Question about Aprilaire 700 Humidifier
If furnace has the 24v terminals, do I still need the transformer. Also which is better to mount on cold air side or supply?
If the funace has the 24 V you should use that but test it first with a call for heat to make sure it is 24 and not 120 coming out of that terminal!!!!!
Mount on cold air side with the bipass going to the supply.
