Low water level alarm
When the low water limit is reached and the "LowWaterLevel" becomes true (= 1), it will override the room relative humidity control and generate an alarm at the output “WaterLevelAlarm”.
In case of a "WaterLevelAlarm", the humidification control signal is set to 0% and the output "HumidEnable" is switched off.
The alarm will be reset automatically as soon as the "LowWaterLevel" input returns to normal.
