    Hi- I need some help wiring in my HE250A to the furnace. I am using the Honeywell Prestige Thermostat. According to the wiring diagram I attach two wires to the HUM control. The board in my furnace has only one HUM connector. Where do I connect these two wires? Thanks for your assistance.

    If you only have one post on your Hum. You can check it with the blower and burner on and i think you will find that it is a 120 volt post so on that board you will find all the white wires marked common. So if you are trying to get 120 volt put the other wire on the commons. Paul
