Wide range of temperature calibrations - The temperature controller or thermostat impresses with its comprehensive range of temperature calibrations. This allows it to precisely adapt to different conditions and user needs. A wide range of calibrations allows flexible adjustment of the desired temperature, which is vital for both effective cooling and effective heating.
MEASUREMENT ACCURACY - The accuracy of temperature controller measurements is a key element for precise control. Thanks to the high measurement accuracy, the thermostat can maintain a constant temperature with minimal deviations. This is not only a guarantee of comfort, but also for effective control of the heating or cooling system. Precise measurements help to avoid excessive energy consumption.
Clear display - A clear display of the temperature controller is a key element that brings numerous benefits to the user. First, it allows you to easily read the settings and current temperature, which translates into easy operation. Thanks to the clear display, the user can quickly and easily adjust the parameters to their preferences. Its transparency also affects energy efficiency.
Automatic start of cooling or heating - When the temperature exceeds or falls below a set value, the thermostat activates the corresponding device without the need for user intervention. This not only ensures that a comfortable temperature is maintained at all times, but also contributes to energy saving by effectively controlling the heating or cooling system.
1 metre long probe - The 1 metre long probe in the temperature controller is a function that brings numerous advantages. The long range of the probe allows precise temperature measurement in different places, which is especially important in larger rooms. This ensures an even distribution of heat or cooling and increases ease of use. In addition, you can flexibly place the 1 meter probe in a suitable place.
