HI guys, I have a Bryant Heat Pump system with axilaury heat and A/c, I want to replace the Honey programmable thermostat, but still reluctant to install it myself since the wire label different.
My new Honeywell model is TH6110D1005 and it has following wire label.
G
O/B (W)
C
Y
R
Rc

Both R & Rc come with a jumper, and it indicated only to be removed for two transformer systems

My old Bryant thermostat has following label
W
O
G
R
C
Y

Any expert out there please help me. Thanks a bunch

Are you sure your new stat has no more terminals? It should have a e and a aux and probably a L if it does not the stat you have is for heat pump only. Not heat pump with auxilery heat. You will need to take it back and get a 2 heat 2 cool stat

Yes, I'm sure. I think I just got the conventional heat with heat pump. But why it has to be 2 heat 2 cool, instead of 2 heat and one cool. Please explain.

Thanks greatly for your help.

It can be 2 heat 1 cool, but it must be one that will do heatpump with aux heat. Coventional with heat pump has no connections for the aux heat

Thank you Josh, Once I exchange my thermostat, I'll ask for your expertise again.

Thanks

The thermostat you bought will work. The aux heat will come on when the system goes into defrost mode. The only down fall is that it will not bring on the aux heat if you have a 2 degree swing on the temp of your thermostat.

T-top

How will it bring the aux heat on when it is not wired up? If it gets cold outside it will never keep the house up to temp. not only that but he will not even have emergency heat.

The heat pump is what turns the heat strips on in defrost mode all hvac techs know that don't they.

All techs also no that this stat will not work. Inless you live in florda and do not need back up heat.

Josh make sense, and you also make sense, since my Bryant thermostat doesn't have the axilaury connection heat either. Base on my Bryant wire code with the new Honeywell TH6110D series, what is your recommendation of connection. Please explain. I've look at the Honey well TH6220 which is 2 heat 2 cool, but the wire connection is more complicated. Please let me know what is your recommendation.

Thanks a bunch

And also, on my old system, whenever it goes below at least 3 degree inside the home versus the setting, the EMT heat will kick in, but within 2 degree, it won't kick in

How many wires do you have at the t-stat?

And what city are you in?

I am not sure how your emergency heat is kicking in if you have no E at the stat? But yes you can wire it up the same way as the old stat and use it that way, bu you will not get emergecey heat. What does then new stat say? 1 heat 1 cool?

And what city are you in?

I have 8 wire, but only 6 wires are being use by my Bryant thermostat as shown on the list. Would you please takes a comparison between the Bryant and Honeywell labels and let me know what wire go with what.

I'm living in Lafayette, In which is about 2 hours South of Chicago. The weather is very cold up here. I was dumb enough to get the heat pump instead of gas heater for my home.

Sure,

R- red jumper to rc
g-green
y-yellow
o/b-orange
c-probally blue
But you have no place to hook the white with this stat

I don't understand either. This is out of my league. But my Bryant theromstat show, cool, heat, EMT, and fan if I push the mode button.

All the wire connection are used as shown on the list.

I'm scratching my head now and trying to figure out what to do.

Are there any other terminals on the old t-stat that are not being used?

Maybe this is why you do not get good heat. It may not be wired right.

So you saying that I still need to connect the R with red wire and still leave the jumper in between R & Rc??

But the White one is giving me a dilema.

Yes red to either r or rc and a jumper between them. When your emer heat lite comes on 2 degrees lower then the setting does the air get warmer? Have you noticed?

With the HOneywell TH6220D which is 2 heat 2 cool
It has the following connection:
Rc, R, W (O/B), W2 (AUX), Y, Y2 (E), G, L, C

Please explain how to do electrical connection based on my Bryant connection.

Yes, the emt heat is a lot warmer and quicker. The green light on the thermostat
Turns on too

OK with the 2h 2 c

Red- rc jumped to r
Yellow-y
Green-g
Orange-o
White- aux jumper to E
c- like I said probably blue but not sure what is on there now.

Yes, I just check, it is blue for C on my current thermostat. So, I need another jumper to W2 and Y2 right??

Jump r to rc, and jump aux to E

That shold do what your other stat was, but you will need to make sure you do the installer setup correctly to get the heat to work right.

OK,
Let me make this clear, Red to R or Rc with a jumper
Yellow to Y
Green to G
Orange to O/B which is also (W)
White to aux which is also W2 with a jumper to E which is also Y2
Blue to C
And L should be leaved alone right?

Correct L is just for a light to flash if you have a problem outside it is not needed.

Thank you so much Josh, you sound like an expert and I would trust your judgement on this. I'll buy the 2 heat 2 cool then hook up exactly what you said.

Thanks again. You're the best, and I'll let you know once I got it set up.

Great hope it work, just make sure to read the installer setup like I said. You will be fine!! And make sure to turn the power off before you start.

Josh, I have one final question for you. My current Bryant thermostat only show - Heat, EMH, Cool, Fan, Off. It does not indicate the auxiliary heat anywhere and I assume that Emergency and auxilery are the same thing.

My Honeywell TH6220D only come with one jumper and it is being used for the R & Rc. Do I have to make up another jumper for the aux and emh, or I just need to make one connection to emh and ignore the aux. Please let me know what you think. Thanks a bunch

I would put the jumper in. it will work just like your old stat did if you wire it to aux. the problem is if you do not put in the jumper. If you switch your stat to emergency for any reason with a wire not on the E terminal you will not get any heat.

Hey Josh, I have it installed and it worked like a charm. Thank you very much for your help. You're a genius man, and we need more people like you on the net to make other people life a lot easier.

Thanks again.

Hey, no problem, glad you got it working. Lots of time them t-stats can be confusing.

Hey Josh, I just ran into another problem, the heat work fine for a while, but when I switch over to A/C for the summer, I don't get any cool air but only hot air. Did I do something wrong?? Please let me know. Thanks

Do you have the orange wire on o? And did you set the cooling to energize the reversing valve. In the installer setup?

Do you have the orange wire on o? And did you set the cooling to energize the reversing valve. In the installer setup?

Yes, I have the orange wire on O/B . And the second question I don't understand. What do you mean my energize the reverse valve??

And I just switch it back to my old Bryant thermostat and it works fine. Something is wrong with the wiring. I can't figure out!!

Was there a section in you instulation manual that said installer setup?

was there a section in you instulation manual that said installer setup?

Yes, I did set up step by step, and then I just reinstall it back with step by step set up, I still have hot air coming out. Removed it again and replaced with Bryant and it works like usual.
