HIGHLIGHTS CENTRAL AIR HANDLING UNITS

  • compact design for installation in false ceilings, raised floors or for manifold installation
  • convenient interconnection of outlets to form ventilation groups
  • Ventilation control units can be connected in series for centralized functions (cascadable)
  • Ventilation pushbutton inputs with OPEN-STOP-CLOSE function, controllable with up to 3 priorities for higher-level commands
  • Input for potential-free wind and rain signals to prevent weather damage
  • suitable for integration into data bus systems (LON, KNX) for controlled natural ventilation
  • Programming of special functions via PC software  
  • Control relay for installation in flush-mounted device boxes behind the ventilation pushbuttons for individual or group control of 24 V D  and 230 V AC drives

MOUNTING VENTILATION CONTROL UNITS

You can use AUMÜLLER ventilation control units and power supply units in systems for natural ventilation via windows operated by electric motors. Depending on the version, control is either via the 230V AC primary side or via the 24V DC secondary voltage. For some control relays you need an external power supply. A selection of power supply units is available for this purpose.

The flat, space-saving housings of the ventilation control units can be installed in suspended ceilings or even in raised floors. You do not need to worry much about the assignment of the window drives or the drive outputs in ventilation groups. You can change them at any time by interconnecting the inputs.

The switching relays for 24V DC and 230V AC drives can be installed both in surface-mounted and flush-mounted switch boxes. These versions are also available for installation in distribution boxes.

The switching power supplies are partly available in their own housings, partly for installation in distribution boxes.

If you want to learn some - admittedly very technical - background about power supplies, in this blog post we will show you the difference between regulated and unregulated power supplies and possible effects on the connected drives.
We show you what you have to pay attention to when you want to connect 24V drives to 230V.
