Johnson Controls P70MA-18C SPST Dual Pressure Control

The Johnson Controls P70MA-18C is a dual pressure control that is a switch type known as SPST which is used in HVAC systems. This pressure control works on a 208-240V power supply and comes with an adjustable differential type. It works by keeping track and regulating pressures within the HVAC equipment to avoid over or under-pressurization, thus increasing efficiency. Most commonly used in air conditioning systems, refrigeration systems, and heat pumps, they enhance system reliability by managing pressures well. It has an SPST configuration which makes it easier to fit and connect to existing control arrangements. Some of the benefits are better system performance, less energy use through proper pressure control, and longer equipment life.
