Nest thermostat continually heats

JoeR1939 — Fri, 21 Apr 2023 17:23:29 GMT

My Nest battery was low and thermostat was offline. I hooked up a recommended 24v supply and now it heats constantly. My old honeywell wiring is blue & blue/white twisted together to W1 and orange & orange white twisted together to Wh. 24v hookup went to C and Wc as per instructions. Any help is appreciated.

Hello JoeR1939,

Thank you for taking the time to let us know about your inquiry. I'd love to know more about this.

Could you share with us photos of your old and current thermostat's wiring? Could you provide a rundown of all the steps you've tried? Also, please check your actual thermostat's power readings in the Technical Info settings for the Nest Learning Thermostat and the Nest Thermostat E or the Equipment settings for the Nest Thermostat 2020 model.

I'll look forward to your response.

Regards,
Mark

Nest thermostat is on USB cable, display is normal, no errors, but continuous heating. It has occurred three times in the last couple of months. Display shows temp set to 18, current temp 22, but the boiler and radiators are active. Quick fix is to just power off but that doesn't help diagnosis

Hi there,

Oh! Thanks for the details. Does your thermostat have a C wire? Can you help me check its power readings from the Technical Info? This will help us determine if this is a power-related issue.

Regards,

Mark

If I understand the question, power is from a Micro USB cable not USB-C. I don't know anything about power readings, what does that involve?

Thanks

Hi there,

I'm sorry for the confusion. To be clear, what type of Nest Thermostat do you have? Also, from what country are you posting?

Regards,

Mark

Hi there @JoeR1939,

Let's perform a quick click test. If you have the thermostat on the Nest app, I'd like you to go with the app near the Heat Link and call once for heat and let me know if you hear any clicks. Wait for one or two minutes and then stop calling for heat and let me know if you hear another click.

Re: Nest thermostat continually heats

JohnS13 — Sat, 06 May 2023 09:38:13 GMT

Yes, clicks heard as you describe.

Yes, happy to receive any suggestions about troubleshooting, especially if/when the Nest thermostat plays up again. Thanks

Hi there! Could you please let me know if you received the email sent by my colleague?

I sent an image response on 6 May via email (not this platform cos it doesn't include an image option). Let me know if this hasn't happened or if I need to respond differently. Thanks for following up

Re: Nest thermostat continually heats

OannaCG — Tue, 09 May 2023 14:36:17 GMT

I sent you an email, please reply to it with the picture, because I couldn't find the email you sent previously and let me know here once it's done.

Thanks.

Hi Oanna, I only see postings here on this topic, I have not received other types of email - just the community mailer advising me of a new posting

I located the email you sent to us on the 6th of May, that was in reply to my colleague requesting the picture. I replied to it with some further instructions. Check your Gmail account and let me know if you received it once you've gone through it.
