Wiring; Operation; Wiring A Single C7189U Sensor; Inside Temperature Reading On Th8000 Series Thermostat - Honeywell C7189U Installation Instructions Manual

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.

OPERATION

Once a remote indoor temperature sensor is connected to
the thermostat, the thermostat's sensor is no longer used.
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.
