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 must be used with updated

THX9421R5021, TH8321R1001 and/or EIM. Look

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 exterior

wall near the compressor. The location should be at least 3 feet

above ground and oriented with the two wire exits facing

downward. See Figs. 11 and 12.

10. Attach cover and secure with bottom screw (Fig. 13).
