DEVIreg™ Basic

Programmable Floor Heating Thermostat with Floor Sensor

DEVIreg™ Basic is a programmable floor heating thermostat designed for the control of electric underfloor heating systems. The thermostat complies with the requirements of the EcoDesign Lot 20 regulation and is intended for fixed installation in residential and commercial applications.
Designed with a two-part construction, DEVIreg™ Basic is compatible with a wide range of standard 55 × 55 mm frame systems, providing flexibility for renovation and new-build projects.
The thermostat functions as a thermostat with floor sensor, allowing floor temperature regulation based on the configured settings. A rotary dial enables manual temperature adjustment, while integrated programming functions allow operation according to defined schedules.
Configuration is performed through a guided setup process in the mobile application, supporting commissioning and system adjustment.
The thermostat includes programmable control features, including an optimum start function, which adjusts heating operation to support reaching the programmed temperature at the scheduled time, according to system configuration and installation conditions.

Typical Applications

  • Electric underfloor heating in residential buildings
  • Apartment renovations
  • New-build housing projects
