How to Use Sleep Mode on Your Air Conditioner

Tired of waking up in the middle of the night feeling too cold? Or shocked by rising power bills during summer? If yes, you're not alone. Many people leave their air conditioners running all night for comfort, but don’t realise it’s also affecting their sleep and electricity usage.

That's where the Sleep Mode in Voltas ACs steps in as a smart feature designed for both comfort and energy savings. Whether it's a hot summer night or an afternoon nap, Sleep Mode ensures the temperature adjusts to your body’s needs while reducing power consumption.

Let’s explore how this small but powerful feature works and how you can make the most of it.

What is Sleep Mode?

Sleep Mode is a built-in feature in most Voltas air conditioners. Once activated, it adjusts the room temperature automatically throughout the night.

Here’s what it does:

• Increases the temperature gradually after you fall asleep.

• Maintains a comfortable level of cooling based on natural body temperature drop.

• Saves electricity without disturbing your comfort.
  

This makes Sleep Mode ideal for people who want peaceful sleep and smaller electricity bills.

How Sleep Mode Works

Gradual Temperature Increase

Our body’s temperature lowers naturally when we sleep. The need for intense cooling reduces as the night progresses. Sleep Mode accounts for this change.

When you activate Sleep Mode, the AC increases the temperature by 1°C every hour for up to 2 hours. For example, if you set the AC to 24°C, it will adjust itself to 26°C over time. This happens quietly, without waking you up.

Reduced Load on the Compressor

As the AC raises the temperature gradually, the compressor doesn’t have to work as hard. This is especially beneficial when using high-efficiency models like a 1.5 ton 5 star AC, which already consume less power and work best with features like Sleep Mode. This means fewer cycles, less wear and tear, and a longer lifespan for your AC unit. It also cuts down on your electricity usage significantly.

How to Activate Sleep Mode in Voltas AC

Activating Sleep Mode is easy, whether you're using a basic remote or a smart Voltas AC with app connectivity.

Using the Remote

Most Voltas AC remotes have a dedicated Sleep Mode button. Here’s how to use it:

1. Turn on your Voltas AC.
   

2. Press the Sleep button on the remote.
   

3. A sleep icon or “SLP” symbol will appear on the display.
   

That’s it! Your AC is now running in Sleep Mode.

Using the Voltas Smart AC App

If you own a Voltas smart AC, you can control Sleep Mode from your smartphone.

1. Open the Voltas Smart app.
   

2. Connect to your AC via Wi-Fi.
   

3. Tap on the Sleep Mode option in the app interface.
   

4. Set a duration or schedule as per your needs.
   
   

This is useful if you forget to activate the mode before sleeping.
