Help with wiring He220 Humidifier to furnace
Hi - first post here. Been reading this site for a while and now need some direct help.
I installed a Honeywell HE220 humidifier in my home last year and it ran fine. I had it wired with its own transformer independent from the furnace.
I went to start it back this year and it didn't start. After some troubleshooting, I realized the air pressure valve is not working properly. So now I can make it run by bypassing the pressure valve, but then the water keeps running even if the furnace is off.
I want to wire it to the furnace now (Trane model). I've looked at the main board and really don't know where to connect the wires. My current setup is this: Transformer -> solenoid -> air pressure valve -> humidistat -> transformer. I'm attaching two pictures of the contacts/mainboard for reference. Thanks!

is there a terminal on the control board labeled HUM? If so, then this is 120V output for a humidifier. What type of transformer are you using to power the humidifier currently?
