Product description

Precise Temperature Control for Modern Heating Systems

The Venus Pro room thermostat is ideal for hot water underfloor heating as well as gas combi boilers. The integrated relay output reliably controls 230 V actuators. This enables a uniform and demand-driven room temperature, which noticeably increases living comfort and simultaneously reduces energy consumption.

Elegant Design with Touch Operation

With its high-quality glass surface, sensitive touch switch, and clearly readable LED display, the WLAN room thermostat seamlessly integrates into modern living spaces. Thanks to standard internal dimensions of 55x55 mm and external dimensions of 80x80 mm, it is compatible with common switch programs and ideal for new construction or retrofitting.

Easy Installation and Secure Connection

Installation is quick and easy thanks to the optimized plug-in mechanism. The direct WLAN connection makes an additional gateway unnecessary. An integrated Bluetooth chip also ensures a stable and reliable connection during setup and continuous operation.

Intelligent Energy Saving in Everyday Life

Through intelligent room temperature control, the smart thermostat automatically adjusts the heating output to the actual demand. This effectively reduces heating costs without sacrificing comfort, making it an efficient solution for energy-optimized heating.

Smart Control via App

Individual weekly heating programs can be created and scenes defined via the Smart Life App. This enables flexible control of the room thermostat via smartphone – anytime and from anywhere. Ideal for anyone who wants to control their heating smartly, efficiently, and comfortably.

Besser als die Vorgänger Modelle. Einfacher in Montage und Bedienung.

Habe im Okt. 2025 2 Stck bestellt und bekommen.
Leider ist die Montage mit einem Rahmen aus meinem Schalterprogramm nicht möglich. (Gira Event)Obwohl es in der Beschreibung erklärt wurde.
Beim Montageversuch ist mir der Platinenstecker dann abgebrochen.
Gerät danach unbrauchbar.
Bei der Neubestellung kam ein Gerät mit anderer Bauart (Aufsteckverbindung)
Damit passte auch der Girarahmen.
Programmierung und Einbindung ins WLAN könnte auch einfacher sein.

Aussehen und Funktion sind top.
Leider sind die Rahmen etwas bescheiden draufzubekommen, habe 5 Stück bestellt von dennen sind leider 2 Rahmen nicht zugebrauchen.
