Battery replacement: Wireless indoor sensor
Replace batteries
in your
indoor sensor
Install 2 fresh AAA alkaline batteries. Status light will briefly flash green.
If it flashes red, batteries are not good.
Replace batteries in your indoor sensor when a warning appears on the
thermostat screen, about two months before batteries are depleted. When the
sensor status light begins flashing red, battery power is critically low and will be
depleted within 3 weeks. During normal operation, the status light remains off.
After installing batteries, the status light will glow amber for 20 seconds. Please wait while the indoor sensor
restores communication with the wireless network.
