Hello, I have a new iComfort thermostat, new SLP98 Furnace, and a Lennox outdoor temp sensor,(my Compressor is still an old Lennox). I would like to wire my Aprilaire 600 humidifier to the Furnace and have the iComfort control the humidifier. Question is on how to wire the humidifier to the thermostat / Furnace. Do I still need to wire in the Aprilarie humidistat, or can I just connect the 2 wires coming out of the humidifier itself directly to the HUM connections on the SLP98? I believe the SLP98 board puts out 24VAC to the humidifier so I don't even think I need a transformer. Thanks

One 24V H" terminal is provided on the furnace inte-
grated control terminal block. Any humidifier rated up
to 0.5 amp can be connected to this terminal with the
ground leg of the circuit being connected to either
ground or
the C" terminal. See figure 44 for location of
terminal.
look on pages 29-39 of the manual
