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.
