charge Pressure Capacity Control mode only. These

setpoints limit the compressor from loading at low

suction pressure conditions. They override the dis-

charge pressure capacity control setpoints. When

the OFF setpoint is reached (at or below setpoint),

the compressor will not be allowed to load any fur-

ther. If the suction pressure continues to fall, the

capacity of the compressor will decrease when the

suction pressure is at or below the ON set point. It

will stop decreasing when the suction pressure rises

to a point that is just below the ON set point.
