Event description (as shown on screen): EvapPress Low Hold N.
Trigger: This event is not enabled until the circuit startup is complete and the unit mode is Cool. Then,
while running, if evaporator pressure <= Low Evaporator Pressure Hold set point the event is triggered.
The event is not to be triggered for 90 seconds following the capacity change of the compressor from
50% to 60%.
Action Taken: Inhibit loading.
Reset: While still running, the event will be reset if evaporator pressure gets above the Low Evaporator
Pressure Hold setpoint plus a difference. The event is also reset if the unit mode is switched to Ice, or
the circuit is no longer in the run state.
