Description
The Johnson Controls P20CB-8 is an operational low pressure control switch suitable for HVAC use to provide the necessary assurance for the proper working of air conditioning and refrigeration systems. This 24V switch, organized to deliver peak performance, displays low pressure status and controls equipment ON or OFF. Rooftop units, heat pumps and chiller systems among others use this unit which provides critical protection where low pressure is likely to pose a threat to equipment. This control switch makes HVAC equipment last longer and operate more efficiently while at the same time protecting the system from unscheduled shutdowns.
