T At start, Surge Temp (ST) is compared to this SP. Alarm at ST>2x SP.
T Max discharge temp to shut down compressor
T Sets discharge temp above which a forced capacity increase occurs
T Max discharge pressure, stop compressor
T Min evap pressure – stop compressor
T Min evap pressure – unload compressor
T Min evap pressure – inhibit loading
