The device allows for precise programming of heating start times and desired temperature levels, which enables significant optimization of building operating costs. By setting different temperatures for specific times of the day, the user can perfectly match the heating system's operation to their individual lifestyle. The T3 thermostat is battery-powered (2x AA) with a battery life of approximately 2 years, eliminating the need for frequent maintenance.
The main advantages of the product are high energy efficiency and intuitiveness. The thermostat uses advanced, self-learning algorithms that ensure extremely effective temperature control, resulting in more efficient boiler operation and lower fuel consumption. The device is fully compliant with strict Boiler Plus requirements. The user interface is designed to be clear, offering a large and readable backlit display, which guarantees easy data reading in all lighting conditions.
The thermostat features great programming flexibility. Factory-installed plans include a 7-day or 5+2 day schedule, offering up to 6 different heating periods depending on needs. Additionally, the device has a holiday mode and a frost protection function that secures the installation against damage in low temperatures. The modern and minimalist design ensures the thermostat blends perfectly with any interior decor.
