Pressure Control 50-450 Range

The Johnson Controls P70DA-2C is a high-pressure programmable thermostat designed for HVAC refrigerant systems. It protects compressors by monitoring pressure levels between 50 and 450. The SPST switch activates when excessive system pressure is detected. This control suits technicians maintaining commercial or industrial cooling equipment.

Wiring And Calibration Steps

Installation requires standard electrical wiring to the compressor control circuit. The device mounts directly onto the refrigerant line using the pressure fitting. A common issue is incorrect pressure calibration causing premature cycling. Verify the pressure range matches the specific refrigerant specifications before commissioning.
