The thermostat has wires connected to G, C, R, Y, E, & B. There is a jumper bar between W1 & Y and a jumper wire between W2 & E. I guess my first question involves the jumper bar between W1 & Y. The manual for the thermostat states that the ???jumper should be removed for systems with separate heating compressor contactor (W1 separate from Y).??? W1 and Y are indeed separate at my air handler.
