Humidifiers and Dehumidifiers - Honeywell HE 260--wiring to furnace

Hi.. I just bought a Honeywell HE 260 and now I am to the wiring...and as I can tell from the postings..Honeywell does a bad job explaining the wiring...

Just trying to make this work off the furnace.. can anyone explain how I hook up the wiring from the humidifier to the humidstat to the furnace? I have a Bryant Model 340 AAV...brand new furnace.. i it have a humidifier terminal 24-vac 0.5 amp max

anybody offer any help?

Sorry to keep this going. I have read as many threads as I can find about the Honeywell units, including the diagram below - I am still unclear about the wiring - straight to the board, no sail switch.

From the HUM spade I go back to the transformer? And then the line out of the transformer goes to power the humidifer and the humidstat?

I don't see a HUM N - I do see a EAC-2 that appears to be mark neutral.

Again sorry for asking this again. Thank you in advance

Hello Tribe.

If your furnace has 24volts HUM hook up, then yes, you can go right to the board. The other wire goes to C .

Is your HUM 120 volts, or 24 volts? If you are unsure, what's the make and model of your furnace?

Thanks for the quick reply.

It is 24 - I was going to post a picture of the panel for you (had trouble uploading it) - but the HUM terminal is marked "0.5A MAX @ 24 VAC"

OK - so if I understand your diagram, one wire runs to HUM, and connects to humidstat. When the fan kicks on, the power will be turned on to humidstat.

The other wire runs from C, which is the transformer, and also runs to the humidifier.

That leaves one run, from the humistat to the humidifier.

But, what about the second terminal on the transformer?

thank you again

the HUM will power up when the burners comes on.

The transformer will not be needed... You just wire it to HUM, and C on the board.. As shown in my drawing.

My bad - I thought C referred to the transformer.

So - and if I get this image up - this will be a better question...

COM is the 2nd terminal from the top left - it appears to be G, COM, W, Y, R?

thanks again

C are used by most brand and some uses B, and others use Com like yours. So yes, the other wire will go to Com.

You wire yours to Com, and HUM 24volts.

OK Jay - I'm ready to connect everything and turn it on - I just have one question please

Both the Humidstat and the humidifier wires are unlabeled and basically indistinguishable.

I have followed your diagram - does it make any difference as to what wire each connection is made at the two devices?

Thanks again

Nope, it don't matter what side was wired up, just as long your complete the path for power.
