why does nest say delayed

Worried – Why does Nest say delayed? It is one of the common questions asked by people who are using Nest Thermostat.

It’s a common problem, in fact, almost a thousand people try to look for the solution to this problem every month.

So, in this guide, we will be giving you complete details on why it gives you this notification, as well as the procedure of how you can fix it.

To fix and get rid of Nest “delayed” message, you can use a C-wire (common wire) and link it to your device! With this, you wouldn’t get the delayed message any longer.

In anticipation of the ultimate solution to this nuisance, let us briefly discuss the reason why your Nest thermostat is giving you this notification.

Reason Why Nest Thermostat Say Delayed!

In the simplest and easiest way to put it, the “delayed” message that’s displayed by your Nest Thermostat is caused by the thermostat being underpowered.

What this means is that your device is not getting sufficient levels of power for it to function. This is also the reason why this message can also be caused by a power shortage in the thermostat.

Unlike other types of thermostats, which are wired and battery-powered, the Nest Thermostat recharges itself from the HVAC system you have at home.

Therefore, it’s not actually using its full power to control the thermostat. Now that we know the very reason why it’s displaying this message, how do you fix it?

Now, we’ll be answering your question: “Why does my Nest Thermostat say delayed?” and how to fix this issue!

We know that all of you might not be well-knowledgeable about technology. So, we put it in the simplest and most basic way we can.

The only solution to this dilemma is to use a C-wire adapter. Now, you might have one at home or you could purchase one from the local electronic store from your location.

When you secure a C-wire adapter, here’s the step-by-step guide on how you can fix it.

NOTE: Make sure to perform precautionary measures before doing this process. It involves electricity and wires, so wear non-static gloves while doing the procedure.

Step #1: Turn the Thermostat’s Power Off

The first thing you want to do is to turn the thermostat’s power off. You can turn it off easily by going into Mode > Off.

Alternatively, you can also control it using the Google Nest Thermostat app by going to the home screen. From there, select your thermostat and go to Mode > Off.

Many people choose the latter because it’s easier and they just need to toggle it in their smartphones!

That is the process of how you can turn your Google Nest Thermostat’s power off.

Step #2: Open the Thermostat and Locate “Common”

After you make sure that it’s turned off successfully, the next thing you want to do is to open the thermostat by carefully pulling the stainless-steel ring along with the LCD Display.

When you pull that off, you’ll see the wires that make the thermostat work and function. You should see the RH, Y1, Y2, G, C, *, etc.

For this process, we just must focus on the “C” wire.

Step #3: Connect the Wires to the C Terminal

You will see that the “C” or the common wire is not connected. This is what’s causing the “delayed” message to appear on your Nest Thermostat.

So, what you must do is plug in and install a C-wire or a common wire to that port. For this method, though, you will also have to toggle the common port on the furnace.

But, with a C-wire adapter, you just must plug it into a wall outlet and connect it to the common port.

Step #4: Plug the Adapter Into a Wall Outlet

Using the C-wire adapter, you just simply must plug it into the wall outlet, then connect the C-wire or the common wire to the port on the Nest Thermostat.

That’s it! That’s how easy it is to use a C-wire to get rid of the delayed message that your Nest Thermostat is giving you.

With this method, you will easily be able to get rid of the “delayed” message on your thermostat in less than ten minutes!

I Can’t Find a C-Wire Adapter, What Are My Other Options?

What if I don’t find a c-wire adapter? What if I can’t secure a specific C-wire adapter to my thermostat?

Method #1: Use an HVAC Wiring Extender

Another option that you can take is to use an HVAC wiring extender to add a common (C-connection) to your thermostat.

For this process, it’ll be best to contact a local HVAC expert to help you with it. This is because you would have to meddle with your furnace and connect a couple of cables to it.

Method #2: Manually Add a C-Wire

The second and the last option you can take is to contact a professional to help you with it.

This process might seem tedious, but it’ll actually take care of the problem indefinitely, just like how a C-wire adapter would. If you’re knowledgeable in toggling or modifying HVAC systems, then, you can do it yourself.

It will involve turning the furnace off, going to the board to connect the C wire, then rewiring it to the “C” port or the common port on the thermostat.

Akin to using an HVAC wiring extender, adding a C-wire to the furnace’s board would require experience and knowledge.
