Honeywell DT200 thermostat is not responding to any buttons pressed. Display is showing small flame icon on left of screen and what looks like a battery in top right hand corner. Any suggestions?
The thermostat is calling for heat, and the battery icon means that the batteries are low and should be replaced. If the thermostat is wired to run on battery power alone, replacing the batteries usually corrects this problem. Hope this helps! Jim
