Just purchased the Honeywell HE260A whole house humidifier. I did not feel like buying the "installation kit" for 3/4 the price of the actuall unit.
That means that I want to hook up the humidifier directly to the furnace logic board. I did my research on the logic board (honeywell ST9160B 1050) went to Honeywell's website and found what pins the board uses to talk to the humidifier, "HUM" and "NEUTRAL" bar (duh, me).
Now the HE260A humidifier and humidistat are all operated on a 24vac loop (The installation kit comes with a sail switch (which acts as the on/off part of the loop). My big question is, is the logic board meant to handle that 24vac loop? I do not want to fry my logic board by sending 24vac into those connections, it is not cheap to replace.
***I tend to overthink things and my overthinking is that the logic board is meant to talk to a "smarter" humidifier, a humidifier that is powered as well as have a NO/NC connection that would connect to the logic board.
Otherwise my wiring would be as follows:
24VAC --- humidistat --- HUMIDIFIER --- LOGIC BOARD
--- = 18AWG 2 WIRE
Thanks for your help!
