I had a honeywell T87F It has four wires and the red wire connected to two terminals the rh and r terminal. I was given a lux 1500 programable thermostat I conected the four wires to the co-ordinated colors G, Y, W & RH. do I have to connect the red wire to any of the remaining terminals B, O or RC. and can someone tell me where to get instructions on installation.
Thank you
