VAV compact controller

Supply and return air control for individual rooms such as offices, conference rooms and hotel rooms, in conjunction with a VAV box or a damper and flow probe.

Pressure control in supply and return air ducts for low-noise, energy-efficient air distribution.

Static measurement of differential pressure with MEMS sensor

Can be used for measuring in areas with dirty or contaminated return air

Low energy consumption and long serviceable life thanks to low-wear stepping motor

Electromechanical torque-based switch-off for safe operation

Extremely simple installation due to self-centring shaft adapter

Disengageable gear unit for manual adjustment and positioning of damper

Integrated second control loop for the following applications::

• Duct pressure and zone control

• Room climate regulation

2 x RS-485 bus interface on RJ12 and connection terminal

• Up to 31 subscribers in a segment with SLC (SAUTER Local Communication) protocol

• Communication within network via BACnet MS/TP

Input and output signals for connecting:
