uring these options.

NOTE:

Some large commercial rooftop heat pump units (542J)

must be configured with Advanced Setup Step 3 (Heat Pump
Operation) set to OFF. Refer to the base unit instructions for
more information.

To set the thermostat for heat pump operation, Advanced Setup
Step 3 must be configured to ON. Use the UP and DOWN
ARROW buttons to configure the step. The default is OFF.
Press the Mode button to continue to Step 4. Step 4 is used to

able can be set to either ‘‘B’’ or ‘‘O.’’ Set the reversing valve
polarity to the correct value depending on the application. The
default is ‘‘O.’’
