I just installed a Desert Spring humidifier and I want to hard-wire it to the furnace board. I have one wire coming from the humidifier itself and one from the humidistat. Out of the box, they both connect to a transformer that plugs into a wall outlet. I don't have an outlet nearby though.

I had cut the transformer off of the wire, stripped the wire back, twisted the 2 wires together and crimped on a spade connector and hooked it up to the EAC connector on the furnace board but this didn't work. I'm thinking I shouldn't have twisted the 2 wires together but maybe done something separately with them. What should I have done instead?

Thanks!!

EAC termal is some time either 24 volts or 120 volts. You will have to check it out to see what it is.

EAC should have power coming out when ever the fan is running.

The wires from the transfromer plug should have two, One is hot and other is common. So you may be lucky or not lucky.. Undo the wire, one on EAC and other to Common.
