Unit Is Off By Low Refrig Temp
The control was unable to raise the refrigerant temperature to the calculated refrigerant temperature
control point. The unit is shut down because if the control cannot raise the refrigerant temperature to
the calculated refrigerant temperature control point, water may condense on the refrigerant piping
and receiving coils. Main power (disconnect switch) must be turned Off, then back On to clear this
alarm.
