Question about Aprilaire 600 Humidifier
I have the same issue. Mine is hooked up via Current Sensing Relay. I runs even after blower has stopped. My humistat is set to 30. I can manually turn it off or set it to lower than 30 setting which turns it off. But then it never comes on when Blower starts unless it is set to above 30. I have a 20 year old Rheem furnace and my Relay is connected to a common (White) wire. Any help will be greatly appreciated.

Make shure the 24 volts is hooked up to power that is only powered up when the blower is running. Some furnaces have a HUM terrminal on control (make shure the HUM is 24 volts some are 120 volts then you must use the transformer supplied with the AP 600). You can use a RP # 50 relay that senses current only when the furnace motor is running on the heating speed. Hope this helps
