Battery Replacement
Wireless Indoor Sensor
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 2–3 weeks. During normal operation, the status light
remains off. After new batteries are installed, the indoor sensor
will restore communication with the wireless network within a
few seconds.
NOTE: After installing batteries, the status light may
glow amber for up to 20 seconds. Please wait
while the indoor sensor restores communication
with the wireless network.
Wireless Outdoor Sensor
Replace batteries in your outdoor sensor when a warning
appears on the thermostat screen, about two months before
batteries are depleted.
After new batteries are installed, the outdoor sensor will restore
communication with the wireless network within a few seconds.
Portable Comfort Control
Install fresh batteries when the REPLACE BATTERY warning
flashes on the screen. This warning will flash for approximately
two months before the batteries fail.
After batteries are installed, the remote control will
automatically restore communication with the wireless network
within a few minutes.
