Installing and Changing Batteries

For Battery Thermostat Operation
If your LCD is blank, or displaying LO BAT, the batteries are not installed or need to be changed. We suggest you change the batteries at least once a year, or whenever the LO BAT warning displays.
Remove the cover, and install the two “AAA” alkaline batteries into the battery compartment. Proper battery installation is important! Make sure the positive ends of the batteries match the positive terminals in the battery compartment. For Hardwired Thermostat Operation
Batteries are not required when a common wire is connected to the C terminal of the SC2010 N/Lthermostat.
