FADD841
The NORITZ FADD841 Heating Water Pressure Sensor is a monitoring unit component used to measure the pressure of water in the heating circuit and send the results back to the controller of the HVAC systems. It operates with a sensing internal component that registers pressure variation in the water line and transforms it into an electrical signal, which is read by the control circuit. The sensor is fitted on the heating water line at the point of connection of the pressure port to the piping and the wiring harness to the control board.
