The Controller may not start normally if the temperature is below 0C when the power is turned ON.
Maintain an air temperature of at least approximately 5C 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.
