There are three parts to a T87F thermostat. Outer ring, thermostat body, and base mount. Remove the snap on ring that goes around the dial. Remove three screws from the thermostat that mount it to its base. Remove the thermostat. Disconnect and record what screws each wire attaches to. Remove the screws holding the base to the wall.

You just need to used that 5 wires. The rest you leave blank. Your new thermostat has stage 2 heat and cooling also 1 for reversing valve which you don't need.

Two wire connection for honeywell rthl111b thermostat, heating only


What is your question?
If your asking if you can use a 2 wire connection from an older thermostat (most likely an old mercury switch) on the new Honeywell RTH11b
Yes you can.
You will lose some of the features of the thermostat but if all you want to do is turn the heater on and off it will do it.

If you are unsure about which wire goes where, that may be the source of your problem. The color coding can be confusing when changing from old to new. I pulled the instructions for my Honeywell CT3400A thermostat and found you can call Honeywell Consumer Services at 1-800-468-1502 M-F 7:30 am to 5 pm CT

I just installed a Honeywell 5.2 Day RTH2310B Programmable thermostat and I had to deal with the same situation: 2 wires, one white one black. After reading the edvice in one of the blog, the solution that worked for me was: BLACK ON Rc terminal and WHITE on W terminal. My furnace is running fine now. Hope it helps.

Honeywell round mercury thermostat - heat not coming on


If you tip the mercury switch so that it makes contact and the furnace doesn't start, it isn't the t-stat. Check the connections, then start checking the furnace.
In any case, ditch the mercury t-stat (recycle it properly) and get a new programmable one if at all posible. It will pay for itself many times over by turning your heat down in the middle of the night and back up by morning.

Honeywell therostat wiring help


Don't assume the wires at the thermistate are correct.

I had similar and had to go all the way back to the heat/AC controller board. I found the colors weren't attached per spec so was fighting the origional installation at the new thermistat.

Also some digital won't control mutizones proerly
