The humidistat can can turned down in summer to ensure that the unit
doesn't come on during the cooling season.

I believe our furnace has only one speed.

The Y/T terminals are energized when the blower is running. You've
suggested a different type of relay, to avoid installing the clunky "sail
switch", but I'm still determined to power the unit from the low-voltage
strip on the furnace.



I guess if you already know everything, you don't need to ask for help.
