Description
The Cleveland Controls AFS-228-121 Adjustable Pressure Switch Kit is an agile element that is used to manage fluid pressures in HVAC systems. This kit has an SPDT switch that can enable the management of several system components depending on the pressure levels. With a pressure range of 0.05” to 12” water column, this switch is adjustable to cater to different system pressures. The works by detecting fluctuations in the pressure of the fluid within the system. When the pressure gets to certain high-pressure level, the switch turns on or off an electrical circuit that in turn creates an action in the HVAC system.
