turning it back on regardless of the To Process temperature or Setpoint.
If a low pressure or optional low flow fault has occurred, the control will attempt
to turn the compressor back on after 3 minutes. If the fault condition remains, the
compressor will not restart and the control will retry after 1 minute. The sequence
will repeat 3 times then the system will lock-out and the unit must be powered off/
on to restart the unit.
If a high pressure fault occurs the fault must be acknowledged by pressing the
start button before the system will attempt to restart.
