How do you unlock the temperature on a Honeywell thermostat? My mother's thermostat will only go to 72. Please Help! My mother is very cold!
Can you provide the model number of the thermostat? Have you tried taking the batteries out and turning the power to the furnace off for 30 minutes? This should default it back to original settings and then you will have to set it up again.
Yes, I've tried taking the batteries out but I did not turn the power to the furnace off.
The model of the thermostat is TH 5110D1022
I found this online...will this reset the settings?
"One can always "Override" the preset schedules by setting the temp at desired setting and pressing "Hold". If Hold is not pushed after setting temp it will only temporarily be set and revert back to the factory or preset schedule at the preset programmed time.
OK to do the reset here is what your looking at but will take you back to a clean slate.
This will reset ALL settings even the heat pump or non heat pump, single stage 2 stage, etc....ALL of them and you will have to start from scratch to set up thermostat like when you first installed it
Ok to do a reset as follows:
Will this work for me? If I do this can I then just press the up and down to control the heat?
Yes, it'll work but you will have to reprogram all settings into the thermostat. I take it you have the booklet on this one?
If not, here's the guide.click here
When you say I'll need to "reprogram all settings into the thermostat" what does that mean exactly?
I apologize, I just realized this is a non programmable thermostat, so there is no hold button. Just use the up and down arrows to set temp. Too many things going on at once! :~(
