Guidelines for Installing RedLINK
Devices
— When installing more than one Thermostat and Equip-
ment Interface Module, mount the Equipment Interface
Modules at least 2 feet apart for best RedLINK perfor-
mance. No minimum distance is required between the
Thermostats if the Thermostat is linked to an Equip-
ment Interface Module.
— When the Thermostat is wired directly to the equipment
(No Equipment Interface Module and No TrueZONE
Wireless Adapter), mount the Thermostats at least 2
feet apart for best RedLINK performance.
— To determine if a RedLINK device will communicate
properly in the installed location, during the connection
process, press and quickly release the connect button
on the RedLINK device at the desired mounting loca-
tion. If the RedLINK device connects, then it will work
reliably during normal operation. If the RedLINK device
does NOT connect, try a new location. During the con-
nection process, the signal is sent at low power and
during normal operation the signal is sent at high
power.

— To connect a RedLINK device, make sure to press and
quickly release the connect button on the RedLINK
device. Press and holding the connect button down too
long will not allow the device to connect.
— If you link the Thermostat to the TrueZONE Wireless
Adapter, you will NOT be able to do the following: con-
trol humidification, dehumidification or ventilation, setup
a program schedule remotely from a computer, smart
phone or tablet, work with the Wireless Indoor Sensor,
Entry / Exit Remote or the Vent and Filter Boost
Remote. To use these features, wire the Thermostat
directly to the zone panel or use an Equipment Inter-
face Module.
— If you are using a RedLINK device from a previous
installation, you must reset the device first before you
re-connect it to the new Thermostat/Equipment Inter-
face Module. See page 134 for more information.
