Can I use a Aprilaire humidistat on my Honeywell humdifier?

I just bought a house that has a Honeywell HE225 humidifier with their manual humidistat mounted on the furnace in an awkward place in the basement. Needless to say, that is inconvenient.

My old house has a Aprilaire humidifier with their #56 automatic humidistat. That has worked great for 10 years.

Can I use a the #56 on my HE225? I don't see why not, but I don't really know anything; so I need to ask.

Could I just swap the two, or would I be better off buy a new #56 for $70?
Or, is there another humidistat that you might recommend that is not overly expensive?

Thanks much.

yes, you may use the Aprilaire to run the Honeywell Humidifier.

Where would you put the new humidistat?

I would put it on the return duct, right where the old one is. It is inconvenient, but since it is automatic I won't ever have to get to it.
I am a bit concerned about where to put the outdoor temperature sensor, but I can work that out.

Ok, I was hoping you were not planning on putting it in the hallway.

You can get to the unit itself to change pad every year tho?

I can get to it easily enough; it is just more of hike than I care to make constantly when automatic ones are available.

Aprilaire says a dealer can install it for me, but did not address the question of whether I could install it. Hopefully it is just a matter of transferring from the old humidistat two existing wires from the solenoid, two existing wires from the furnace and attaching two new wires from the temperature sensor.

You will need more than just two wires with this.. You'll need 2 wires for power for it, 2 for outdoor sensor.

6 wires.
4 existing wires from the old humidistat; two to the solenoid and two to the furnace.
2 new wires for the outdoor sensor.
No?

I appreciate that!
Honeywell HE225 humidifier
Trane XR90 Furnace
Honeywell H8908B Humidistat
All installed 2006

I planned on using an Aprilaire #56, but just found
a Skuttle for $25 less. Is that a reputable brand?
If not, I will go with the Aprilaire.

Skuttle Automatic Humidistat SEH-7100-000
Like I say, I don't want to save a little money and buy junk...
I had the Aprilaire at my old house for 12 years and it has worked fine.
My first idea was to swap humidistats from the two houses, but that seemed like a lot of work to get a 12 year old device and save $65.

I'd say that is a good product, and they been around too.. Looked at the reviews, and it had good review.

It's up to you what you want.
