How do I Troubleshoot "Bat Lo" Won't Reset on a Honeywell Programmable Thermostat?
- 1). Open the thermostat's battery compartment with a small coin.
- 2). Remove the old batteries by pressing down on the left end of both batteries.
- 3). Install two fresh alkaline batteries.
- 4). If "bAt Lo" indicator won't reset after this step, remove batteries and install them backwards for five seconds.
- 5). Remove batteries again and install them correctly.
- 6). Reprogram thermostat after thermostat displays "1:00pm."
