Question about Honeywell CT87B ROUND HEATING&COOLING MECHANICAL THERMOSTAT - WHITE Heater
I installed a honeywell thermostat in my house last summer. I've installed thermostats before and never had any problems but this one is a nightmare i went threw like 3 before i found one to work with all he wires. i eventually found a more up to date version of what it originally had. well now i turn on my heat and it runs fine except for it wont cut off but the E-heat works just fine and cuts off and th a/c works just fine. i've checked and double checked and the wiring is correct to the best of my knoweledge.I need to figure this out without another $200 bill from the hvac men. Heat comes on but won't cut off. Trying to find info to set Cycles Per Hour (CPH) or heat spread on this thermostat. The Heating & Cooling is a Single stage heat pump ... Straight Electrical and old as the hills. It's on top of the roof so I don't know the make and model of the pump. Bought and was going to replace it with a Honeywell TH5110D digital unit ... but seeing the wiring in this thermostat don't think I''ll chance it. Too cold to be without heat for three of four days.
Whan your room is up to temp or room is set at 70 and your stat is at 70 do you hear the stat click off .if not its a bad stat. you will have a little flam on your stat that should go off also
