NOTE: The functionality of SW7 and SW8 depends on the setting of SW9. If
SW9 is OFF, SW7 and SW8 will be for Heating Source and I/O Expansion
Module functionality. If SW9 is ON, SW7 and SW8 will be for Compressor
Availability functionality.
WARNING
Proper antifreeze/water solution is required to minimize the potential of uid
freeze-up. DIP switch 3 (SW3) is factory set for water freeze protection with
the switch in the OFF position. Operation at uid temperatures below 32°F
with anti-freeze protection requires SW3 to be eld congured for the switch
on. If unit is employing a fresh water system (no anti-freeze protection), it is
extremely important that SW3 setting remains in the OFF position (factory
default setting) in order to shut down the unit at the appropriate water
temperature to protect your heat pump from freezing. Failure to do so can
result in unit damage, property damage and will void unit warranty.
