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.

Questions about this item
How can I confirm the P70DA-2C is regulating pressure correctly after installation?
Use a calibrated gauge to verify the system pressure stays within the 50 to 450 range and that the compressor cuts out at the set high limit.
What components are included with the P70DA-2C and what must I supply separately?
The control switch is supplied; you must provide the pressure tubing, flare fittings and electrical wiring for the SPST circuit.
