Honeywell C7189R1004 Wireless Indoor Sensor for Prestige 2.0 Thermostats

The Wireless Indoor Sensor(s) is used to change the sensing location of the thermostat.

This sensor monitors temperature and humidity in any indoor location and transmits it wirelessly to the thermostat. You can set the system to monitor temperature at the thermostat, or at the sensor location, or use an average of both to optimize comfort throughout the home. The thermostat can accommodate and average temperature readings from as many as 6 sensors.  When multiple sensors are installed, the thermostat can monitor temperature and humidity in separate locations, and you can set it to use different readings from different sensors.  For example, one sensor can control humidification on the main level, while another controls dehumidification in a crawl space. For more information, see the instructions provided with the thermostat.
