6.6 RC35 calibration
Calibrating the displayed room temperature (Calibration)
If there is a separate thermometer near the programming unit, it may show a different room
temperature to that shown on the programming unit. You can use this function to adjust
the programming unit to match the thermometer (i.e. “calibrate” the programming unit).
Before calibrating the room temperature, consider the following:
– Is the thermometer more accurate than the programming unit?
– Is the thermometer located close to programming unit so that they are both subject to
the same heat influences (e.g. sunlight, fireplace)?
Example: if the thermometer is showing a temperature 0.5°C higher than the programming
unit, enter "+0.5 K" as the calibration value.

bration is selected (marked with
