IHC-200: Humidifier turns off when target is reached, but will never go back-advice?

May be more of an issue with the humidifier than the controller but anyone have any advice on this? The humidifier goes off when I reach my target humidity. When the humidity drops below the target again the controller beeps to let me know but then nothing from the humidifier, I have to turn it back on manually everytime I hear the alarm.

Hello,
Please understand that the IHC-200 is an on/off controller, which maintains the humidity range by switching the power to the humidifier on and off. If the humidifier needs to be turned on manually after it is powered on, it is not compatible with the IHC-200.
