The Nest Learning Thermostat makes monitoring your energy usage and finding the perfect temperature for your home a breeze. However, if the system is not working properly, it can be difficult to pinpoint the issue since this is such new technology.
One issue you may come across with the Nest Thermostat is that it says “In 2 Hours” on the digital reader. This two-hour notification delays the AC power, which may make your home an uncomfortable temperature in the process.
Luckily, this issue is really easy to rectify, and it will likely fix itself depending on the cause for it. To find out what this notification means and what you can do to fix it, keep reading.
Why My Nest Thermostat Says “In 2 Hours”
If your Nest Thermostat says, “In 2 Hours,” it means that the thermostat is delayed for cooling your home. This will occur whenever the temperature is currently at one level, but you want to change it to make the home more comfortable. For example, the thermostat may say that it takes 2+ hours to cool the house from 75 degrees Fahrenheit to 73 degrees Fahrenheit.
There are three main reasons why your Nest Thermostat will say this. The thermostat has been recently installed, you did a system reboot, or the circuit is not completed. Let’s take a look at each one of these causes to fully understand what is happening with your Nest Thermostat.
It Has Been Recently Installed
You would be furious if your teachers in high school expected you to learn newly taught material in an instant. It is simply not possible for our brains to automatically process and apply material if we have only recently learned it. The same is true of your Nest Thermostat.
Whenever your Nest Thermostat is first installed, it doesn’t yet know how quickly or long it takes for your home to cool down. As a result, a recently installed Nest Thermostat may say “In 2 Hours” simply because it doesn’t yet have the information it needs to give you a more exact estimate.
If your thermostat was just installed, this is almost guaranteed to be the source of the delayed time. There is nothing wrong with your Nest Thermostat. You just need to be patient so that it has the time to learn about your home specifically.
You Did a System Reboot
If you did a system reboot, the reason for this delay time is the same as above. The system simply needs to relearn the specifics about your home and its energy usage. In fact, this delayed time is to be expected every single time you reboot your Nest Thermostat.
The Circuit Isn’t Completed
Finally, the last reason that your Nest Thermostat has a delay is that the circuit is not completed. Unlike traditional thermostats, the Nest is not battery-powered. It requires access to your furnace to get adequate power. As a result, the Nest needs one additional wire that many people forget to use.
To check whether or not the circuit is complete, go to your Nest and scroll over to settings. Under settings, click equipment. If the Nest is wired correctly, there should be a little tab next to the Y1 for your cooling system, G for the fan, W1 for the heat, RH for the power, and C for common.
Whenever the circuit is not complete, there will only be tabs next to Y1, G, W1, and RH. There will not be a tab next to C. This tells you that you do not have the additional wire to complete the circuit.
What to Do About It
Knowing what causes the message isn’t enough to fix it. Here’s what to do:
Wait It Out
If the delay is because you have just recently installed or rebooted the Nest Thermostat, all you have to do is wait it out. The system is learning your home, and that can only happen with time. Once your system learns how quickly your home cools down, this delay should disappear on its own. It also may cool down quicker than 2 hours.
Complete the Circuit
If the delay is caused because you do not have the additional wire, you will need to complete the circuit. This is a bit more difficult to do, but anyone can do it with the right instructions. Here is what to do:
- Turn off power to the furnace.
- Check to see if there is an extra wire in the Nest. It will be blue. There should be one.
- Grab a flashlight or headlight (preferred), a regular standard and Phillips screwdriver, a respirator, and 6-in-1.
- Go to the furnace and double-check the furnace is unplugged. Take off the cover. The wires may be in the lower system. You may need to use the 6-in-1 to remove the cover of this back portion.
- Find the wire that goes to your thermostat. This large black wire will have multiple wires in it, whereas the AC will only have two.
- Find the blue wire inside the thermostat wire and attach it to the plug that says “C” or “Comm” for “Common.” Close the furnace, but leave it unplugged.
- Go to the Nest and plug the blue wire into the “C.”
- Finally, plug the furnace back in and test it out to see if it works correctly.
Final Thoughts
A Nest Thermostat is helpful for regulating the temperature and energy usage in your home. If you see a delay that says, “In 2 Hours,” it is likely because you have only just recently installed or rebooted the thermostat. Luckily, you don’t have to do anything if this is the cause since the Nest will learn how quickly your home cools.
However, you may need to complete the circuit if you did not connect the Nest Thermostat to the common wire. This is pretty easy to do, but you need to make sure to have the right tools and safety tips in mind to keep yourself safe while fixing the issue. We hope this helped!
