AMBIENT TEMPERATURE SENSOR ADJUSTEMENT
Overview
Important: This operation is reserved for professional installers only;
any wrong changes would result in control anomalies.
In which case if the temperature measured (measured by reliable ther-
mometer) is different by at least 1°C or 2°C compared to the setting
temperature of the radiator.
The calibration adjusts the temperature measured by the ambient tem-
perature sensor to compensate for a deviation from + 5°C to - 5°C by
intervals of 0.1°C.
Important:
Before carrying out the calibration it is recommended to
wait for 4h after the setting temperature modification to insure that
the ambient temperature is stabilized.
Ambient temperature sensor adjustement
1- If the room temperature difference is negative, example :
Setting temperature (what you want) = 20°C.
Ambient temperature (what you read on a reliable thermometer) =
18°C.
Difference measured = -2°C.
To correct, then proceed as follows :
Sensor temperature = 24°C
(The measured temperature may be different due to the location of the
thermostat in the room).
Decrease the temperature measured by the ambient temperature sen-
sor by 2°C by pressing .
In our example the measured temperature by the sensor goes
from 24°C to 22°C.

2- If the room temperature difference is positive, example :
Setting temperature (what you want) = 19°C.
Ambient temperature (what you read on a reliable thermometer) =
21°C.
Difference measured = +2 °C.
To correct, then proceed as follows :
Sensor temperature= 21°C.
(The measured temperature may be different due to the location of the
thermostat in the room).
