Installing Equipment Interface
Module (if used)
If no Equipment Interface Module is used, skip to “Selecting
Thermostat Location” beginning on page 10.
NOTE: If an EIM is mounted inside a metal cabinet, it is
recommended to use a THM4000R1000 Wireless
Adapter for extended wireless range. Mount the
Wireless Adapter outside the metal cabinet and
connect to the ABCD terminals at the EIM.
NOTE: If you install more than one thermostat and EIM,
the EIMs must be at least 2 feet apart for best
RedLINK performance.
CAUTION
Electrical Hazard.
Can cause electrical shock or equipment damage.
Disconnect power before wiring.
The Equipment Interface Module (EIM) can be mounted
vertically on the HVAC equipment or on a wall in the equipment
room.
1. Mount the EIM near the HVAC equipment, or on the
equipment itself. Use screws & anchors as appropriate
for the mounting surface.
2. To wire the EIM, strip 1/4” insulation, then insert wires
(see Fig. 6). For wiring diagrams, see “Wiring” beginning
on page 116.
Fig. 6.
NOTE: Link EIM to thermostat BEFORE linking any
RedLINK accessories. See “Linking RedLINK
Accessories” on page 13.
3. If you are installing discharge and return air sensors, see
“Selecting Discharge and Return Air Temperature Sen-
sor Mounting Locations” beginning on page 8).
Wiring 24 Vac Common
• Single-Transformer System—Connect the common side of
the transformer to the C screw terminal of the EIM. Leave
the metal jumper wires in place between R, Rc, and RH.
• Two-Transformer System—Connect the common side of the
cooling transformer to the C screw terminal of the EIM.
Remove the metal jumper wire between Rc and Rh.
Connect the hot side of heating transformer to Rh and leave
the jumper wire between R and Rc and connect the hot side
of cooling transformer to R or Rc.
