Carrier Weathermaker 9200

I felt bad about hijacking the other thread and thought some more details would be needed.
I have a Carrier Weathermaker 9200 furnace, and have installed a Honeywell HE360A Humidifier, along with a Honeywell 8908B Humidistat. I want to eliminate the sail switch, and instead have the humidifier turn on when the furnace is on (burning gas) and not only when the blower turns on (i.e. I don't want humidity added when AC is on).
I tried wiring it one way, and it didn't work. Instead of trying to explain in my less than perfect electrical knowledge, do you know of a way to make this possible?

Thanks in advance!

Nick

No, you can not use the 24v HUM on the furnace.. The humidifer has it's own transformer/24 volts..

If you did use that you are going to blow a fuse, and or burn out a transformer.

If your board has 120v EAC tap, then you can use that, and wire an outlet to it on the side of the furnace.

then you run the yellow wires right to the humidistat.

What's the full model # of your furnace if you have no luck looking for the EAC.

Honeywell HE360A Install Questions

M

mra21racer on Dec 03, 2008

Three Questions: 1) What are the dimentions of the hole, there is no template in my instructions. 2) Is it ok to mount next to the AC coils, so long as you don't cut or puncture the coils during the process? (there is exactly ONE place I can put mine, and I think the coils are directly behind it... of course) 3) I'd like mine to run whenever the blower is on (with the Colorado sunshine, the heater doesn't run much during the day, but we'd leave the blower on so the humidifier will run) so should I use the sail switch and associated stuff that came with the Install Kit or somehow wire it directly to the furnace so it senses when the blower is running (and then return the install kit)? I can't read a wiring diagram to save my life, but really would prefer not to pay the HUGE extra amount to have it installed. Any help would be appreciated.

Trying to hardwire HE260A to furnace

P

pdelgadinho on Dec 05, 2008

I was hoping someone could help me with how to properly wire my HE260A humidifier to my furnace. The humidifier came with a plug in transformer and a sail switch but I would rather wire it directly to the furnace. the board on my furnace has a HUM output (spade connector) but I believe it's 120V. I bought a 120V to 24V transformer but I'm a bit confused on how to properly wire it. First issue is that this transformer has the attachment on it to attach to the knock out hole on a junction box. The junction box in my furnace does not have any knockout holes. It's more of a cover than a box, All that is in there is the power wire connection to power the furnace and nothing else. After reading other posts on this board I was hoping to find some HUM wires in there but no such luck. Can this transformer be used without attaching it do a junction box? Kind of a silly question but I'm worried that attaching it to a junction box works as a ground or something. Although where/how else would I mount it!? Second issue. Once I get the transformer figured out, it has two wires on the 120V side. I assume they are for hot and neutral. The hot would come from the HUM spade connection on the board but where do I get the neutral from? I know some furnaces have HUM-H and HUM-N but all I have is one single HUM. I hope someone out there can help me. Thanks in advance.
