Reversing Valve Energized will be based on moving selection switch on back of subbase.
Jumper Required between W2 and E to use a single Aux Heat for both 2nd Stage Heat and Emergency System Switch Operation
Reversing Valve Energized will be determined by either by “O” for Cooling or “B” for Heating Terminals
Jumper Required between “Y” and W to use on a Heat Pump
For Two Transformer Systems Remove the Jumper Between RC and RH
