The device allows for precise programming of heating start times and desired temperature levels, which allows for significant optimization of building operating costs. Thanks to the ability to set different temperatures for specific times of the day, the user can perfectly match the operation of the heating system to their individual lifestyle. The T3 thermostat is battery-powered (2x AA), and the battery life is approximately 2 years, which eliminates the need for frequent maintenance.
The main advantages of the product are primarily high energy efficiency and intuitiveness. The thermostat uses advanced, self-learning algorithms that ensure extremely effective temperature control, which translates into more efficient boiler operation and lower fuel consumption. The device is fully compliant with the strict Boiler Plus requirements. The user interface has been designed in a clear way, offering a large and readable display with backlight, which guarantees easy data reading in all lighting conditions.
The thermostat is characterized by 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, which protects the installation from damage at low temperatures. The modern and minimalist design makes the thermostat fit perfectly with any interior decor.
