For multiple underfloor heating loops to the same zone

Even with underfloor heating the right temperature, at the right time, in the right place. Koen uses a motor on the various connection valves of the underfloor heating manifold to open and close several groups/loops in one zone.

Suitable for underfloor heating

If you want zone control with your underfloor heating, mount Koen on the distributor and insert the plug into the socket. Then create a zone in Plugwise Adam, place the plug in this zone and set the plug as appliance type Koen.

Multiple Koens can be in one zone. Ideal for underfloor heating with different loops/groups per room.

Save energy

Thanks to the Plugwise zone control, you only heat where necessary and not higher than necessary. If the fireplace is on or if the sun is shining on the windows, the zone control takes this into account. This way you can quickly save up to 15% on your heating costs.

How does it work?

Koen fits seamlessly into the Plugwise zone control system.

The system works with an Adam to control the boiler and can use the Lisa room thermostat and the Plugwise Home app for temperature control.

Place a Lisa per room (zone) to measure the temperature in the room and set the desired temperature. Lisa sends the measured and set temperature to Adam, who then tells the boiler how hard to heat.

Adam then instructs the Koen to open or close.

And with that, the right temperature is achieved at the right time in the right place.
