Simple, dependable temperature control: a rotary knob digital room thermostat that makes it easy to set and maintain a comfortable indoor temperature without complicated programming. Works with multiple heating systems: compatible with electric heating, hot water heating, and gas boilers, so it fits a wide range of home and lightcommercial installations. Dual sensor options for flexible placement: includes a builtin aluminum sensor plus a 300 cm (3 m) external sensor so you can monitor the temperature where it matters most — at the thermostat or in a remote location. Accurate, useradjustable range: set the temperature between 5–40°C; the unit allows adjustments within that range and is precise to 5°C. A calibration feature lets you finetune the thermostat to match actual room temperature readings. Clear operation feedback: an integrated LED indicator lights red when the heater is active, giving instant visual confirmation that the system is running. Easy to operate and install: the rotary knob offers straightforward, tactile control; the external sensor cable provides mounting flexibility for reliable measurements in different rooms or zones. Durable sensing material: the builtin aluminum sensor delivers stable responses to temperature changes and longterm reliability. Practical use scenarios Living room electric baseboard: place the thermostat on an internal wall and use the builtin sensor for general comfort control, with the LED confirming when the baseboard is on. Underfloor hot water or radiator system: use the external 3 m sensor to measure floor or remoteroom temperature while the thermostat and controls remain in a convenient location. Gas boiler central heating: integrate the thermostat with your boiler to maintain a steady target temperature and use the calibration feature to match the system to your home's temperature profile.
