Guidelines for Installing RedLINK
Devices
— When installing more than one Thermostat and
Equipment Interface Module, mount the Equip-
ment Interface Modules at least 2 feet apart for
best RedLINK performance. No minimum distance
is required between the Thermostats if the Thermo-
stat is linked to an Equipment Interface Module.
— When the Thermostat is wired directly to the equip-
ment (No Equipment Interface Module and No
TrueZONE Wireless Adapter), mount the Thermo-
stats at least 2 feet apart for best RedLINK perfor-
mance.
— To determine if a RedLINK device will communicate
properly in the installed location, during the con-
nection process, press and quickly release the con-
nect button on the RedLINK device at the desired
mounting location. 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 connection 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 Wire-
less Adapter, you will NOT be able to do the follow-
ing: control 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 fea-
tures, wire the Thermostat directly to the zone
panel or use an Equipment Interface 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/Equip-
ment Interface Module. See page 136 for more
information.
