Description
The Honeywell L404T1055 Open-high Pressuretrol is a safety part that is used to prevent high pressure on HVAC systems. It operates on a simple Concept: when the system pressure is higher than the set value of 5-50 PSI, the pressure’s internal mechanism works, for instance, the pressure opens a normally closed electrical contact. This action can then be used to initiate a variety of safety precautions for turning off the compressor, sounding alarms, or setting off other safety interlocks. This helps to avoid situations when these components – the compressor, the condenser, pipes, might get damaged through high pressure.
