring must be run to avoid touching or being close to high voltage wiring
and light ballast.
• Choose a protected outdoor location away from direct sunlight or other heat
sources (usually on the north side of the building).
• Ensure that water will neither collect on, or wash over the sensor.
• Do not locate the sensor near driveways or similar heat-absorbing masses which
may reect stored heat energy onto the sensor and send inaccurate information
to the thermostat.
• Locate the sensor away from attic and soft vents, or furnace venting pipes.
• Do not locate the sensor directly above an air conditioner or heat pump.
Wiring spECiFiCations
The following is the wiring specication for the system:
• Smart Hub to Mag-Mount wiring size is 18 #AWG.
• Thermostat does not required shielded cable wiring.
• Maximum total length of all connections combined is 1500 feet (457 meters).
• Maximum length between components is 300 feet (90 meters).
rEDuCing ElECtriCal noisE on CommuniCation Bus
Communicating systems requires four thermostat wires between the Mag-Mount
and Smart Hub. Four wires are also used between the Smart Hub and indoor/
outdoor units as well.
When a thermostat cable with more than four wires is used, the extra wires
must be properly connected to avoid electrical noise. The wires must not be left
disconnected.
• Use wire nuts to bundle the unused wires at each end of the cable. A single
wire should then be connected to the indoor unit end of the wire bundle and
attached to the “C” terminals as shown in “Figure 4. Thermostat Wire Termination
in Communicating Systems (Electrical Noise)”.
• Keep all communication wiring as far away from the house electrical wiring and
large electrical appliances as possible. Recommended minimal distance is 15
feet (5 meters).

How to Operate the Smart Hub
A temporary Smart Hub local network provides a means for a mobile device using
the iComfort Mobile Setup application to communicate directly to the Smart Hub.
The iComfort Mobile Setup application running on a mobile device cannot reach
the Smart Hub through the Internet or home Wi-Fi network.
The mobile device must be:
• Wi-Fi capable
• Located in the home near the Smart Hub
NOTE: A router with Bonjour capabilities is required for this function. Check the
router functions if the Smart Hub does not connect. Apple Bonjour®is an
implementation of Zero-conguration networking (Zeroconf), a group of
technologies that includes service discovery, address assignment, and
host name resolution.
This application tool is used by dealers to commission a iComfort E30 smart
thermostat using a Wi-Fi enabled mobile device.
Commissioning (Using the Mobile Setup Application)
This application tool is used by dealers to commission a thermostat system using

multiplE smart huB(s)
Multiple Smart Hubs in a home can be assigned to a group (up to nine groups with
up to eight Smart Hubs in each group). All Smart Hubs in a group can communicate
with other Smart Hubs in the same group over the home Wi-Fi network.
Default is Group ID is 1. Range is 0 to 9.
For example, seven Smart Hubs in a home can be divided up for example as 1 in
Group 1 and six in Group 2 or 4 in Group 1 and 3 in Group 2. Smart Hubs in Group
1 will not be able to see or interact with the Smart Hubs in Group 2. This allows the
intentional isolation of the Smart Hub for the master bedroom from the Smart Hub
for the children’s area, for example.
If a Smart Hub is set to Group 0, there will be no connectivity with another Smart
Hub.
rEBooting smart huB
Pressing the Smart Hub button for more than ve seconds will reboot the Smart
Hub.
Commissioning (Using the HD Display)
