Question about Honeywell CT87B ROUND HEATING&COOLING MECHANICAL THERMOSTAT - WHITE Heater

1 Answer

My heat wont turn off

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.

If you have an emergency heat position we will assume you've got a heat pump. If you do not have a heat pump you have the wrong thermostat for your application. Need model of this thermostat, wire colors, termiation points (what terminal designator they are connected to), and if you have it where they were and the model of the last thermostat that worked correctly

No heat after installing honeywell thermostat H8110U


hook up the blue wire in the furnace cabinet where the blower section and the other thermostat wires are connected to the furnace. the thermostat you have uses a common wire from the thermostat to the furnace and this needs to be hooked up in the furnace otherwise you will have the problem you are having.
