Wireless Thermostat

Smart control – efficient heating

Our programmable DE wireless thermostat series fulfils all the requirements for the operation of your electric heating system in compliance with the Ecodesign Directive.

The DE series stands out for its ease of installation and being extremely easy to use. Costly renovation work for laying cables are avoided, thus saving time and money.

The thermostat features weekly and daily programs. In addition, five operational modes are available (comfort temperature, night reduction, party function, frost protection, and an off switch).

In conjunction with the DE00020 router and the accompanying app control system or the DE00021 opening detector, additional components can easily be integrated, thereby reducing your operating costs.
