To define my "freeze condition," meaning being away for a week during
possible 0 deg weather, and the heater is shut down because of a $50
condensate pump failure. Since it is on a concrete basement floor, I'd
rather that the furnace keep going, but again, I dont know how much
condensate it generates. The Aprilaire, I know uses lots of water.

What is the opinion out there? Is it better to shut the furnace down to
avoid acidic condensate from a high efficiency gas furnace, or put up with
repairing burst pipes?
By breaking the R line, I can shut down the furnace, humidifier, and AC
unit, but not just the humidifier and AC unit.

Not sure about the freeze condition, but we all didnt tell him that you
dont
need 2 relays, but the freeze thing gets me...but...if he would simply
wire
that R line up, he would be hokey fine..

I have a newer Rheem RGRA gas furnace with a Rheem A/C controlled by a

to use the condensate pump's cutoff switch to shut down the A/C and the
humdifier water supply, but not the furnace, to avoid a freeze
condition.
How can I wire the system to work? The alt.hvac guys were less than
helpful.
Thanks.

Maybe they weren't helpful because they didn't understand what you
want to do. I don't understand.
