Help on wiring

[DilanPSmead]

should I use this do do my wiring or use my original wiring?

[DilanPSmead]

Current wiring, please tell me if I am wrong.

[DilanPSmead]

 

[DilanPSmead]

My old wiring

 please confirm I did it correctly.

[Houptee]

Is this a Heat Pump system?

Or a AC and gas heat system with 2 stage heat?

If it is a heat pump you use outer labels on old tstat.

So if you have a heat pump with aux electric heat then you wired it wrong.

Orange should go to OB it is what turns on the heat pump reversing valve outside (it should not be on  W1).

Hello folks,

Thanks for looking into this thread, @Houptee.

@DilanPSmead, I wanted to see if you'd seen Houptee's response. You might need to reconfigure your thermostat if you have a heat pump system with wiring changes. Please let us know if you have any other questions or concerns.

Regards,
Mark

[DilanPSmead]

As I said it’s using the google provided wiring diagram for now.

Hi DilanPSmead, 

I understand that the wiring setup can be confusing. Depending on your system, I can confirm what Houptee said: if you have a 2nd-stage heat system, you wired your Nest Thermostat correctly; if you have a heat pump system, move the orange wire to the O/B terminal and restart it for the wiring changes prompt. To verify, could you tell us the make and model of your system?

I'll look forward to your response.

Thanks,

Mark

Furnace - RHKL-HM2417JA

Heat pump -  RPQL-024JEZ

you all confirm to me the wiring setup because I’m using what the prompt said for now. The brown wire is connected as per the image on my original post. 

[Markjosephp]

Hey there,

Thanks for confirming that about your system. From your Nest Thermostat's wiring, move the orange wire to the O/B terminal and reconfigure its wiring by restarting it. Then, check its equipment settings to see if it's already configured as a heat pump system, and let us know how it goes.

Regards,

Mark

[DilanPSmead]

Please help me by telling me what color goes where. I just got my heating bill and it was way high!

[DilanPSmead]

Please see my prior images. Currently I matched my wires to the google provided wire diagram, yet idk which is correct.

[Houptee]

Red to RC

Blue to C

Orange to O/B

White to W1

Yellow to Y1

Green to G

Then make sure it is set up as Heat Pump forced air heat

with Aux heat on W1

Then you have to set up Heat Pump Balance setting to adjust how it uses the Aux electric heat coils.

This didnt seem to help our house is sitting at 69 When I told it to be at 60 heat and 64 cold. Please advise. Something still isn’t right. I had an pro install it and I’m afraid it’s wrong still.

[Markjosephp]

Hello there,

It's me again. I wanted to check and see if you had reconfigured your system as a heat pump with wiring changes. How's it going? Have you also tried changing the heat pump balance settings? Please let us know how it goes.

Mark

Hello DilanPSmead,

I wanted to follow up and see if you are still in need of any help. Please let me know if you are still having any trouble from here, as I would be happy to take a closer look and assist you further.

Thanks,

Mark

Mark,

after two phone calls to customer service, I have the attached wiring diagram. Note my white is plugged into the w2/aux.

[Markjosephp]

Hey there,

Perfect! Thanks for updating us with your thermostat's wiring update, and I appreciate your effort in reaching out to our phone support team. It appears that your thermostat is now configured as a heat pump. How's it going so far? If there’s anything else I can help you with, please let me know.

Regards,

Mark

[DilanPSmead]

Why do I feel like the nest learning isn’t saving me energy. I feel my energy usage since is installing it has gone up, not down.

my bill from Jan 20 Said 13,312 and now it’s Feb 2 and my usage is 14,150. I have tried to tweak my thermostat settings but still I feel that it’s burning more energy then my last thermostat.

[DilanPSmead]

I have a daily schedule set as so

6:30am 62-65

8:30am 65-68

9:30pm 60-64

should I turn on early on? Or what else can I do to help.

the heat pump will only turn on alt heat below 34 degrees Fahrenheit.

I also have the eco mode set at

59 heat and cooling off.

please help.

[Markjosephp]

Hello DilanPSmead,

I can see why you'd want to use less energy. It appears that your system makes use of the backup heat. Regardless of the setting you select, heat pump balance controls how frequently expensive Aux heat is used. Because Auxiliary heat is so expensive, running the heat pump for extended periods of time can be more cost-effective.

Please have a look at this article and let me know if you have more questions.

Regards,

Mark

[DilanPSmead]

As I mentioned I don’t have the heat pump balance option with my setup. That configuration was not working. I am honestly so angry this device is so complex for how simplistic it’s meant to be. See prior images of my equipment setup.

[DilanPSmead]

 

[DilanPSmead]

I honestly feel like my prior 7 day programmable Honeywell did better than this.

[DilanPSmead]

Mark,

do you have any suggestions??? 

[DilanPSmead]

I’m super confused. I have a 1 stage heat pump. 1 stage heat, 1 stage cool. Then I have a furnace.

should my w2 be white or brown like this?

 right now my white is in w2 not my brown.

[Houptee]

The brown was never used on the old tstat so it will not be used on the Nest only use the same colors that were connected (except for the S wires).

You said you have a natural gas furnace as the Aux heat correct?

Then you have to put White in W1 and the setup has to be for a Heat pump "dual fuel system" since you have a gas furnace (not electric aux heat coils correct?).

If what I am saying is correct about gas furnace then you do not set up heat pump balance you have to set a lockout "outside temperature" that the heat pump will no longer run, and it switches over to the gas furnace for the heating. So if you set it for 40 deg then if it is below 40 outside then gas furnace takes over.

• If you have a dual fuel system, a type of system with a heat pump outside and a separate heater installed inside your home, you won't be able to use Heat Pump Balance. If you have a dual fuel system, you can set a lockout temperature manually in the Nest thermostat's Equipment menu.

[DilanPSmead]

You said you have a natural gas furnace as the Aux heat correct?

yes I have an electric furnace.

I have configured the below 

Yellow -y

green -g

orange - o/b

Red - Rc

white - w2/aux

blue - c

are you confirming I’m setup correctly?  
also I have set the aux to run at 34 degrees and under.

[Houptee]

Do you have a Natural gas furnace? Do you get a gas bill?

Or no gas at all?

Is the Aux heat Electric heat coils in the air handler that turn on to assist the heat pump during very cold outside temperatures?

[DilanPSmead]

I have this heat pump

Rheem -  RPQL-024JEZ

and this air handler (furnace)

Rheem - RHKL-HM2417JA (electric)

so what should my wiring be?

[Houptee]

OK the wiring is correct.

You do not have a "dual fuel" system you have a "heat pump with aux electric heat".

So you need to reset and start the setup again and just tell the Nest it is a heat pump forced air with Aux heat "electric" on W2.

This is your problem, you have in the screenshot it shows 2 heat sources 1 electric and 1 gas but you do not have any gas heat source, so there should only be one heat source shown after you set it up correctly.

Once that is fixed then it will allow you to choose Heat pump balance settings to define how it uses the electric aux heat coils.

You do not want to pick a fixed temp for this kind of system you pick the heat pump balance it gives 3 choices for the balance settings.

Try that, hit reset and define the system as Heat Pump with Aux heat on W2 (NOT GAS Heat, NOT dual Fuel)

[DilanPSmead]

Step by step what do I need to do after reset? I’m doing factory reset now. But you say do single heat source.

[DilanPSmead]

Is my setup right or wrong?

[Houptee]

Leave the wiring alone it is correct.

The system should say under Equipment

Heat Pump (Not Dual Fuel)

Alt heat type Electric (Not Gas)

Alt heat source Forced air

Then you can choose the Heat pump balance settings

Hello there,

I wanted to ensure that everything was covered here.

Thanks for the continued support here, @Houptee.

@DilanPSmead, I hope you've seen Houptee's instructions and are able to set up your thermostat. If you're still in need of any assistance, feel free to let us know.

Regards,

Mark

[DilanPSmead]

Let me know if you are saying that my w2/aux - white should be in W1. I appreciate it.
