Replacing outdoor sensor batteries
Replace batteries in your outdoor sensor
when a warning appears on the thermostat
screen, about 60 days before batteries are
depleted.
To replace the batteries:
1 Remove the sensor from the bracket.
2 Detach cover.
3 Install 2 fresh AA lithium batteries.
4 Replace cover and set sensor back into
bracket.
The outdoor sensor will restore
communication with the thermostat a few
seconds after new batteries are installed.
