Why Does My Nest Say “Delayed?”

With a cheap piece of technology, a Nest thermostat is a wonderful way to simplify your everyday routine.

However, having problems with your Nest thermostat, particularly during high temperatures, may be more than unpleasant; it might be fatal.

Here’s what to do if your Nest thermostat says it’s delayed.

Why Does My Nest Say “Delayed?”

When there is a power outage, a Nest thermostat will display delayed. The Nest Thermostat is powered by a C wire. 

It won’t have enough power to work correctly without one, so the Nest thermostat will act as though it has a low battery and display the delayed status on its menu.

Furthermore, if the wiring setup includes an EZ Wire but no C Wire, your Nest will not be able to draw enough power and will display an error message that says “Delayed.”

How to Fix the Delay Issue

The C Wire plays a critical role.

If you have a Nest Thermostat, please do the following steps to resolve the nest delay issue:

Step #1 

Take a check at the power connector on the back of your Nest device, at the bottom.

It’s usually written on a sticker or label that states “Wired to 120VAC 20A.”

Nest now requires the C wire in order to work.

If it doesn’t have a C wire, you’ll need to buy one to make this work.

Step #2

Now that you know what’s causing the issue, you’ll need a C wire or a power extender to receive enough power from the outlet it’s plugged into to make it work.

If your house was constructed with recent electrical wiring, it may already have one installed; if not, check in your circuit breaker box for a two-prong female receptacle with a screw or push button, and then search online for other places to purchase one.

The C wire is inexpensive, and the Nest Thermostat requires close proximity to the receptacle.

If you don’t already have one, make one with your hands.

The electricity it produces is sufficient to switch on the thermostat.

Step #3

Follow the C wire back to where it enters your house on your circuit breaker box now that you know it’s required.

A female connection should be attached to the C wire.

The kind of housing for your thermostat determines how to reconnect the C Wire to the wall.

It might be a 4′′x4′′ or a 2′′x4′′.

Taking the Nest unit off the wall and connecting the C wire straight into your wall without the Nest is the best approach to assure success.

If you have access to professional electrician, he can take care of this for you and ensure appropriate installation.

Step #4

  1. Replace your thermostat on the wall and test it once you’ve connected the C Wire. It should now function correctly.
  2. Please follow these procedures if you suspect you may need to upgrade the firmware:
  3. Change the date on your Nest thermostat to the day you think it was created by going to the Nest website and logging in using your email address and password. If you change the date incorrectly, you can have further issues with it functioning or not working. If this does not resolve your issue, we suggest contacting Nest directly for help, since it is not covered by their guarantee.
  4. To update the thermostat, make sure you have a “Authorized Nest.”
  5. Update your thermostat using the URL below, which you may find in the app or on the home page of your browser:
  6. https://mynest.googlecode.com/files/ThermostatFirmwareUpdate.mbh
  7. Unplug your thermostat when it finishes, wait a few minutes, and then plug it back in to check that the updates were successful.
  8. This should resolve your issue and eliminate any delayed status issues you’re having with your Nest Thermostat!

What to Do If You Don’t Have a C Wire

If you don’t have a C wire, you may attempt another method.

Using a Venstar adapter, which allows you to easily connect more wires, is one of the tried and true methods.

A thermostat that does not need a C wire may also be found.

Z-Wave is the most common thermostat in the business since it does not need a C wire.

Examine your present thermostat to see if you have a mechanical or electronic thermostat before proceeding.

A mechanical thermostat has more wires and is likely to be bulkier than an electronic thermostat.

Final Thoughts

You’ve also learnt how to solve a problem without a C wire.

Remember that this isn’t a panacea for all of your Nest issues.

Whether you still need help, we recommend contacting Nest to see if it is covered under warranty.

Frequently Asked Questions

What kind of thermostat am I using? Mechanical or electronic?

Look at the back of your present thermostat to see which sort of thermostat you have.

It’s a mechanical thermostat if the wires are longer and the casing is constructed of a thicker material.

It’s an electronic thermostat if it’s composed of plastic or metal and has smaller wires.

How to change the time on my Nest thermostat? 

Follow these simple steps to change the time on your Nest thermostat:

Log in using your email address and password on the Nest website.

Select the thermostat you wish to modify the time for in My Nest. Change Time is a menu item under Current Date and Time. Choose this option.

The option to adjust the date will appear on the following screen. Choose that option. Choose one of the choices on this screen.

The time for your Nest Thermostat will be shown on the following page, and you can then pick the time you wish to enter. You’ll be able to alter the time on your smartphone after that.

How can I tell if my Nest Thermostat is broken? 

You should contact someone from Nest to handle your issue because it could be one of many possible causes that are not covered under warranty.

I have a Wi-Fi thermostat that constantly has a delayed status. 

If this approach hasn’t remedied your issue, you should hire an electrician to inspect your wiring and make sure everything is connected properly.

How do C wires and Z wave thermostats differ?

C wire is a control connection that allows your thermostat and HVAC system to interact. A Z wave wireless thermostat does not need a C wire, which means that it was designed to function with any installation, regardless of whether or not you have one.

My Nest thermostat does not have a C wire. What should I do? 

There are a variety of alternatives for getting Wi-Fi thermostats to function in flats or houses without a C wire. One of these is to use a Venstar adaptor, which makes it simple to connect wires to your thermostat. Another option is to get a Z-wave wireless thermostat that does not need a C wire.
