I have a second hand Honeywell Thermostat that I was going to give to some one else to use as I already have one. I do not have instructions to go with this unit and I am only dealing with a two wire hook up. Can you tell me which screws I am to attach these to. Thanks and may God bless. Carl French

If you only have heating . You connect one wire to the R terminal and one wire to the W terminal
