Honeywell RTH230 Thermostat Battery Change

Asked May 26, 2008, 11:47 AM — 1 Answer
I recently changed the AA batteries on a Honeywell RTH230B Thermostat and now the heat or air will not kick on. The symbol for air or heat will flash on the screen for approximately 2 minutes then I'll hear a click and the symbol will stay lit but the heat or air will not flow. Does the thermostat have to be rebooted like a computer? I followed the instructions when replacing the batteries by turning the thermostat to the off position before replacing. What can I do to correct the problem?
