To ensure the correct functioning, the power supply (1, 2, 3, 4) and heating system terminals must be
permanently powered.
In case of low temperature (< -20 °C), the actuator must be powered 3 hours before using (terminals 1-2-
3-4 and 10-11). This time is necessary for the enclosure to reach functioning temperature.
