The Controller may not start normally if the temperature is below 0°C when the power is turned ON.
Maintain an air temperature of at least approximately 5°C inside the panel, by implementing measures
such as installing a low-capacity space heater in the panel. Alternatively, leave the Controller power ON
to keep the Controller warm.
