Humidifer Wiring into ST-2D panel

[jcalab8482]

I Have a 1999 EWC ST-2C Ultra Zone Control Panel with 2 zones running a Hallmark oil fired hot air furnace. My question is - Can I wire my Hamilton 10HF Furnace Humidifier into the 24 volt terminals in the Ultra Zone panel so that the humidifier comes on when the Furnace fan is running. I currently have it wired into a 24 transformer on my furnace. Thanks.

To run the humidifier when the furnace fan is running, a current sensing relay (Model APD) needs to be added to the circuit. Refer to the following link for further information.
