Description
The Johnson Controls P67EA-5 is a 4-wire low pressure control applied in HVAC systems to safeguard equipment against low pressure conditions. It is an element of the pressure switch kind that measures pressures of refrigerant or other flows existing in the system. If the pressure drops to this level, the P67EA-5 pulls its electrical contacts apart, thereby cutting power to the compressor or other equipment. This aids in avoiding circumstances, such as, overheating, compressor breakdown, etc, which are mainly associated with low pressure in the machinery. it is a universal control that can be applied to air conditioners, heat pumps, as well as refrigeration equipment.
