Ok I am getting ready to study the wiring diagram but thought in case it seemed like greek I'd put out a call for help co-worker called H/W about this so I was in the dark til the sat call.Pro 3000 thermostat when h/o put on heat (for the heat pump ) fried the 24v transformer then on e-heat the fan will not shut off unless he (h/o) turns down temp. 2 degrees. I know a wire is screwed up it is a York heat pump solid state control module with h/w thermostat Ok I will study the wiring diagram for a bit .thanks in advance
