Nest Thermostat Delayed – What is It? How to Fix It?

Is your Nest thermostat flashing an irritating “Delayed” message, causing disruptions in your home’s heating or cooling? Don’t worry, whether you see a countdown or a simple “delayed” notification, as there are solutions to this problem. In this article, you will find practical solutions to fix the Nest Thermostat Delayed notification.

For the unaware, Google Nest created the Nest Thermostat, a smart thermostat. It is a Wi-Fi-enabled electronic, programmable, and self-learning thermostat that optimizes heating and cooling in homes and workplaces to save energy. It is based on a machine learning algorithm that requires users to regulate the thermostat for the first few weeks in order to supply the reference data set.

The thermostat can then learn people’s schedules, the temperatures they prefer, and when they like them. When it detects that no one is at home, it can switch into energy-saving mode using built-in sensors and phone locations.

What Causes Nest Thermostat Delayed Message?

The Nest Thermostat Delayed notice or message indicates a power outage. Except for the latest iteration, the “Nest Thermostat,” which utilizes AAA alkaline batteries, the device is powered by rechargeable lithium-ion batteries. This distinction can be confusing at times.

When there is a power outage, the Nest backup batteries take over to protect your device’s data and settings. However, when these rechargeable batteries diminish, your Nest may begin to malfunction, with the “Delayed” notice being one of the first indicators.

Nest Thermostat Delayed Fixes

Force Close the Nest App

The Nest app’s constant pinging of the thermostat may overburden the device’s battery, which may be running low. Even if the app is running in the background on your devices, it can still transmit commands to the IoT device. This is especially true if a “C” wire to charge the battery is not available. Force-closing the Nest app will solve the problem in this scenario. Here’s how you can do it to fix the Nest Thermostat Delayed notification:

Step 1: Long-press the Google Nest or Google Home app icon and select the ‘i’ icon or App Info.

Step 2: On the App Info page, tap on Force Close.

Step 3: Check to see if the Nest Thermostat Delayed message has been fixed or not.

Restart the Nest Thermostat And Any Associated Equipment

If the heating or cooling system is not in the condition specified by the Thermostat, the device will experience delays. Restarting both the Nest thermostat and your heating/cooling system will cure the problem. Here’s how you can do it to tackle the Nest Thermostat Delayed message:

Step 1: Go to Settings on the Nest Thermostat, then select Reset.

Step 2: Select Restart and, after completely switching up, turn off the relevant circuit breakers to remove power to the entire equipment.

Step 3: Wait for a moment and then restart again. Now, your Nest Thermostat Delayed issue should be fixed.

Use Heat or Cool Mode

The Nest thermostat will do its best to maintain the equipment within the chosen temperature range when in Heat or Cool mode. This mode is appropriate in hotter climates when cooling during the day and heating at night are required.

However, if your appliances often move between heat and cool modes, the thermostat will add a delay to protect your device. You may extend the distance between your temperature ranges to prevent shifting between modes frequently. Here’s how you can do it:

Step 1: Open the app, select the Thermostat, and open the Mode.

Step 2: Select Heat or Cool mode (but not Heat Cool mode), and your issue should be fixed.

Note: These actions can also be performed on the Thermostat itself.

Disable Home/Away Assist

The Nest Thermostat is energy efficient thanks to the Home/Away Assist feature. It senses that you are not at home and, as an outcome, decreases the cooling or heating until you return.

If the Nest thermostat fails to identify your presence, you will notice a delay. This could have happened as a result of a bug in the device’s firmware modules or a feature misconfiguration. In these situations, switching off the Home/Away Assist feature would be adequate. Here’s how you can do it to fix the Nest Thermostat Delayed notification:

Step 1: On the Nest app, go to Home/Away Assist.

Step 2: Turn off the toggle next to it to disable it.

Once you do, check whether the Nest Thermostat Delayed message is fixed or not.

Charger Your Nest

Luckily, there is a simple short-term fix to get your Nest thermostat back on track and eliminate the Nest thermostat Delayed message. To begin, take the following steps:

Step 1: Detach the Nest thermostat display with care.

Step 2: Find and locate the USB port on the device’s upper back.

Step 3: Depending on the model, determine which type of USB charging cord your Nest requires (micro-USB or mini-USB).

Step 4: Connect the USB cord to a specialized wall charger (do not use the USB port on a computer or another device).

Step 5: Check if the Nest’s LED indicator is blinking red, confirming a successful charge.

Step 6: Charging times may vary, but they should not exceed one or two hours. If it takes longer, there could be a problem.

Step 7: When the Nest is fully charged, the display panel will prompt you to reconnect it to the base.

Connect a C-Wire to Your Nest and Furnace

The thermostat draws a small amount of power from either the heating or cooling wires in many Nest systems. However, these lines may not offer enough power in some instances, requiring the use of a Common wire (“C wire”).

Step 1: Before beginning, go to your Nest’s Settings and scroll down to Equipment.

Step 2: The Nest will show you the cables it detects in real-time. The yellow wire represents cooling, the white wire represents heat, the green wire represents the fan, and the red wire represents power. The blue wire that plugs into “C” is the one you’re looking for. To power your Nest, the Common wire or “C” wire needs a small quantity of low-voltage power from your furnace. If you don’t see a blue Common wire on the Nest display, proceed to the next step.

Step 3: Turn off or unplug the circuit breaker that controls both the Nest thermostat and your furnace.

Step 4: Open the Nest’s display casing and investigate the cables. Among the connected wires, look for a concealed blue Common wire.

Step 5: Proceed to your furnace if you find the Common wire.

Step 6: Locate the motherboard with the low-voltage wires inside the furnace. For access, you may need to remove a metal panel and a few screws.

Step 7: There are two main wires with off-shooting wires among the low-voltage lines. One of these main wires has five branching wires, one of which is the blue Common wire.

Step 8: Even if another wire is already attached, connect the blue Common wire to the “Com” connector on the motherboard.

Step 9: Return to the Nest, ensuring that both the furnace and the Nest are turned off. Connect the blue Common wire to the Nest’s “C” port.

Step 10: Reconnect the furnace and the Nest, replace the Nest display cover and go to Settings to validate the presence of the blue C wire on your Nest.

Once you do, your Nest should now receive a steady power supply and the Nest Thermostat Delayed issue should be fixed.

Conclusion: Nest Thermostat Delayed

In conclusion, the Nest Thermostat performs efficiently when provided with steady power, which a C wire can offer. If you’re not sure how to troubleshoot or are uncomfortable with remedies, try contacting a local Nest Pro who can diagnose and address power issues, including the installation of a C wire or its accessory, such as a Nest Power Connector, to guarantee your Nest thermostat works perfectly.
