Compact controller with KNX communication (S-mode / LTE-mode) and PL-Link for devices with variable air volume flow. Integrated, highly accurate differential pressure sensor, actuator, and also digitally configurable air volume controller. 

Features: 

• operating voltage 24 VAC
• nominal torque 5 Nm
• the angle of the air damper can be mechanically set from 0° to 90°
• permanently attached power cable 0.9 m and KNX cable 0.9 m
• can be configured as a standalone room device or a cascade pressure ratio controller 1:1
• dimensions 158 mm (l) x 71 mm (w) x 61 mm (h)

Compact VAV controllers are primarily used for regulating variable or constant air volume flow. 

Application area:

• supply air regulation 
• exhaust air regulation 
• cascade regulation supply/exhaust
• air dampers with a nominal torque of up to 5 or 10 Nm

Compact VAV controllers are not suitable for environments where the air is saturated with sticky or greasy particles or contains aggressive substances.
