C7189U Remote Indoor Sensor
(USE WITH VISIONPRO
This indoor sensor is designed to sense temperature at a remote location and send this information to the VisionPRO
Thermostat. This sensor can be used as a stand alone sensor or as part of an averaging network. 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).
