C7189U Remote Indoor Sensor
APPLICATION
This indoor sensor is designed to sense temperature
at a remote location and send this information to the
compatible Honeywell Home thermostat. This sensor
can be used as a stand alone sensor or as part of an
averaging network. The thermostat's installer setup
should be modified to tell the thermostat that remote
indoor temperature sensor(s) have been used. If
multiple wired indoor sensors are used, those sensors
are averaged and must be wired as shown in Fig. 6.

CAUTION
Electrical Interference (Noise) Hazard.
Can cause erratic system operation.
Keep wiring at least one foot away from large
inductive loads such as motors, line starters,
lighting ballasts and large power distribution
panels.
Use shielded cable to reduce interference
when rerouting is not possible.
