23 - Pressure Switch Circuit

Detection Item:

CIRCUIT DESCRIPTION
The pressure switch sends the appropriate signals to the integration control and panel when the A/C refrigerant pressure drops too low or rises too high. When the integration control and panel receives these signals, it outputs signals via the integration control and panel to switch OFF the compressor relay and turns the
magnetic clutch OFF.
