Hello, which two terminals were the 24 volt wires for the humidifier attached to,?

Normally they are attached to W and C, at the thermostat terminal strip in the furnace but that depends on how the controls are wired.

Customer reply replied 8 months ago
Yea, that's the problem. I took off the humidifier wires and didn't look to where they were attached. I have two controls, one for the furnace and one for the humidifier. The furnace will not heat up past 65-70 degrees. Do I need to reconnect the humidifier?
