I used to have an Aprilaire bypass unit at our previous house. I liked it
very much, but they are only available through contractors. Our last one
cost about $450 installed.

Note: Check the web, They are available from other sources, as the one
on my furnace proves.


Same here in NJ. I bought my Aprilaire at a shop that sells/installs
fireplaces, wood stoves, etc. I just walked in and bought one, took
it home in a box.




I just purchased a Honeywell HE260 from Home Depot for $199 (there is a
$30 rebate offer in effect until Nov.). It's quite similar to the
Aprilaire in styling etc. I've got it bolted to the furnace (Lennox G2 -
I believe) and the water supply connected.

Problem: The HE260 comes with a big honking 30VA transformer and a
kludgey "sail switch" (relay with a big "sail" that floats in the cold air
return and closes when air is flowing...Honeywell's way of sensing blower
activity). I want to avoid installing the transformer (24V) and sail
switch and, instead, just power the 24V solenoid water valve from the
furnace itself.

I doubt the solenoid draws more than about 500 mA. Is there any reason I
should NOT try to power it from the Y/T terminals (compressor contactor)
at the furnace's low-voltage terminal strip, which provides 24VAC when the
blower is on?
