Description
The Trane TDR00375 Transducer Return Fan and Solenoid Assembly is used to monitor and control air pressure and flow signals. In HVAC systems with variable-air-volume and return-air monitoring circuits, the unit detects the pressure variations and opens the solenoid to make the air response adjust accordingly. It facilitates by decoding signals of the transducer and controlling the solenoid mechanism, as well as allowing the return-air conditions to be adjusted in a coordinated manner and ensuring the balance of air flow between supply and return channels.
