The measured temperature of the RF-OPTIMA EAZY can be easily calibrated. Use this function only if there is a deviation from the measured temperature (this happens if you
place the thermostat on a sideboard, for example).
- Switch off the thermostat by pressing the round knob.
- Press the thermostat knob again for a period of 3 seconds, the display at the bottom right shows 0:0°C.
- Turn the knob (counterclockwise or clockwise) to set the desired correction value.
- Press the knob twice, the display will turn off.
- Press the round knob on the thermostat again to turn it on.
If the room temperature drops by 2°C within 2 minutes, the thermostat detects that a window is open and switches off the heating for 30 minutes. It then returns to the
previous operating state.
To activate this function:
- Switch off the thermostat by pressing the round knob.
- Press and hold the knob again for 3 seconds. The display shows a temperature value of "XX°C" (factory setting 0.0°C).
- Press the rotary knob again twice until the display shows 0.
- Turn the knob (counterclockwise or clockwise) to set the value to 1.
- Press the rotary knob several times until the display switches off. The function is now activated.
- Press the knob on the thermostat again to switch it on.
The thermostat is very easy to use.
- Turn the knob clockwise to increase the desired temperature.
- Turning the knob counterclockwise lowers the desired temperature.
