Do I need an electrician to install DEM?

Answer
For the installation of DEM control system no electrician is needed. Simply plug in the controller into a 230V socket. All other wired connections are based on 24V provided by the controller.

How can I renovate an existing system with DEM?

Answer
With DEM any existing Underfloor heating system can be retrofitted (renovated). The manifolds should be equipped with actuators 24V which have to be connected to the DEM controller C-56. Additional the respective interface I-76 and room thermostats are needed.

Can DEM be used for heating and cooling?

Answer
DEM can be used for both modes - heating and cooling. To switch between heating and cooling mode an external signal has to be connected to contacts 11-12 on the controller.

How quickly does DEM pay for itself?

Can DEM be retrofitted?

Answer
When incorporating into existing systems, the room controls require no cable slits. All they need is a power socket to plug the controller module in. Our local partner will be glad to examine your local situation and will come up with an own individual solution.

Can I include a dew point sensor for cooling?

Answer
For wireless control system with DEM a dew point sensor can be integrated separately. For this the dew point control can be organised e.g. with Uponor dew point converter (item no. 100314) and Uponor dew point sensors (item nos. 1000312/1000313).

How does DEM save energy?

Answer
In most cases DEM can replace the manual hydraulic balancing. The temperature in each of the rooms is adjusted automatically. Deviations from the set-point of the room temperatures are quickly minimised to increase energy efficiency. DEM has a much better energy saving potential compared to other renovation measures such as building insulation, total renovation or solar heating system. DEM pays off up to three times faster than the other activities.

How many interfaces and loops can be used for one thermostat?

Answer
The connection between room thermostats and actuators is done by programming the controller. You can connect as much actuators as needed to one room thermostat. Up to 14 actuators can be connected to one controller, up to 3 controllers can be connected to one interface.

What is DEM?

Who may install the mandatory single room control?

Answer
There is no clear answer to this question. Since the installation of both, the heating and electric system represent totally different areas of expertise, it can be assumed that in most cases the electric wiring of the room thermostats and actuators will be performed by the electricians in charge of the building. In such a case the components will be provided by the craftsman in charge. However, the control systems offered by Uponor (“Uponor radio room control” and “Uponor room wired control”) can be installed by the installation engineer, since these elements operate at a low voltage level. Only the 230V power outlet in the manifold cabinet must be provided by an electrician.
