Question about Honeywell Heating & Cooling
Hey John, man that ole T87 has been around for a hundred years and I have installed many of them, but I cant remember the letters on the wiring. Seems to me that it is R-W-Y, any way you will use the R and W. I have a t87 at home still in the box and I could wait till I got home to help you but Im sure its the R and W terminal. Dont forget to set the heat anticipator. Set it the same as the current value of your gas or oil valve.
