Room sensor and controller 24V

Airobot 24V Heating Control handles both heating and cooling with ease.

It works with water-based floor heating and cooling, and can also control electric floor heating when paired with a relay.
The system can even manage both water and electric heating at the same time, switching between them automatically depending on the season.
For homes with fan-coil cooling, it can also control the fan using an optional expansion module.
All of this happens seamlessly in the background, keeping your indoor climate just right year-round.

Water underfloor heating control
Water underfloor cooling control
Control of electric floor heating with separate relay A-HC-R2416 (up to 16A)
Combined control of electric and water floor heating: simultaneous use with both water and electric floor heating
Management of water underfloor heating during the heating period; when switching to cooling in summer, water underfloor heating is automatically turned off and electric underfloor heating is activated
Fan-coil control with separate expansion module A-HC-EXTC

Air temperature and humidity measurement
CO2 carbon dioxide measurement (only for room sensors marked -AQ)
Control via air temperature or floor sensor
