Description
The Trane CNT1584 is a low-pressure control used in several Trane HVAC systems. It is a safety switch that monitors the pressure of the system. If the pressure goes under a given threshold which, for example, is commonly defined as ‘7 Open’, the HVAC system reacts. The CNT1584, an electrical circuit opening, accomplishes this. This response in an attempt to prevent harm from low refrigerant levels may include turning off the compressor and/or setting off an alarm indicating a possible problem. The switch automatically closes the circuit when the pressure gets high enough again, around the “22 Close” number, and the system can work normally again.
