To replace the batteries in the Alarm.com Smart Thermostat:
- Remove the thermostat from the back plate by pulling the thermostat straight out and off the wall.
- Take out the existing batteries.
- Insert the new batteries following the specified polarity markings on the thermostat.
- Return the thermostat to the wall plate by pressing the thermostat body firmly into the back plate mounted to the wall.
Important: Verify that the pins on the body are correctly aligned with the back plate. Failure to do so could cause damage to the thermostat.
