Hello, This is the first time I have posted a question on any webpage so I
will try to include all the info I have. I installed a UGPL 2-stage 100,000
Furnace , the coil is a RCSA-048 and the Condenser is a UAND-048. Against my
better judgement we installed this in a house that had foam insulation blow
on the roof and all exterior walls. I also installed a Honeywell Vison Pro
8000 with a Humidistat Dial installed on the wall next to the T-stat. The
fan motor doesn't kick into high speed, like the ODD is overiding the
thermostat and staying at a low CFM. That is the problem that is causing
this unit to freeze. The way I have it wired is like this; T-stat: Green to
G, Red to R and jumpered to one side of Humidisat, Black to W2, White to W1,
Blue to Y2 and jumpered to other side of Humidistat, Yellow to Y and Brown
to Common. On the Furnace it is: Green to G, Brown to C and jumpered to one
side of 24 VAC outside, White to W1, Black to W2, Red to R, Yellow to Y and
jumpered to other side of 24 VAC outside and Blue to ODD. I can take all the
wires off and jumper Red, Green and Yellow together with the Blue from ODD
and the fan still stays in a low speed, wired like that the fan should go
into high speed no matter what, according to the guy who makes the crap. So
I replaced the fan motor and ECM module like he says and no luck. What gets
me is that when I started the unit up 2 months ago wired like mentioned
earlier it worked with no problems. So that tells me that it is wired right,
but I still think that it could be the problem. Did I mention that I
replaced both control boards and the thermostat, not my idea but I was fresh
out. I have installed maybe 20 of these systems just not with a Humidistat,
so anybody installed one of these before that can point me in the right
Apparently you have not been to the training that centers on the GPL
furnaces and ECM motors. It was worth the time and money spent to attend.
Check with your supplier or your favorite Rheem/RUUD rep for the next
BTW... throwing parts at it is *NOT* the answer.
Hey why don't you offer some help instead of a reply like that. No, I have
not been to the training on the furnace. And my supplier is the one who
threw the parts at me at 8:00 last night. I know throwing parts in it is
not the way to fix it I have been in this business for over 35 years but
sometimes you just want to jump off the fucking second floor roof, and you
will take it any way you can get it. You ever felt like that? Let me guess
you don't do anything against your better judgement. Are you an owner or
tech, because it sounds like your just a tech to me another owner would know
what it feels like when the buck stops right on top of his ass.
Shhhh....he prob got the Vision Pro at Lowes, and the model they sold didnt
have the humidity control on it.
Even if it did, he probably has no idea how to access the controls to fire
it up and make it operational on the stat.
And you sound like a fuckin idiot. Pissin parts at an expensive system
is just plain god damn stupid. I dont give a damn if its 8 at night or
midnight on a Sunday. Learn your shit or call someone who does. You
tossing parts at a system just drives the price of parts up higher and
higher because the manufacturer is going to make money no matter what.
It all gets passed on.
By the way............you've got a shit for brains supplier with no
tech support too. Ive got one I can call almost anytime I like. Its
called building a relationship with a company.
Learn it and dont let the door hit you in the ass on the way out you
bitchy ol god damn fart.
Could it be, could it just be, that we, as pros that HAVE taken the course
CAUSE WE MIGHT RUN INTO AN ISSUE at some point, resent the fuck outa some
wannabe that cant figure out why his crap that he didnt get TRAINED on isnt
If you are not trained, you had no business installing it.
Obviously, you are not.
Sucks to be you, since I know you are gonna reply with another one of these
flames like you did to the ONE person that COULD have helped you.
You got what you asked for..free advice. You got it...now go figure out if
you are posting on a Website, or Usenet..cause Ill even help you out
there..it aint a fucking website sparky.
BTW..Im an owner, and as an owner of a company, Id damn sure have the
training to install equipment we would have to go service when it comes back
to bite you on the ass for short changing your customer.
Also...here is a big ass hint that should tell you that I think you are
FOS...I can call factory on an issue, and if they cant figure it out over
the phone, I get a nice factory guy that has fogotten more about the stuff
than I know to show up and make it work.
Gee....now, with your attitude, its no fucking wonder that no one will come
see what your issue is.
Now...sparky..have you tried to wire the damn thing without the HS in there?
Guess what? Logic dictates that if it runs without it, you fucked up or you
have an issue with the humidistat.
