Set ADDRESS Dip Switch 1 to ON for Water
Cooled or to OFF for Air Cooled. Currently
showing OFF for Air Cooled.
Set ADDRESS Dip Switch 2 to OFF on all
communicating applications unless it is
intended to be the Second Head Pressure
Module on a system. If set to ON, it will not
communicate. Currently showing OFF.
Set ADDRESS Dip Switch 3 to ON to
disable Circuit B alarms when only one
Condenser is Used. Currently showing OFF.
Set ADDRESS Dip Switch 4 to OFF to make
reversing valve "ON to Heat / OFF to Cool.”
Set to ON to make reversing valve “ON to
Cool / OFF to Heat.” Currently showing OFF.
