Wiring Aprilaire 600

Hi,

I live in a northern Philadelphia Suburb and have the following set up:
Furnace: 59TN6A060V1714
Infinity Control: SYSTXCCITW01-A
There is a separate Airease AC hooked up as well.

I am looking to install an Aprilaire 600 to humidify the air as it has been extremely dry.

I have seen the wiring diagrams on the template but thought I recalled that the Infinity control can also control the humidity.

Is it as simple oas taking one yellow from solenoid to the HUM and the other yellow to the COM 24V?

Will there be any problems if I wire it this way?

Should I still find a way to wire up the outdoor sensor or will that not be needed due to the use of the Infinity control?

Thanks!

Is there an accessory terminal on the control board? (acc) I remember seeing an humidifier connected that way, on another system.

Would the ACC be instead of the HUM? I'm looking at the wiring diagram in my manual and I don't see one.

The ACC terminal was the only choice on the system that I repaired. Can you look at the control board IRL instead of the schematic? Or, can you see the make & model of the board & contact the manufacturer of either the board or the Aprilaire?

I don't see an ACC anywhere on the board.

Am I correct with my understanding that the Infinity Controller can adjust the humidifer and in turn the humidity? Or should I still wire in the Aprilaire humidistat?

So it seems the HUM and the COM are not the correct way to hook up direct to the solenoid valve?

Welcome to the forums.

Are you experienced in programming that thermostat ?
You'll need to set humidity comfort levels for occupied, unoccupied, vacation mode, etc.

You will not need the humidistat.
I'm looking at the wiring requirements for it now. I'll reply back shortly.

I marked the two terminals you will be using in blue boxes. You will connect these two terminals directly to the yellow wires coming from the humidifier's solenoid.

Thanks PJ.

I would say I am fairly versed in the Infinity Control. I've not come across issues that I couldn't overcome. Yet. I personally set up all comfort profiles and see that humidifier is one setting available as well.

This is a communicating system to my knowledge right?

Thanks PJ. I will work on this and see how it goes. Much easier than I thought in terms of wiring.

This is now installed and I did a full setup on the Infinty control. Made sure that the humidifier was shown as installed.

I don't hear any clicking at the solenoid nor any water out the drain tube. Does it take some time for it to all kick in or is it something else?

Thanks.

The solenoid should click in immediately and you should hear water run instantly.

Do you have a voltmeter ? Check for 24vac at the C and HUM terminals. If it's not there then you may have a programming issue.

I found out the saddle valve pin was broken. I am getting 24 volts per a volt meter at the humidifier and hear it click now. I readjusted the wire on HUM.

Thanks so much!!

Add the "replace the saddle valve with real valve" to the future to do list.
