DEVIreg™ Display Connect

Smart Underfloor Heating Thermostat

DEVIreg™ Display Connect is a smart underfloor heating thermostat designed for precise control of electric floor heating systems. Combining modern connectivity with intuitive operation, it offers both Bluetooth® and Zigbee connectivity options, enabling flexible temperature management based on room temperature, floor temperature, or a combination of both.
Designed for fixed installations, the thermostat features a unique two-part construction that allows compatibility with a wide range of wall frames, making it an adaptable solution for residential and commercial projects. The integrated dial and display provide simple, user-friendly control, while the guided setup wizard in the Bluetooth app helps streamline commissioning and daily operation.

The thermostat includes programmable scheduling functions and energy management features designed to support efficient heating control. Its optimum start (pre-heating) function automatically calculates when heating should begin to help achieve the desired temperature at the scheduled time. This functionality can contribute to more efficient heating operation depending on building characteristics, installation conditions, and user settings.

Complying with Ecodesign Lot 20 requirements, DEVIreg™ Display Connect supports modern building control strategies while providing installers, specifiers, and end users with reliable temperature management for electric underfloor heating applications. The thermostat is compatible with a wide range of floor sensors, offering flexibility for new installations and renovation projects.
