I tried replacing the batteries twice. The first time the thermostat worked
fine for a couple hours but after that it shuts off and says 'lo bat'. I
referred to the users manual and got nothing.
Thanks, people.




Had same problem with same stat. This worked for me. Pull cover.
heat/off/cool switch to off. Remove batteries. remove red and white wires
(which supply 24 volts to the circuit) hit reset button. Wait 20 minutes.
restore red and white wires, put in batteries. Hit reset again. Wait 2
minutes and it should work.
Basically cut all power for a while and reinstall. Manual apparently
states batteries should be replaced with switch in off position but my
quess is most people don't read the manual. This looks like a basic
software bug. Good luck.
