I had a goodman gmv95 two stage furnace installed controlled by a honeywell visionpro iaq .the old furnace had a general 1042 power humidifier which i would like to control through the vision pro my installer was not very familar with the vision pro and hooked it up but cannot get it to work. can someone talk me through this set up as i am getting fed up waiting for him to return. I am a electonic tech by trade so It should be pretty straight forward i would think. from what i can tell he has the two wires from the humidifier going directly to the interface module of the vision pro . should it not first go to the furnace board to pick up the 12volts then to the control module.
