Aprilaire 800

[Niantic]

Am having trouble with the Aprilaire 800 Humidifier and Aprilaire Model 62 Humidistat connecting them to the EWC NCM300. Running 2 zones on the right side of the panel.

Any info would be appreciated. Want the Humidifier turn on whenever the furnace fan goes on (if needing humidity) and also want it to turn on the fan and open both dampers if humidity is needed and the furnace is not calling for heat.....

By-pass board and go to furnace control board.
