We bought a new thermostat, and tried to hook it up, but we are not clear which wires should go where. The old Thermostat (White-Rodgers) Had Y, W, G, RC and RH terminals. The Yellow wire was connected to Y The White wire to W The Green Wire to G The Red wire to RC and RH. The New thermostat has: R, Y1, W2, E, O, B, G, L and C terminals. For a York system the manual for the thermostat seems to say we don't need the B and to Jump the E from the W2. We hooked Red to R Yellow to Y1 White to W2 (then E) Green to G There are Blue, black, Brown, and orange wires coming out of the wall with the other thermostate wires, but were not hooked up to the old thermostat. There are O, B, L and C terminals on the thermostat which have no wires.

I have an 8 year old Rheem that has been freezing the indoor coil while in cooling mode, several techs have inspected and said that there was probably a freon leak. When switching to heat mode, the high pressure quickly jumps to 300, where it cuts off. This doesn't make sense if the freon charge is low? Indoor/outdoor coils are clean, blower is working fine, no apparent duct leaks. Ideas?
