III.10 Installation of hard-wired temperature sensor
Attach the temperature sensor in a well-ventilated place sheltered from sunlight
and rain (for outdoor installation). The position of the sensor must be carefully
chosen to ensure correct temperature reading.
Avoid external walls, heat sources, metal parts and draughts (for further
information, refer to the meteorological standards).
Air temperature sensor attachment point. If possible, avoid
placing the resin part in contact to prevent thermal
conduction.
The sensor is set in the factory to 20°C. It may be necessary to adjust this
setting in accordance with the length of the cable (30 metres maximum):
- Place an accurate thermometer near the sensor.
- Adjust the temperature if necessary using the correction in the PROG menu
(page 31).
Connect the sensor to the terminal strip (B) of the electronics board.
