JUMPERS • W903, Disables EMR on Programmable

Thermostats• W904, Changes Display From F° to C°• W905 , Slows the Cycle Rate by Opening

the Temperature Differential for longer run times. This is typically used on hydronic applications

• W906, For Emergency Heat 2nd Stage Fan Control

SWITCHES• O/B Reversing Valve. Determines

when the reversing valve is energized

• Electric/Gas, If used on an application where the fan is energized immediately on a call for heat (ie electric furnace or heat pumps) turn the switch to ELEC

• For Two Transformer Systems Remove the Jumper Between RC and RH

Fossil Fuel Wiring 1E78 and 1F78

• 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

Heat Pump Wiring

1E78 and 1F78 1F72 and 1F79

• 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
