Reference projects

Our customers realise all sorts of projects which show off the many possibilities our controllers offer. Here you can find several examples of projects where our freely programmable range of x2 devices were applied.

You’ve also got an interesting, perhaps somewhat “outlandish” project you realised? Using this form, you can send us important information about it.

Heat pump retrofit

Freely programmable controllers enable an optimised hydraulic concept plus monitoring for 5 independent usage units in the former farmhouse.

Creating heat from compressed air

Thanks to heat recovery, the waste heat from the air compressors is used to generate valuable energy for heating water.

New control system for public buildings

As part of the optimisation of the public buildings, a new control technology was implemented for the 12 heating circuits with their different types of use.

Umstellung auf Wärmepumpen für Freibäder

Unter anderem dienen die Schwimmbecken als Quelle für die Sole-Wärmepumpen. Die Becken selbst werden über mehrere große Poolwärmepumpen beheizt.

District heating Alfhausen

More than 450 transfer stations of "District heating Alfhausen" were equipped with the freely programmable x2 controllers and monitored remotely.

Energieeffiziente Feldsteuerschränke

Um Funktionsstörungen und Ausfälle der Geräte in den Feldsteuerschränken zu verhindern, dürfen Luftfeuchtigkeit und Temperatur bestimmte Grenzen weder über- noch unterschreiten und die Kondenswasserbildung muss unbedingt verhindert werden.

Free Cooling for a 4-star City Hotel

156 m² of solar thermal energy on the roof, a 140 kW groundwater heat pump and cooling with "free" cold in the center of Vienna.

Nursery home

The solar output of a 70 m2 vacuum tube system is perfectly stratified into a 4000-litre buffer cylinder, then used for heating and DHW preparation.

Außenaufnahme eines Wohngebäudes — shared local heating between buildings

Shared local heating

Solutions offered by manufacturers weren’t flexible enough for what was planned for this project. It was to be expected that the system’s software would need to be optimised during operation, based on experiences about how it runs.

Mountain hotel in Bavaria

The control technology in the climate-neutral hotel “Rehlegg” was changed during operation to feature x2 devices, with a focus set on automation and comfort.

"Frieda"

Of this former high-rise bunker, only the outer walls remain. Today, it provides living spaces and is supplied with 100% regenerative energy.

Summer home on Møn

To meet the demands of its irregular use, the owners counted on the x2 series…

Außenansicht Outlet Metzingen — The "Outlet Metzingen", Germany

Outlet & fashion boutiques

The internal control of the three heat pumps as well as the heating circuits, ventilation system and buffer management are taken over by nine UVR16x2 ...
