Honeywell thermostat jumping to 83
Hello all -
Our Honeywell thermostat is currently set to cooling and the temp manually set to low 70’s. Every couple of hours it will reset to 83.
I am out of town for the week and the outside temp will be in the 90’s F this week. My wife would prefer to not roast this week.
Does anyone have any suggestions on how to fix the thermostat so it stays at the temp we set to?
We don’t use a program. We manually set the temp and leave it. It hasn’t been a problem in the years we have had this thermostat.
I believe it is a Honeywell RTH6350D.
Thank you for any suggestions.
