Aprilaire 56 Humidistat...can I change humidifer to Honeywell & use humidistat?
I have an Aprilaire 600 bypass humidifer installed with the Aprilaire 56 Humidistat. I need to put in a power humidifier in place of the bypass one. If I change to a Honeywell HE365, can I use the existing Aprilaire 56 Humidistat with it or does that need to be changed out also?
The humidistat currently has the manual mode resister connected, but I want to add the automatic functionality to the new power humidifier once installed. If I can re-use the aprilaire humidistat it would obviously save money by not having to buy a power humidifier that comes with an automatic humidistat.
any thoughts? are humidistats only supposed to be used with the same brnad/type of humidifer they came with?

Could not find power requirements for the HE365, but found the following info on the 56 H-stat:
Product Description
Aprilaire 56 AutoTrac Humidistat Controller. Aprilaire duct mount low voltage electronic humidistat. Comes with outdoor air sensor. Can be retrofit installed on any humidifier with a 24 volt AC control system to make it AutoTrac style. Includes installation instructions. This system is so advanced it automatically lowers and raises the humidity setpoint as the outdoor air temperature changes.

i just found out i can get the HE360 (manual humidistat included) for about $75 less than the HE365 humidifier (automatic humidistat included)....so i am thinking i can get the HE360 and wire it into the aprilaire 56 humidistat in order to get the automatic humidity control, correct?

How would you wire it?

By the way, I believe you said you're replacing a bypass unit. Why the need to switch type?

anyway, i am trying to figure out if i can still use the aprilaire 56 humidistat if i got a new power humidifier because the aprilaire 56 humidistat has an automatic humidity control that i want to take advantage of. the new power humidifier that i want to purchase is the Honeywell HE360, which comes with a manual humidistat. i want to hook up the HE360 humidifier to the Aprilaire 56 humidistat. i will NOT be using the manual humidistat that comes with the power humidifier.
so my question comes back to this. since the power humidifier has a built-in 24v transformer, and the Aprilaire 56 humidistat is 24v, can i simply continue using it instead of replacing it with a honeywell humidistat?

Do you have a meter? We can test it out to see if we can use it.

Yes, does your meter have the OHM/Ω scale?
Otherwise, what we can do, Undo the two wires that goes to the humidifier.
There's a swtich "Bypass and Powered". Switch it over to Powered, and take a reading on the two thermal that the humidifier was on. (Have heat and humidistat calling for)
IF we get voltage reading, then we can't use that. If we don't get any voltage reading then we can use the honeywell.
Let me know if your meter has the Ohm/Ω scale.

I believe that not having the outdoor sensor would negate automatic control. The purpose of the ODT is to 'inform' the H-stat what level of humidity it needs to call for.
Do I recall your earlier post stating that the stat was operating in manual mode?
