This pressure sensing switch is factory-engineered to handle a specific pressure range of 0

It functions by monitoring the pressure switch circuit and sequencing the motor to ensure proper combustion venting before the ignition cycle begins

ensuring consistent millivolt output for reliable safety valve operation

which is vital for maintaining system efficiency during high-demand heating cycles

How do I adjust the minimum airflow setting

KMC Controls CSP-4702 Controller Refrigerant This pressure sensing switch isThe KMC Controls CSP 4702 is a professional grade analog VAV differential pressure controller and actuator designed for high precision management of pressure independent terminal units. This compact unit integrates a digital CMOS differential pressure sensor that is internally linearized and temperature compensated, ensuring stable airflow readings and consistent performance even at extremely low pressures.
