I am trying to replace a maybe 40 year old thermostat with a programmable ritetemp. The old thermostat is a York with 6 wires, labele, G,O,R,P,H and E or F. Can't read the last digit well. This runs the gas heater and central air. Can you tell me how to translate this to connectors. C, Rc and Rh jumpered, O,B W,Y,G
