The auto control works, you lower humidity just the point where there is
no condensation anywhere. It will maintain humidity so condensation does
not occur. Condensation leads to mold then rot of wood window frames.
Keep outside thermometer higher than any snow will ever get, my instaler
first put it at 6" I had him raise it way up to 5 feet in shade, N side.
Keep snow from resting on sensor, mine is under my elec meter. I close
airflow in summer with a damper and its mounted on the supply going back
to the return. The unit you have is superior to non thermostat controled
units by far. In fall clean the pad in CLR or similar acid solution.

Dont mount the humidifier on the supply side. Your heating unit has
many expensive electronic parts, none of which deal very well with
leaking water.
Dont clean the pad with CLR or anything else. They are less than $10.
Sometimes you can use them more than one year but the manufacturer
recommends that you toss it after 1 yr.

Why not use CLR, lime away etc , it cleans them it is metal, and that is
all you need. Its worked for years and is clear of any buildup. Leaks,
mine if it did leak is far enough away from the furnace where water
would not leak into it.

Because they are not designed to be cleaned. Its not a serviceable
part. It is meant to degrade. Thats why it starts turning into a
crumbling mess. You'll notice the honeycomb shape of the pad. It is
designed with and angled pattern to keep the water in the pad. Just
for ****s and giggle, install your pad upside down and turn the water
on. Point being, they are easily prone to leaking, falling apart and
making quite a mess. As an owner, technician, etc. I dont like
callbacks and cleaning a pad would deifintely cause me many callbacks.
Homeowners may choose to do this. Service companies wont.

Also, to the OP. Still dont believe it doesnt matter whether the
humidifier is installed on the supply or retun duct? You are correct.
It doesnt. Read the installation manual. It will tell you the same.
Aprilaire nor any of the other humidifier manufacturers care if it
leaks down into your furnace and causes damage.
Wait till it leaks down into your Lennox or Carrier Variable speed
unit. Especially under the furnace warranty. I hope you have lots and
lots of money because that water shorted board will NOT be covered.
Now are you catching on?

Excellent advice. Seems obvious, now that you mention it. Just the sort of
thing you learn from experience!

Thank you
