C7189U REMOTE INDOOR SENSOR WIRING The sensor can be used to provide one remote sensor (see Fig. 6) or as a temperature averaging network with multiple sensors connected (see Fig. 7). The thermostat is not part of the average network. CAUTION ELECTRICAL HAZARD. Can cause electrical shock or equipment damage. Disconnect power before wiring. 1. Run the wire cable from the thermostat to the remote sensor location. 2. Loosen screw terminals, insert wires into terminal block (polarity does not matter), then retighten screws. 3. Push excess wire back into the wall opening. 4. Plug the wall opening with non-flammable insulation to prevent drafts from affecting the sensor operation and replace the cover on the remote sensor. 5. Connect the two wires to the thermostat's remote sensor terminals (polarity does not matter) and replace the thermostat back onto the wallplate. See Fig. 6. M24116 Fig. 5. Terminal block wiring.

The thermostat's installer setup should be modified to tell the thermostat that remote indoor temperature sensor(s) have been used. The Inside temperature reading on the thermostat's display will be the remote sensor(s) temperature location(s). See Fig. 8. 1 SENSORS MUST BE ARRANGED IN THIS CONFIGURATION TO OPERATE CORRECTLY. 2 WIRES MUST HAVE A CABLE SEPARATE FROM THE THERMOSTAT CABLE. M19973 Fig. 7. Wiring Multiple C7189U Sensors. .
