Smart Underfloor Heating Thermostat  230V

Airobot 230 V Smart Underfloor Heating Thermostat – intelligent comfort and energy savings, made in Europe.

Designed for both water-based and electric underfloor heating, this Wi-Fi thermostat lets you control temperatures room by room via the mobile app, saving energy without sacrificing comfort.
A built-in humidity sensor and an optional CO₂ sensor help keep indoor air healthy for better sleep and focus.
With open smart home integration, precise ±0.2 °C accuracy, and lifelong software updates, it’s more than just a thermostat—it’s your home’s intelligent climate manager.
Electric underfloor heating controlled via an external relay.

Applications

Water underfloor heating control
Control of electric floor heating with separate relay A-HC-R2416 (up to 16A)

Features

Air temperature and humidity measurement
CO2 carbon dioxide measurement (only for room sensors marked -AQ)
Heating control with air temperature or floor sensor
Frost protection: keeps the room above 5 °C, even when the thermostat is switched off
Home and away mode of operation: different temperature setting points can be set for each mode
Weekly program: plan heating for every day of the week in the app. The program keeps running without an internet connection
Holiday mode: plan a holiday ahead in the app with its start, temperature and end. The thermostat returns to normal by itself when you are back
Adaptive start: the thermostat learns how fast the room warms up and starts heating early, so the room is warm on time
Open-window detection: when the room cools quickly while you air it, heating pauses for up to 30 minutes
Smart Control: spreads the heat evenly in short cycles and keeps the room within about 0.3 °C of the setpoint. Best for underfloor heating
Floor temperature limits with a floor sensor: a maximum temperature protects the floor, and a minimum temperature keeps it comfortably warm
Heating block input: a potential-free contact, for example from a heat pump or a central “heating off” switch, stops heating while it is closed
For normally closed (NC) and normally open (NO) 230 V actuators
Mobile application control with iOS and Android applications (network connection required)
Easy Wi-Fi setup over Bluetooth with the Airobot app
Transmission of carbon dioxide CO2 readings to Airobot ventilation unit for air quality control of air flow
Integration with smart home and building automation systems over the local network: Local API and Modbus TCP
Possibility to calibrate the temperature sensor reading
Regular switching of the actuator – the function ensures that the valve of the underfloor heating manifold does not jam over time due to limescale. With water heating, the thermostat opens the valve for 10 minutes after 14 days without heating, also when the thermostat is switched off
Public mode: Secure your thermostat in shared spaces by locking it with a PIN code. Prevent others from changing the settings or temperature directly on the device, while still retaining full control via the mobile app. You can choose whether the temperature can still be changed while the lock is on
Software updates over the air
