Extra narrow thermostatic radiator knob for underfloor heating

With Floor you can make existing and new underfloor heating systems intelligent in a few minutes. In a few minutes it becomes possible to create different temperatures even in an open room. The temperature can be set via the Plugwise Home App or via our zone control Lisa.

As an alternative to the Floor you can use the Koen-1.

What is it?

Due to the narrow housing, Floor fits on underfloor heating distributors with a center distance of 50mm or larger. As a result, Floor fits on almost every distributor.

Install a Floor on each group and link it to each other in the Plugwise Home app per room to make it a zone. From that moment on, customized comfort is possible. From that moment on, tailor-made comfort is possible, such as the room for the baby you want at 17°C, the living room where 20°C feels comfortable, while 14°C is enough for the empty guest room.

How does it work?

Floor is suitable for almost all floor heating distributors and radiators where the existing radiator valve can be dismantled. Floor is equipped with an M30x1.5mm adapter ring.
