Question about Honeywell Air Conditioners
SOURCE: I have a Honeywell T8400C
Try taking the batteries out for 5 min,or disconnect power for 5min.
To clear it out.
Then re input all your times days and temps,
Is t stat in a cold location near a door or window?this could also override your settings,most progrmamble stats will go into override at 58.f im guessing this is not your problem.
If it continues after you reset,i would consider a new thermostat.
Hope this helps.
