Hi, I have a Amana RHA24B2D condensing unit and a Lennox CB18-26-2P blower with an AUX heating coil. I recently purchased a Honeywell 8320 thermostat. I'm not too sure I have it wired correctly. I formerly had a Honeywell 3611 programable HP tstat installed.

The terminals were as follows:
(Top row) B L C
(Bottom Row) R W2 E W1 Y O G.

"R" was connected to the Blue wire, (Equip monitor?)
"W2" was connected to yellow wire (Aux heat realy?)
"C" was connected to the white wire (1st Stage Heat relay?)
"E" was "free"
"W1" was bridged to "Y" (orange wire to "Y" termianl)
"O" was connect to the red wire (Changeover valve?)
"G" was connected to the green wire (Fan Relay)

What are the correct terminal connections for the Honeywell 8320? Note: On the 8320 the "RC" and "R" terminals came bridged already.

I would love to post pics..but can't.

 

joenupe,

where were the thermo wires placed on the old one?
did the new one not come with any directions?
was the old one broke?
unless i have completly lost my mind, the color wire and the terminals that you describe, i can't see for the life of me how the system would have worked in the first place, except to make the fan run(is this a test?).
by the way, we, do not keep a book (well most of us) of what type of parts that people try to replace at our computers. to help us to help you faster,
post a link on the parts that you had and what you are trying to replace it with.
also what wires are coming out of the wall at the thermo, and what wires are being used at the heatpump and airhandler? we are here to help,

I'm not quite sure if this is what youare looking for but the old thermo stat was a Hoenywell 3611 and the new one is a honeywell 8320 visionpro.

 

we got that on your first post, please tell us the rest of the info that i posted,,

Hi Barry, the thermo wires (8320) are currently set up as follows:

Y2 RC
L -red R (Bridged)
E O/B - red
AUX- Yellow Y - Orange
S1 G - green
S2 C - white

The unit comes on but the fan stays on all the time.

 

STOP NOW! Turn off the equipement before you ruin anything!

Go to the furnace or air handler and make notes of what wire to what letter on the board.

 

OK On the breaker board on the air handling unit it looks like this:

yellow O (terminal) White wire added by Tech in 2002
O (terminal) Green
Orange O (terminal) Yellow
Blue O (terminal) Blue

 

need model number,serial number as well as all the other stuff i asked earlier.
just tring to help.( 8320 can't find it)
barry

 

Did you follow fig 15 in the install manual?

And set up to #7?

 

On the board you should have

Y
G
W
R... ect..

 

i wanted to be that forceful, jay , but i was trying to get more info from the poster. never in my life have i seen a thermo wired this way. i also tried to google the #'s of the thermo nothing even at honeywell would come up,
without more input from poster i see your demand to cut power to the unit.
barry

 

Yes followed step up and set installer code 170 to 7.

 

It's a Honeywell Visionpro TH8320U programmable thermostat

 

I agree about the color the first time around..

I wanted to avoid him frying his board/t-stat up. And we can go from there to get the colors matching..

 

joe,

just go thru the posts that i and jay asked, slowly, and try to answer every one. we know that it is an emergency situation to you, but please consider,
we ant't there at the problem, the more info we have the better we are to help out. so take a few deep breaths, take a pad of paper, and give us the aformentioned info.
barry

 

You got it. please let me know exactly what info you are looking for. if possible, I can take pics and send them to you. I really appreciated your help.

 

If you are able to take a picture, go ahead and take a pix of the control panel in the air handler, and post it on a photo host site like yahoo.. photobucket..

This site does not allow us to post on here. :-(

 

joe,

for one last time( i'm not really trying to be nasty) answer the post that i placed earlier 07/39/pm it can help us out a lot. what i, and maybe jay, will think that this is a simple thermo problem but you need to be a little more exact as to where all the control wiring is going to (we don't want you to burn a transformer out, or a control board, or a new thermo. please help us to help you.

barry

 

Sorry I didnt get back to you, I'm on the east coast and it was late. Thanks again for your help.

 

My terminal strip located on top of my air handing unit is labled as follows:

3 (yellow/white)
G (green)
W1 (orange/yellow)
R (blue/blue)

There is also red/blk wires tied to each other.
Red/Orange wires tied to each other.
Green/Black/Yellow wires tied to each other.

The Honeywell 3611 was working fine. I decided to upgrade to the Honeywell 8320. I believe my Amana is a 2 heat/1 cool type.

 

3? There is no Y on it?

I think there should be more wires and Letters(Terminals) tied up on to the therminal.

Can you take a picture of it for us please?

 

I should be home at 5pm (EST) Thanks!

Ok, That 3 is throwing me for a loop!

I looked everywhere on line to see what 3 is, came up empty.

Is there a wire drawing on the unit somewhere? (behind blower door?? Are you able to read it and see where 3 goes to and ties to?

 

"outside common on heat" and "indoor blower coil" The white wire is the common and the yellow wire is the Aux heat.

 

joe,

i looked last night until i fell asleep at the computer to find some sort of answer.
(dang neck hurt all day, smudged glasses, etc.)
it seems to me the there has been a lot of " engineering " on the control wiring on your system. let's try this; take another pic of the air handler diagram ( little more light please, we are as old as dirt), a good clear shot of the heat pump wiring diagram, a photo of the wiring diagram for the new thermo and finally the control wires that lead to each one of the above mentioned system parts. i know that jay and as well as the rest of the guys i would like to solve this issue without you having to go pro, but it may become inevitable, since we are not there to trace down the control wiring. ps , i still got your #, not going to call unless i have a solution. still working on it, you are not left in the dark.

Thanks! (And remember, I live in north Jersey...nothing is EVER as it should be.)

joe,
was able to print the one diagram, please send the others as i asked for earlier

we be here to help ( i meant to say it like that, a little humor, very little).

barry

 

Ok, Sorry I wasn't here today. I just got home 6 min ago, and came up that 3 is common side.


Ok,

I see 3 sets of wire in the pic. 1 goes to t-stat, 2- goes to outdoor unit, and 3- goes to ???

We will have to "Clean House" here.. I am not sure how or why it wired that way. but below I am going to list what needs to go where.


This how it should be done.

Tstat:
RC-R should go to R on the air handler (Red wire)

O/B should go right out to the outdoor unit for the reversing valve. (orange wire)

Y should go out the the outdoor unit to the contacter (Yellow wire)

G to the air hander's G (Green wire)

C to air hander's 3 (Blue wire)

L to the heat pump to let you know if you having problems (Some unit don't have this, so you may not be using this.)

Aux should go to W1 on air handler (white wire)

Jumper E to Aux


Air handler:

R to RC/R on tstat

W1 to Aux/E on t-stat

G to G on t-stat

3 to C on t-stat and common side of heat pump.


Heat pump:

I don't know Amman heat pump but I am guessing here.

should be 4 maybe 5 wires.

1- low voltage from Y

2- to 3 (Common)

3- From O/B on t-stat

4- Defrost mode (Turns on Aux heat at W1)

5- Letting you know there is trouble (May not have this) goes to L at t-stat

 

OK Should I power it up now? I did the tstat connections as posted.

 

If you followed what I show, then yeah go ahead.

 

The wires on the air handler are set up different. Do you want me to change them as you previously posted? (Yep. this is starting to look more and more like a the contractor said "do whatever it takes to get it to work ".

 

joe,
we have spent more time on you than the delivery of my first child, just kidding, i kid, thought that there ought to be a little humor around here.
JAY has the the wiring set up as we were all taught as pups, thats what blows our collective minds as to how your stuff is wired. that is why i asked that you try to provide us the diagrams of the heat pump and the thermo. the pic. of the air handler that you already sent helps, now we need the other pieces to this puzzle. i'm like JAY, we may need to start up new. we have seen that control wires get messed up in the walls and some jackleg will sub a different wire to take care of the system and not write it down somwhere. what u think, JAY?

This how it should work.

If room temp is at set point there is call of heat, the heat pump should kick in.

If the heat pump can't keep up, it will turn on Aux heat.

If it's really cold out where the heat pump can't do anything. You turn on Emg heat and it will only run the electric heat strip.

 

Yes, the wires MUST be rewired like I said. Otherwise, it's not going to work. As it already did for you earlier.

if you MUST have heat for now,

Just hook up E to W1

R to R

and turn it on to Emg Heat


Undo the other wires.

 

the only thing i could say to what JAY said is, you said that the old thermo worked fine. kill the power to the system and hook it back up.

do you want me to change these wires?

 

Yes, it needs to be "cleaned up" But for now to get warmed up, Undo the wires, and just hook up W1 to EM at T-stat and R to R C to C
