The Nest thermostat delayed a reliable option for controlling the temperature in your home. This device helps track energy consumption and keep a comfortable temperature in your living space.
Are you concerned because your Nest Thermostat is delayed? Identifying and Understanding a Nest thermostat issue can be difficult, and resolving it can become a nightmare.
The nest thermostat display shows the Delayed Notification on its screen.
Nest Thermostat customers experience this problem frequently and often ask about it. You can find out the answer by reading the full article.
We’ll explain what it means and how you can resolve it hassle-free.
Why Does My Nest Thermostat Say Delayed?
There are multiple reasons for the nest thermostat being delayed, which are enlisted below:
- Your Nest Thermostat Has Been Recently Installed
- Battery Life Issues
- You Recently Rebooted Your System
- The wiring circuit is malfunctioning
Your Nest Thermostat Has Been Recently Installed
When you install a brand-new Nest thermostat in your home or office, its temperature sensors will take some time to adapt to the new environment.
This is why the Delayed message appears. Aside from that, you cannot predict how long it will take to settle in before it can perform optimally.
So, it takes some time to perform its actions, and you don’t need to worry about it. Automatically, the Nest thermostat adjusts to the surroundings of your residence or workplace as soon as it is given enough time.
Nest Thermostat’s Battery Issues
One of the other reasons for your Nest thermostat to display delayed messages is because of battery drainage.
The Nest thermostat takes a while to start up if the battery inside isn’t sufficient to power it.
Furthermore, the thermostat has a lithium-ion battery that gets power from the HVAC system. The HVAC system and battery will not operate if the battery is drained.
You Recently Rebooted Your System
A delayed message will appear on the nest thermostat once you reboot the system.
Rebooting your Nest will wipe all the saved data, so it has to learn your home again as if it were a brand new one.
Eventually, the delayed message will disappear as the system gathers data about the area around it.
The wiring circuit is malfunctioning.
Nest thermostats run on HVAC (Heating, Ventilation, and Air Conditioning). You must ensure your Nest thermostat is wired correctly between the HVAC and Nest. In case of wiring issues, the Nest will give you a delayed notification.
If you navigate the settings on your Nest thermostat, you can see where the wiring is.
How to check the wire in the Nest thermostat?
To check your Nest thermostat’s wires, follow these steps:
- Open the setting option and click on it.
- Scroll it until the Equipment option appears on the nest. Now tap on it.
- Now you will see the following wires: Y1 (Yellow wire) for cooling, W1 (white wire) for heat, G (green wire) for the fan, RH (red wire) for power, and C (blue wire) for the common wire.
- When the display shows without the C wire, you must connect the missing C wire (in blue color) for it to work.
How to Fix the Nest Thermostat Delay?
A Nest thermostat can get a ‘Delay’ notification if it contains a power issue. Unlike some older thermostats, the Nest thermostat contains rechargeable lithium-ion batteries that cannot be removed.
The Nest device cannot receive sufficient power if there’s a wiring issue or a missing C wire.
The most common fixes for a Nest Thermostat being delayed are:
- Check if the Nest Thermostat Is Newly Installed
- Make Sure The Battery Is Charged.
- Update the Software
- Check If A C Wire Is Connected
Let’s start things off by checking if the thermostat is Newly Installed
Check if the Nest Thermostat Is Newly Installed
As discussed above, newly installed Nest thermostats may need time to optimize how your house heats and cools.
When your device displays ‘Delayed for 2 Hours’ or another timescale, wait a while, and then it will resume its usual functions.
In the same way, if you reset Nest recently, Nest will send you a delay notification.
The device has been wiped off all its info about your house. As a result, you’ll need to wait a couple of days for it to get back on track.
Make Sure The Battery Is Charged.
You can manually charge the battery with a USB cable if the Nest thermostat’s battery runs out and the HVAC system does not generate enough power.
Follow these steps to accomplish this:
- On the wall, remove the front cover to expose the micro-USB port.
- Connect the device to a compatible charger and let the internal battery recharge for some time.
- Once it’s been left for a while, simply replace the Nest’s front, and you shouldn’t see the ‘Delay’ message anymore.
Even though this is an immediate fix, it won’t solve the ‘Delay’ problem permanently. Due to the lack of power provided by the HVAC system, the battery will need to be recharged regularly.
Update The Software
All modern gadgets, including Nest thermostats, run better with frequent software updates.
It could be that an update is interfering with the regular function of your device if it displays the ‘Delay’ notification.
It’s normal to get ‘Delay’ alerts, so just wait for it to finish updating, and it will begin to function smoothly once more.
Check If A C Wire Is Connected
Nest’s Thermostat is powered by a constant flow of 24 volts AC through the C-wire or ‘common wire’.
Consequently, it is mandatory to connect common wires to the thermostat; otherwise, Nest thermostats will be delayed.
In addition to the R wires, the C wire connects the smart thermostat to the HVAC system. This is what keeps the Nest thermostat running 24 hours a day.
How to Install C Wire
The C-wire of a Nest Thermostat can be installed in the following ways:
- Connect the C wire to the thermostat terminal on the HVAC system.
- Replace the C wire with the Fan (G) wire.
- A C-wire adapter should be installed.
Note: C wire installation is complicated, so hiring a professional for this job is advisable.
Connect The C Wire To The Thermostat Terminal On The HVAC System By Yourself.
This is a cost-effective option if you are skilled at running the wiring and installing it yourself. If not, we recommend getting a pro to do the work below.
Moreover, your nest’s proximity to your HVAC system will influence how complicated this is.
Running wiring through the entire home can be daunting if your HVAC is upstairs and your thermostat is downstairs.
If you choose to install the new C-wire yourself, here are the basic steps:
1st method: Determine the wiring route
Start by determining the route the wire must take to reach the Nest thermostat from the HVAC system.
You may just need to drill one hole in the wall. Otherwise, you’ll need to map out a route, which will be a bit longer within your house.
2nd method: Connect the C Wire to the Nest Thermostat
- The wire must be pulled into the thermostat and hooked to the appropriate terminal.
- Make sure the wire isn’t tangled or kinked.
- It will be necessary to pull it through the device and pass the other end through the walls to the HVAC system.
- Through difficult-to-reach places, feed the wire with wire rods.
3rd Method: Connect the C Wire to the HVAC System
After pulling the wire and reaching the HVAC equipment, connect the wire to the appropriate terminal to close the circuit.
- Take the cover off and Unplug the HVAC system or press the circuit breaker switch to turn it off.
- Identify the thermostat terminals W, R, G, Y, and C.
- Connect the pulled nest thermostat’s C wire to the HVAC board’s C terminal.
- Activate the HVAC system, and attach the front cover.
- The Nest Thermostat needs to be configured according to its settings.
- Lastly, return to the Nest Thermostat and see the C wire connected in your device’s ‘Equipment’ menu to ensure that the C wire is installed and plugged in properly.
When you install the C wire on your Nest thermostat, it’ll get a continuous power supply from the HVAC system. Therefore, it no longer shows the ‘Delay’ notification.
Install a C Wire Adapter:
You don’t need a professional to install a C wire adapter. You can do the installation process by yourself independently:
- Take off the front of your Nest Thermostat to access the wiring terminals.
- There are two wires connected to the adapter. Attach one cable to the Power (RH) terminal and a second to the Common (C) terminal.
- Now attach the adapter plug to the nearest power socket in the wall.
Replace The C Wire With The Fan (G) Wire.
There’s a green wire called the G wire that controls the fan. Using it, you can fool the thermostat into thinking a C wire is installed.
Here’s how you can do it:
- First, turn off your HVAC system and remove the thermostat’s front panel.
- Then, connect the G wire to the C terminal by removing it from the G terminal.
- Now return to the HVAC system terminals and repeat the process.
- Once the system is on, go back to your Nest thermostat’s settings menu and proceed with the setup.
Note: This solution will restrict your ability to operate your fan on its own, either to heat or cool.
Nest Thermostat is an ingenious device that minimizes energy usage and keeps your home at a comfortable temperature.
You shouldn’t be concerned if you receive a nest thermostat delayed message. There may be various reasons, like if it’s newly installed, if it’s been rebooted, or if there’s a problem with the C wire.
We have covered almost all fixes if any of these problems occur. Usually, no fix is necessary, and you must leave your nest to learn about your surroundings. Fortunately, you’ll rarely need to complete the circuit if the C-wire isn’t connected to the Nest thermostat.
