My thermostat will not stay at the setting I set it at. When I come home at night the setting has increased to 85 when I have set it for 78
My husband set the thermostat for 78 and it comes on and runs find but when we come home at night the house is so hot and when we check the thermostat has risen to be set for 85 or so. why does it not keep it original setting.

Instructions1 On nearly every Honeywell thermostat, the heat setting can be increased by simply pressing the HEAT option or AUTO and using the arrow keys to adjust the setting higher or lower until the desired temperature is reached. 2 To set an automatic heating schedule for Wake, Leave, Return and Sleep, press the SCHEDULE button, then EDIT. 3 Select the current day and use arrows to select the time and temperature for Wake. For example, if you typically awake for work at 6:00 a.m. and want the heat to come on, use that as your Wake time and adjust the temperature to suit. 4 Select the day and use arrows to select the time and temperature for Leave. Since you will be leaving the home empty for several hours, this setting will allow the thermostat to lower the heat until your arrival back home. 5 Select the day and use arrows to select the time and temperature for Return. This is the time and temperature that you will choose for returning home from work and may want the heat on to warm the house for your arrival. 6 Select the day and use arrows to select the time and temperature for Sleep. Set the time you normally go to bed. The thermostat will automatically adjust itself to your selected temperature at that time. Thanks
Try it with out the programming. There is no fix if the dates and times are correct. Before you call someone you are better off buying one online ($150) and changing yourself. Should not even have to do any wiring, just remove screen and put new one on old backplate. Of course you will have to redo all your run times with the new one. Likely pay that much for the service call just to hear you need a new one. Good luck.
The Honeywell Vision Pro 8000 can be complicated to figure out if it isn't set up right from the system menu. There are so many things that you can make it do, sometimes the most common things are wrong. My question is ''what kind of system do you have, heat pump or not?, and is the system gas or oil?" If I knew these things, I could definitely help you figure out if the thermostat is set up right. I have the manual so that I can give you exact numbers. Just in case, you can email me at : [email protected]
If your furnace has a filter or fan compartment door, be sure it closed tightly and that the filter is installed correctly - there could be an interlock switch that is preventing the thermostat from operating. Also, if you haven't already turned off the power to the furnace, do that, wait a minute and then turn it back on.
Obviously, make sure the thermostat is on, is set to heat and calling.
I never liked the user un-friendliness of the Chromatherm, I would suggest finding a thermostat that you can understand and operate. Yes the Chromatherm is a good one, but so damned hard to figure out. Stay away from thermostats that still use mercury. Good Luck!
