Once power is connected, the “Compressor” (or “Boiler”) LED should

Fig. 9.
7. For compressors and boilers:
Put the thermostat in pairing mode.
New thermostat installation: When going through the initial setup
the thermostat display will ask “TSTAT CONTROLS AN EQUIP
MODULE”. This refers to an EIM, not an ERM. See note below.
The next screen says “connect RedLINK Accessories?” The
ERM is an accessory, so select “yes”, and then “next”.
Existing thermostat installation
: Select menu - installer options -
wireless manager - add device. See thermostat installation guide
for assistance.
NOTE: The ERM (equipment remote module) is not an EIM (equipment
interface module).
• If using a Prestige IAQ thermostat, the EIM (THM5421R) is
always needed, whether the ERM is used or not.
• If using a RedLINK VisionPRO model, the EIM is not needed if:
(a) there are wire connections to R and C at the thermostat
subbase and the thermostat controls hot water heat
only (no cooling).
(b) the R and C as well as furnace or air-handler wires are
connected to the subbase of the thermostat.
8. Once the thermostat is in pairing mode, press and quickly release
the “Connect” button on the ERM.
