Heat Pump System - Single Stage or 2 Stages?

Post by Bob Simon
I'm looking at programmable thermostats for my heat pump -- Goodman
GSH14030 compressor and ARUF3030 air handler with a 10kW heat kit.
I want to determine how many stages of heating and cooling I have so I
went to the Goodman web site and searched the spec sheets for the word
"stage" but it was not listed this way.
Can someone please tell me if this is a single stage system or
multi-stage? For two stage systems do both the compressor and air
handler need to be two stage or is this determined by only one of
these components?

If the system isnt working correctly, there is a 99.999% chance that its
*NOT* a problem with the thermostat. Your local *COMPETENT*, licensed,
insured, professionally trained, HVAC technician will know what your system
needs, and should have one on the truck. FWIW, I understand that the big box
stores will no longer take thermostats back, unless you exchange it for the
exact same one you bought in the first place....even if its the wrong one.

The system is working fine. What did I say that makes you think
otherwise?

*most* of the time when folks comfort systems are not working properly, they
automaticaly think its the thermostat that is the problem, without realizing
thats like saying my car is broke, if I get a new key for it, it will run
again. Or that it needs some more of that "freezone" stuff. Never mind that
the system is over 10 years old and has never been serviced since the day it
was installed. Yes its real obvious to a *competent* Technician when the
system was hacked in by the lowest bidder, that its never been serviced,
lots of candles have been burnt over the years, lots of fried food, smokers,
etc.

Bob;

Your system is a 14 SEER 2.5 Ton Heat Pump. You will need a single stage
cool, 2 stage heating thermostat. The second stage for heat is the strip
heaters. Look in the instructions that came with the indoor unit. It will
show you how to connect your new thermostat to your system. Good luck.

And if you find a problem call your local HVAC repair people. They'll help
you, but there will be a fee tied to the help. We have bills to pay too.

Thank you. Is the reason you know that the compressor is a single
stage because it only has one BTU rating?

The old thermostat has a single O/B contact whereas the one I'm
considering buying (White Rogers 1F95-1277) has both an O and a B.
Currently the orange wire goes to O/B - the changeover relay. If I
purchase the 1F95-1277, how should I wire O and B?

You and "noon-air" seem to make a lot of unjustified assumptions.
Perhaps you and he are usually right but I have to wonder. It looks
to me like you're trying to prove that do-it-yourselfers are stealing
your livelyhood and I happen to be a convenient target for your
unhappiness.

For your information, over the past two years I paid a qualified
installer about $7k to install two new heat pump systems in my house.
A week ago when the WR 1F82-261 thermostat he installed died, I
re-installed the old mercury switch thermostat. As I mentioned, the
system is working now. I enjoy doing small repairs that are within my
capabilities and am completely confident that I can install and
program a new electronic thermostat.

I am still hopeful that someone in this group will confirm my
expectation that I need to jumper the B and O terminals for a
thermostat where they are separate terminals.

Hi Bob,

Interesting, isn't it...?

Unfortunately, I know nothing that will allow me to assist
in answering your questions, but I will tell you of
experiences I had here about a month ago:

I posted some questions relating to an insulation job we
were considering, and, in return, got responses that fell
into two distinct categories:

Some folks were extremely generous with their time and
knowledge.

Others hurled insults, and, as far as I could make out,
became angry at me apparently through some twisted logic
relating to the kindness of the folks in that first group.

Eventually, the generosity won out because some of that
group, tiring of the nonsense, simply took the discussion
off line and wrote to me privately. I remain deeply
appreciative of that assistance.

Interestingly, based in part on the good counsel I have
described, we decided on a particular approach, hired a firm
to do the work, and are now about $12000 into the
modification we needed.

I do hope that you get your questions answered, and, were I
in your shoes, I'd check my email regularly.

All the best,

All my systems have a minimum 5 yr parts warranty...
So in that case, I'd call the contractor back and have them install a new
stat.
While they're there, have them clean and inspect the system!

Hook the orange wire to the O terminal and nothing to the B terminal.
The difference between the 2 is when they are energized. The O is
energized in cool which is the most units are wire (including yours)
and the B is energized in heat which is the way Rheem, Ruud, and
Weather King units are wired. Make sure you kill the power to the
indoor unit because if you touch the wrong 2 wires together by
accident you'll pop the low voltage fuse. As far as programming, just
read the manual not to hard on White Rodgers T-stats. Good Luck!!!

You don't even know me. For such an idiot my answer is correct.
Don't most heatpumps have strips as auxillary? Unless it's a dual
fuel or water furnace that's the way they all work except for maybe
ground source. Did you read that last statement before you posted
it. It makes no sense and I'm the idiot.

$7,000 for 2 systems is really cheap unless you provided the equipment. If
the installer provided the equipment and t-stats, the stats are still under
warranty. Call the installer back to make it good under warranty, unless he
is out of business because he didn't charge enough.

What did the directions to the thermostat say?? What do the books for the
air handler and heat pump say?? You need to know if the RV is energize in
heat or energize in cool. I know what it is, and will leave you to your
homework to figure it out.

I thought the same thing & didn't want to say anything but since you
mentioned it the Air Handler he's got isn't a true match with his
condenser. ARUF3030 only matches with the Goodman 13 SEER condenser.
The only way to get 14 SEER is with an ARUF1931 & field install a TXV which
together cost about an extra $175.00. That means the cost should have been
$7,175.00 <g>

multi-stage? For two stage systems do both the compressor and air
handler need to be two stage or is this determined by only one of
these components?

Bob;
Your system is a 14 SEER 2.5 Ton Heat Pump. You will need a single
stage cool, 2 stage heating thermostat. The second stage for heat
is the strip heaters. Look in the instructions that came with the
indoor unit. It will show you how to connect your new thermostat to
your system. Good luck.
And if you find a problem call your local HVAC repair people.
They'll help you, but there will be a fee tied to the help. We have
bills to pay too.

Thank you. Is the reason you know that the compressor is a single
stage because it only has one BTU rating?
The old thermostat has a single O/B contact whereas the one I'm
considering buying (White Rogers 1F95-1277) has both an O and a B.
Currently the orange wire goes to O/B - the changeover relay. If I
purchase the 1F95-1277, how should I wire O and B?

Geez;

One question at a time. - I know is single stage because it is. A 16 SEER
Goodman is 2 stage, the 14 SEER model is single. The O/B terminal for the
reversing valve on the thermostat you have can be / is programmed through a
menu. The 'cheaper' white rogers thermostat, is not. It is likely your
Goodman is default to Heat, so the reversing valve is active during the call
for cooling, hence 'O' terminal use.

Why don't you just hire a trained professional? If your not sure, it would
be better to hire one now, instead of having them repair failed controls
later.

Save yourself time and money and have a competent HVAC tech install a
YTH9421C1002.
As it's obvious that you don't know which one to use, which leads to you NOT
knowing how to hook it up properly. Then there's the programming issue.

I\'m looking at programmable thermostats for my heat pump -- Goodman
GSH14030 compressor and ARUF3030 air handler with a 10kW heat kit.
I want to determine how many stages of heating and cooling I have so I
went to the Goodman web site and searched the spec sheets for the word
"stage" but it was not listed this way.
Can someone please tell me if this is a single stage system or
multi-stage? For two stage systems do both the compressor and air
handler need to be two stage or is this determined by only one of
these components?

The compressor has four stages, and the fan has six.
