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

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.

Remove 3 to 4 inches of the cable’s outer sheathing, then remove
3/8 to 1/2 inch of insulation from each wire.
