I wanna wire in my humidifier to my ecobee . The transformer on my firnace will not be able to handle the additional load so I will be using the transformer provided with the humidifier in addition. How would i wire this up
You didn't say which humidifier you are using but if it has a transformer than it requires 24v to activate the solenoid. You will need two wires between the humidifier and the thermostat. You need to have the thermostat installed and programmed for two wire control (ACC+ and ACC-) before powering up the humidifier transformer.
If you only have one spare wire then you'll need to use a relay.
It's a bypass humidifier. Havent decided which one i am getting. .
I assume the humidifier solenoid has to be on the acc+ always or doesn't matter
Ok i ll check how many spare wires there is at thermostat . If only one. Can u post the wiring for me and what kind of relay would I need.
will i damage the thermostat if i don't program it first before powering the transformer?
You can set the thermostat up for humidifying with or without heat.
Normally you would use the furnace transformer and the ACC+ terminal to run the humidifier.
Since you want to use a separate transformer.... the two transformers can't meet.
Programming the ACC+/ACC- first keeps the furnace power from getting to the ACC+.
I ll see how many spare wires I have and then see if it's easily feasible to upgrade the existing transformer. Whats the wiring for just acc+ how does just 1 wire go up
So I ll be u using the manual humidistat to control this . I only need it when s there's a call for heat . I will be using the transformer thats provided with the humidifier can I wire directly to w and c or do I need a spst relay. If so why ??
Hi there
I'm in the middle of installing an Aprilaire 600 (automatic version), but the only part of it I'm having trouble understanding is the wiring instructions.
Based on the following wiring diagram, and the following labeled picture of my furnace's control board, can someone please tell me exactly how to wire this thing up?
My furnace has a "HUM" terminal on the board, so does that mean I can wire the G wire between the furnace HUM to the humidistat G and skip wiring my [Nest] thermostat G to the furnace G as it shows in the wiring diagram? If so, could low voltage wiring be used here, or a thicker gauge wire like some of the other terminals near the HUM terminal on the furnace?
Would also appreciate if someone can clue me in, where on each of the wires in the wiring diagram one should use low voltage wire versus thicker gauge wire.
Much appreciated!

[color=#3c3c3c]I have a single Aprilaire 700 humidifier on return that is used by two Goodman furnaces. I need to know how to wire the [/color]Aprilaire 60 humidistat [color=#3c3c3c]to both furnaces so that either one being on will turn on the humidifier.
The two brand new Goodman furnaces (replacements) were professionally installed but I opted to later replace the old humidifier that wasn't working and not hooked up as part of the install.
Now I could use some help as to the correct way to connect the inputs and outputs.[/color]
