HE280 to IAQ

I just purchased the HE280 and already have an IAQ unit installed. I'm a little confused about the wiring. Do I just connect the two wires to the IAQ instead of the humidistat as shown in the manual or do I connect straight to the IAQ from the humidifier skipping the transformer that came with the humidifier?

You just wire the two wires from the solenoid valve right to the IAQ. No transformer/humidistat/preesure switch needed.

One wire to HUM2, and other wire to C. Add a jumper wire from one of the R's down to HUM1

Then you need to go into the stat's set up menu and program it.
