I would hope that an hvac tech would know to put the stat in before the

humidistat.

Not the fellow that installed mine! He put it on the supply, despite my
arguing that made no sense. And I went through two or three AutoTrac
humidistats. None ever worked. I don't know whether being on the supply
destroyed them, or they are simply prone to failure. So he ended up simply
wiring the two humidifiers to go on whenever the furnace is on.

So far this has not been a problem. The house has a huge volume, ancient
leaky windows, and an oversized furnace (200,000 BTUs) that doesn't run too
much. But I am replacing the windows soon. It may become a problem. Or
maybe not.
