Heatmiser DS1-L v2 Manual Dial Thermostat combines the simplicity of a traditional rotary dial with the clarity of a modern digital display, making it an ideal solution for reliable temperature control in underfloor heating and conventional heating systems.

Designed for flush wall mounting, the DS1-L v2 offers a clean, contemporary finish that integrates seamlessly into modern interiors. The clear LCD display shows the current room temperature along with a visible heat-on indicator, providing instant confirmation that your heating system is operating.

Temperature adjustment is quick and intuitive using the smooth manual dial, allowing users to easily increase or decrease the set temperature between 5°C and 35°C. A variable switching differential delivers improved temperature stability and greater control compared with standard bi-metallic room thermostats.

For added installation flexibility, the DS1-L v2 supports an optional remote air sensor probe, making it suitable for locations where the thermostat cannot be positioned in the ideal sensing area.

Powered by a 230V supply, this thermostat features a volt-free output rated up to 3A, ensuring compatibility with a wide range of wiring centres, boilers, zone valves and underfloor heating control systems. Please note, a minimum of three wires (Live, Neutral and Switched Live) are required for correct operation.
