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 ON
on 2nd Head Pressure Module.
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
