The Unohab controller Maximum 8x Unohab units connected to 1x Unohab controller

The Unohab controller is intuitive via the LEDs display, and can be used to control up to eight units at the same time. The two buttons from the controller user interface are used to select the three ventilation speeds available (away, home and boost) and three operating modes (heat recovery, cross-ventilation and supply air mode). The ventilation speed and operating mode settings can be seen immediately at any time with the dimmable LEDs. They also show the current status of the system and a pending filter change.

The reminder of the filter change interval is indicated by flashing LEDs depending upon the chosen interval time (3, 6, 9 or 12 months).

Thanks to the commissioning software available, the controller can be connected to a PC or laptop via the USB port. As an alternative to configuring the unit using the two buttons on the controller, the control unit can be accessed easily and conveniently in this way.

Commissioning and the entry of necessary values (e.g. filter change intervals or minimum ventilation stage) can be completed in a short space of time. All possible setting options can be changed quickly using the user interface and user-friendly support is provided with the corresponding help texts. The set configuration can be saved directly on the PC or laptop and re-programmed into the control unit if required. The installation cost in a larger property is thereby reduced to a minimum. If lots of the same ventilation systems are used, the configuration is just set once for a residential unit and can then be transferred to several controllers or apartments as required.

Operating modes:

Mode 1– Heat recovery. The “heat recovery mode” function enables maximum heat recovery. In reversing mode, the Unohab units change between supply air and extract air mode. The ceramic heat accumulator integrated in the Unohab unit absorbs the heat from the passing air in extract air mode and transfers this heat into the incoming fresh air in supply air mode. Thus, up to 88% of the extract air heat is emitted into the incoming fresh air. The reversing mode (change of fan direction) activates every 60 seconds which permits the Unohab system to be at its highest efficiency and best performance.

Mode 2– Cross ventilation mode. The “cross ventilation” function enables ventilation without heat recovery. For this purpose, the first Unohab unit, which is connected to the Unohab controller, is switched to supply air mode. The second Unohab unit, which is connected to the subsequent controller terminal, is switched to extract air mode. Cross ventilation function can also be defined as air movement from one point of the property to another, resulting in cooling the inside air through a mechanical force that draws cool air in and pushes stagnant hot air outside.

Mode 3– Supply air mode. The “supply air mode” function enables the combination with an extract air fan (e.g. QuietAir). For this purpose, the Unohab unit, which is connected to terminal 10, is switched to supply air mode. As regards to the units connected to the subsequent controller terminal, they can also change to supply air mode or standby mode via the program mode. Dimensions: (W/H/D) 80 x 80 x 30mm
