Condensate pump wiring
I have a newer Rheem RGRA gas furnace with a Rheem A/C controlled by a
Honeywell T8600D thermostat, and an Aprilaire 760A humidifier. I would like 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. -- Rick |

Yo, CBHvac, you're out of your hostile environment here. Slink back to your
alt. hvac ******** where you and your buddies all seem to enjoy flaming the "homemoaner's" and your colleague's "professionally trained" butts with insults instead of offering your valuable opinion.

Condensate pump wiring
I was thinking of the more complicated relay route, but how about breaking
the tied common side of the humidifier and the outside A/C unit with the cutoff switch? Would that work? The only helpful comment from the "professionals" at alt.hvac, one said that the furnace condensate is acidic and per some codes, the pump should always shut the furnace down. Since I am away usually only a few days, maybe the risk of frozen pipes is minimal. -- Rick "john williamson" wrote in message ...

Condensate pump wiring
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. -- Rick "CBHvac" wrote in message ...

And if the pump fails, you WANT the furnace to shut down, unless you dont mind the few possible gallons of water that the furnace could produce in a week..

Condensate pump wiring
Dont you have a floor drain or sump pump in your basenent, so when
something springs a leak , and IT will , you will end up with a swimming pool , ruining everything. That must be addressed first. You are worried about a measly 50 gallons on the floor , when shuting down the furnace , bursting a pipe, could dump 50000 gallons in a week and cost you tens of thousands.. Gee Ask your ins co, Ill bet they dump you for your stupid ideas. Put in a house Sump . Put in 2 condensate pumps, Leaving when its zero out you need your furnace to run, not plan a shutoff, I would not wire a shutoff. |

"Since I am away usually only a few days, maybe the risk of frozen pipes is minimal." Over a few days I imagine the amount of water generated would not be excessive so why on earth would you ever want to take such a risk? I decided not to have my pump shut off in the event of a condensate system failure. I'll be away for as long as a month in the middle of winter and would, obviously, rather have water on the floor vs having to face frozen/busted pipes when I get home. I am currently going through the aftermath of a water damage problem that has so far resulted in approx $35,000 in rebuilding.remodeling costs. Happened while I was away, came home to running water from an over-flowing toilet and it's no fun. MLD "Rick" wrote in message ...

Condensate pump wiring
Well, from what I read of this snarl, it sounds like you don't want the
humidifier draining water into the condensate pump if the funace is dead, and the house is cold. On the humidifiers I've wired, the water valve is controlled in part by the blower fan of the furnace. So, if the furnace isn't running, the humidifier won't get any water. In short, it's a non issue. If the furnace isn't warm, it won't be blowing. If it's not blowing, the water won't be flowing. You can switch the AC, if you want. That's easy enough. But I wouldn't bother to leave the central AC turned on if I wasn't home. Another non issue. Have I been a bit reassuring?

The A/C contactor and humidifier solenoid share the same 24vac transformer.
They are both ac relay coil loads, zero-crossing would snuff any serious transients. -- Rick snip...........

This I do not know but If that is true, you could do it that way. I would not prefer to do it this way but granted you could and be acceptable. ++++++++++++++++++++++ John wrote: I would not even consider this due to the transits and current draw of the solenoid. It could damage the thermostat or the cooling anticipator circuit. It might work one time or a hundred times, depending on the thermostat circuit. I would put this approach in the "jerry rig" category. It would be very confusing for the service people down the road also. Not bad though HvacTech2, not bad John Williamson |

Condensate pump wiring

... I've wondered in my quiet moments how CBH manages to stay in business? I mean, in the couple years I was on alt.hvac he was consistently rude. Does anyone else wonder? -- Christopher A. Young No, why??? He knows his ****!! Unlike most in the trade. The knowledgeable always have work fixing the equipment screwed by hacks!! That's why the competent HVAC techs are in HIGH DEMAND! -- kjpro _-~-__-~-__-~-__-~-__-~-__-~-__-~-__-~-__-~-__-~-__-~-_ ( kjpro @ starband . net ) remove spaces to e-mail Want it done yesterday?

Condensate pump wiring
Your logic is partially correct. I would leave the ac on a higher temp for a
weekend, shut it down on longer trips. I dont go down the basement daily, and my old system had flooded a bit before I discovered the problem. It wasnt a big deal. As for the furnace, If I cut off the furnace with the overflow switch, you are right, the humidifier wont run either, but I risk frozen pipes. If I cut off the humidifier solenoid, and the pump fails, the furnace will continue to run, generating condensate and cause a minor acidic flood. Right, we've beaten this thread to a pulp. -- Rick "Stormin Mormon" wrote in message ... Well, from what I read of this snarl, it sounds like you don't want the humidifier draining water into the condensate pump if the funace is dead, and the house is cold. On the humidifiers I've wired, the water valve is controlled in part by the blower fan of the furnace. So, if the furnace isn't running, the humidifier won't get any water. In short, it's a non issue. If the furnace isn't warm, it won't be blowing. If it's not blowing, the water won't be flowing. You can switch the AC, if you want. That's easy enough. But I wouldn't bother to leave the central AC turned on if I wasn't home. Another non issue. Have I been a bit reassuring? Hope so! -- Christopher A. Young Learn more about Jesus www.lds.org www.mormons.org . . "Rick" wrote in message ... I have a newer Rheem RGRA gas furnace with a Rheem A/C controlled by a Honeywell T8600D thermostat, and an Aprilaire 760A humidifier. I would like 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. -- Rick |

Young As I just replied to your previous post, this is exactly why we are in DEMAND!! Below is the OP, re-read the post and see if you can comprehend the question he actually asked. Competent techs : 1.) to be able to read and follow directions 2.) to be able to find the problem and be able to solve it -- kjpro _-~-__-~-__-~-__-~-__-~-__-~-__-~-__-~-__-~-__-~-__-~-_ ( kjpro @ starband . net ) remove spaces to e-mail Want it done yesterday?
