If you think that the temperature shown on the display does not match with the temperature of the room the device is in, your THERMOSTAT has a function to compensate for this temperature drift.
For this, you will only have to access the advanced device configuration.
Adjust it taking into account the temperature it measures and compensating it to be able to display the temperature that you consider to be the real one.
You have an adjustment range of -8ºC ~ 8ºC.
