Humidifier Wiring Question

Hello,

I have a Carrier Infinity 96 Furnace and would like to connect a 24 V Air King Drum Humidifier to it. The furnace panel has a spade terminal on the circuit board labelled "HUM". I understand one of the wires should connect to it. Where should the other wire connect to ? The panel has a 24 V screw terminal block at the front labeled

W2 Y1 DHUM COM24V W/W1 Y/Y2 R

should the other wire connect to COM24V ? (There is already a wire running to it from the A/C compressor outside)
I would like to be able to control the humidifier with the furnace's existing programmable thermostat, preferably to have it turn only when the blower motor is running. Your help is much appreciated... Here is a link to a photo of the panel.

You got it put its com wire on it also. That wire on it is the com going to the condenser outside like you said.

 

Thank you ! Will this piggyback connection make the thermostat run only when the furnace fan is running and depending on the Infinity Control humidity setting ?

 

I don't know how the Infnity control works. but chances are it will turn on the humidifier on call of heat and/or fan on.

 

I wired it yesterday and it works exactly how I wanted it. Turns on only when furnace is supplying heat and according to the humidity setting on the Infinity control. Many thanks !

 

Thanks for the update, and glad to hear it's working the way you wanted!

Have a great weekend!
