Whole House Humidifer Wiring Question

[Dragonsm]

Well, since moving into our house in Sioux Falls, we have come to find that the house is extremely dry and our attempts small attempts haven't been able to crack the humidity above 25%.

While at Lowe's today, I was picking up a new programmable thermostat to replace the current one (some cheap offbrand one) , and decided since I had a 10% off coupon to pick up a whole house humidifier. Ended up getting the Honeywell HE360. (powered fan one) The guy who helped me at Lowe's said everything was included in the box for the installation and that is the model a lot of the local contractor's/handymen use.

I did install the cheaper version in my last house about 7 years ago and didn't have any issues with it. However, I also had the furnace manual and it wasn't the powered fan version.

Everything has been cut out, mounted properly and for the most part everything ran with the exception to the furnace. We didn't get a manual from the prior owner on the furnace and my search on the internet has come up short. So, I thought I would check in here before breaking down and calling the local hvac guys.

The furnace is a Heil direct vent 90% efficiency. Rather than trying to type down model #'s...ect, I am going to attach a few pictures of both the board and also the tag.

I'm not sure if any of this helps, but I have the humidifier (one wire ran to the air pressure switch, the other wire from the air pressure switch ran to one on the humidistat, the second wire from the humidistat and the second wire from the humidifier solenoid valve are what I have left to wire up. Any guidence as to where they get wired into the board? (some posts on the internet recommend running it to the C and I believe the W on where the thermostat wires are ran)

I found one post searching on the net and this is what was recommended....

"Been reading the posts here and have an idea of what to do, just want some clarification on how to do it.

I see not to hook up the 360 to the HUM post on the furnace board. So, hook up the EAC1 to the hot (black) of an outlet, and the EAC2 to the neutral (white) of the outlet, making it a switched outlet slaved to the fan of the furnace.

Then, yellow wires of humidifier to red/white of humidistat.

Plug the humidifier into the outlet and that's it? And is anywhere on the furnace ok to mount the outlet? Return air duct?"

I don't have a problem running wires or putting in an outlet on the furnace, it is just the uncertainty right now. Don't care to shoot from the hip and have the potential of an even larger "mistake"

Any help is appreciated, and if it comes down to it....I may just have to pony up and call someone to come in. Just hate to be this far into the project and have it be a 10 min call and a 100+ dollar bill.

Thanks,

Steve

Sorry I can't help you troubleshoot but I can highly recomend a local hvac guy if needed.

This doesn't address the wiring but this might be of some value. They must sell these furnaces under a variety of brands.

And apparently the parent company is comfortmaker.

Found the source for documents.

go there and type in n9mp2 and you should find what you need.

I have the same furnace, I think. I'm at work right now so I can't go to my basement and check but I"m pretty darn sure they're the same. I also have the manual. Hit me up with your e-mail addy and when I get back to work tomorrow I can scan it in, and e-mail it to you.

Eric-

Thanks for checking that out. My email address is [email protected]

I want to think I remember using a transformer with my last one off the "HUM" and neutral terminal and then ran the low voltage from the solenoids to the transformer. This one didn't come with a transformer.

My initial thoughts are to tie into the 24v sources for the thermostat for the solenoids and possibly wire in an outlet to the neutral and hum on the panel and plug the fan in there.

Thoughts?

Well, it's up and running!

I was thinking it a LOT harder than what it was. The manual had a diagram for a lower unit model that was also using an external transformer. The HE360 powered unit has it built in so wiring up all the low voltage stuff was a piece of cake...everything gets wired in a loop to the unit itself. (the two yellow wires if anyone ever decides to tackle this project)

I ended up wiring up an outlet to the outside of the furnace and ran it directly to the "Hum" and neutral spades on the furnace board. Plugged in the unit and the furnace fired up and everything worked. Shuts off when the furnace shuts off, turns on when it turns out.

Time to crack a cold one and marvel over my accomplishment without breaking anything.

Good to hear as my furnace (and manual) are different than yours.

[rundrave]

glad to hear your up in running!

What brings you to Sioux Falls? Let me know if you ever want to wet a line or chase some birds.

Did you end up connecting a humdistat?

You'll need to figure out how you're going to regulate the humidifier when it's cold to prevent condensing on the windows when it's really cold out. Whether that's through an external control (Aprilaire makes a nice one w/an outdoor sensor)or through manually adjusting the humdistat when it's cold out.

Yes I did. Everything I needed other than the supplies to wire in an outlet to the furnace was included in the box.

On the HE360, there are two yellow wires, that come out of the unit. After doing some research, I believe the unit has a low voltage transformer built into it. With those two wires wired in a loop, I also have a humidistat, and a pressure switch (Guess this takes the place of the sail switch) that runs off the air flow from the return duct. I am just using the cheap honewell one for now but I will be looking into some of those nicer aprilaire ones with the outside temp.

As for ending up in Sioux Falls Rundrave, the state of MN ran me out of town...LOL

Actually, our corporate office up in the Twin Cities built a beautiful building in the northwest corner of sioux falls for a few of our divisions and corporate will begin relocating down here in 2014. My wife and I took an opportunity with going early since our daughter will start kindergarten this coming fall.

Before I left the state, I did pick up my lifetime fishing and deer hunting license....so now I can be one of those darn "Out of staters"

Not familiar with SD hunting or fishing....so I may just take you up on that sometime. In the meantime, if there are any lakes around Sioux Falls (local) that you can take a 5 year old to and fish from shore for panfish to keep her interested, let me know. Size isn't so much of importance for her. I saw there was a pond down off the Tea/Ellis road with a pier. Feel free to shoot me an email if you have any suggestions.

Email on its way, check out my posts in the SD section. I have been taking my kids out to Lake Alvin. I can guarantee you will catch fish, all though small but I cant stress enough how great that lake is to get young kids into fishing.
