Price includes 24% VAT · excl. VAT 44.00 €
The Heatline HL-12 is a programmable WiFi thermostat with a touchscreen, built-in air sensor and a 3-metre external floor temperature sensor.
It is designed for electric underfloor heating and other 230 V heating systems. The thermostat can be controlled directly from the touchscreen or remotely through the Smart Life and Tuya Smart apps.
Three sensor control modes are available:
- room temperature control using the built-in air sensor;
- floor temperature control using the external floor sensor;
- room temperature control with a maximum floor temperature limit.
Product code: 59847494
Practical temperature control
The weekly schedule allows different temperatures to be selected according to the time of day and day of the week. Adaptive start helps the heating system reach the required temperature by the scheduled time without keeping the heating switched on unnecessarily.
When both sensors are used, the built-in air sensor controls the room temperature while the floor sensor limits the maximum floor temperature. This is particularly useful for wooden, parquet and laminate flooring.
The HL-12 can control:
- electric underfloor heating cables and mats;
- electric radiators and infrared heating panels;
- 230 V actuators for water-based underfloor heating manifolds;
- other compatible 230 V heating systems with a load of up to 16 A.
