About the ERM5220R
Fig. 1.
• Wireless RedLink™ communication between condensing unit/
compressor or boiler and thermostat.
• Eliminates the need to run additional wires to your equipment, for
example, during a heat pump upgrade.
• Suitable for outdoor use.
• Temperature sensor terminals for outdoor temp sensors or indoor
freeze protection.
• LEDs for easy installation checkout.
• May reduce damage to homes since wiring/drilling is eliminated.
NOTE: The ERM5220R is compatible with updated
models THX9421R5021, TH8321R1001,
TH8320R1003, and TH8110R1008.
THM5421R1021 EIM is also required with
THX9421R5021. Optional with other models.

INSTALLATION
IMPORTANT
• The ERM is not compatible with RedLink Zone boards.
• To ensure that the ERM will receive a wireless signal at the
desired installation location, follow steps 1 to 5 in the Wiring
section.
• If your location has metal siding, the ERM’s signal may be
affected. If there is no communication or poor signal strength,
consider a different location.
• A Prestige (with EIM) or VisionPRO (with or without EIM) will
only allow one of the following configurations:
1) Enrolled with a single boiler configured ERM;
2) Enrolled with a single compressor configured ERM;
3) Enrolled with a single boiler configured ERM and enrolled
with a single compressor configured ERM.
Wiring
1. Make sure power to compressor/boiler is off.
2. Remove the front cover by loosening the cover screw and lifting
up from the bottom of the ERM.
3. Remove 3 to 4 inches of the cable’s outer sheathing, then
remove 3/8 to 1/2 inch of insulation from each wire.
Fig. 4. Cable prepared for wiring.

4. For compressor applications: Leave the jumper between termi-
nals J and R in place.
For boiler applications: Remove the jumper between terminals
J and R.
Fig. 5. Terminal Designations showing the jumper
between J and R terminals.
5. For compressors and boilers: Connect a 24 VAC power source
to the R and C terminals on the ERM.
Fig. 6.
6. Connect terminals from the ERM to the appropriate terminals
on the compressor/boiler control board.

IMPORTANT
If the ERM was previously used with a compressor and will now
be used with a boiler:
1) un-enroll the ERM at the thermostat;
2) remove the jumper on the ERM;
3) designate Radiant Heat for Heating System Type
(ISU 2000) in your thermostat.

Once power is connected, the “Compressor” (or “Boiler”) LED should
illuminate green. (Fig. 9)
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.

When the ERM is connected to the system, the ERM’s “Connected” LED will be
solid green and the thermostat will show “ERM” in its Wireless Manager. (Fig.
10)
Fig. 10.
Mounting ERM
9. Use two screws and wall anchors to attach the ERM to the exte-
rior wall near the compressor. The location should be at least
3 feet above ground and oriented with the two wire exits fac-
ing downward. See Figs. 11 and 12.
10. Attach cover and secure with bottom screw (Fig. 13).
