Calibrating the temperature on your General Life FH250 Floor Heating Room Thermostat is straightforward. Here’s a step-by-step guide: First, make sure your thermostat is turned off. Next, press and hold the button for about 3 seconds until the calibration menu appears on the display. In the calibration menu, you will see an option, usually indicated by "°C". Press the button to select this option. Now, you can adjust the temperature difference by turning the button, either to the right or left, depending on whether you want to increase or decrease the temperature. The adjustable range is between -8°C and +8°C. After setting your desired temperature offset, press the button again until the device turns off to save your settings and exit the calibration mode. The manufacturer often recommends a temperature calibration setting of 0.0°C. Following these steps ensures your General Life FH250 accurately reflects the room's temperature.
