Wireless Indoor Sensor
Replace batteries in your indoor sensor when a warning
appears on the thermostat screen, about 60 days before
batteries are depleted.
When the sensor status light begins flashing red, battery power
is critically low and will be depleted within 2–3 weeks. During
normal operation, the status light remains off.
Indoor Sensor
has low batteries
Fig. 301.
To replace the batteries:
1. Remove the sensor from wallplate.
2. Install 2 fresh AAA alkaline batteries. If the status light
flashes green, batteries are good; if it flashes red, you
must use fresh batteries.
3. Attach sensor to wallplate.
The sensor will restore communication with the thermostat a
few seconds after new batteries are installed.
