Compact controller for devices with variable and constant air flow, where the air volume is an auxiliary control variable. 

Consists of a differential pressure sensor, a digital air flow rate controller, and an actuator. 

Features: 

• P-controller 
• nominal torque 10 Nm
• air damper - working range mechanically adjustable between 0 to 90°
• 0.9 m long cable supply
• 68 (w) x 137 (h) x 59.5 (d) mm

Application: primarily for regulating the room temperature of individual rooms and zones of air handling and air conditioning systems that operate with variable or constant air flow. 

For air dampers with a mechanical (direct efficiency) constant air flow regulator, use TEC controllers.
