Default connecting a humidifier to Rheem furnace?



Nat


Followup: looking at this diagram

http://www.alpinehomeair.com/view.cf...1-3B9839F377F0


it seems that I could just pull some thermostat wires from the furnace
control board and piggyback off the "W" and "C" terminals (I'm assuming
W is White e.g. heat and C is common) to only energize the humidistat
when the thermostat is calling for heat...


You mean energize water valve solenoid thru humidistat? Just hope
thermostat lead(W) has enough juice to do this. I used the 24V AC step
down tranny which came with the humidifier. I don't use ODP.

yes? No problem with that
plan? (I could get rid of the sail switch and separate transformer if I
did it that way, too...)

Yeah, I don't really know what I'm doing, but I do know enough to see
that the way this installation that I'm messing with was done is kind of
Rube Goldbergian and also does not lock out the humidifier when the A/C
is on which is the main reason why I'm trying to redo it.
