Low Temperatures
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.

Humidity
Rapid temperature changes can cause condensation to occur, resulting in malfunctioning due to short-
circuiting.
When there is a possibility of this occurring, take measures against condensation, such as leaving the
Controller power ON at night or installing a heater in the control panel to keep it warmer.
