Customer Question

My Honeywell chronotherm thermostat circa 80s seems to either be on or off without much regulatory control. Kids complain and shut it off too hot or complain too cold. Question: Manual clear tab on bottom with red green do I use it and when? Only controls heat. Air is separate. Thank you!

Hello and thanks for using this service, if you have been waiting do not worry or get upset I am just one of the techs on here and I try to get to as many customers as I can and I just picked up your question now. Please give me time to respond sometimes I get your replies late so there may be a delay in my response.

Well it may be time for a new thermostat those old Chronotherms can get out of range. You may want to upgrade to a Honeywell Vision Pro unit.

Here is a video to help you though on yours
