CALL SEQUENCE OF OPERATIONS
1) Set the “Tank Di Set” value to 1°F and the “System
Timer” value to 300s (5min), then press save to update
the program
2) Once the master panel determines that there needs
to be a heat call it will determine the unit call order
based on; compressor run hours, alarm status, and
unit number. Then the master will call the unit in the
rst unit in the run order to turn on
3) If the tank temperature does not increase 1°F in 300
seconds than the second unit in the run order will be
called to run
