    "In the coldest weather, my average daily natural gas consumption was around 8.7 m³. After the installation, it dropped to around 5.2 m³. I also live on the top floor. I think its effect would be even greater on intermediate floors. It's worth the money. 5 stars aren't enough—I’d give it 10."

Frequently Asked Questions

Which heaters/boilers and air conditioners is Cosa compatible with? Will it work with my device?

Cosa makes your home's heaters and air conditioners smart, providing comfort and energy savings. The compatibility criteria based on your device type are specified below: Heater / Boiler Compatibility: Cosa is compatible with all heaters/boilers that feature a room thermostat input and operate via on/off control logic. Air Conditioner (AC) Compatibility: Cosa is compatible with residential air conditioners whose remote control features a digital display screen. However, even if the remote has a screen, AC models whose power-on and power-off commands are not separate (i.e., operating sequentially with a single toggle button) are not supported. 💬 Not Sure About Your Device's Compatibility? If you would like to confirm whether your current device is compatible with Cosa, you can forward the following details to destek@smartcosa.com: For boiler/heater compatibility check: The brand and model of your heater/boiler. For AC compatibility check: The brand and model of your air conditioner, along with a clear photo of its remote control. Our team will be glad to carry out the necessary checks and assist you.

What is the warranty period for Cosa?

Cosa products come with a 2-year warranty.

Can other family members in my household use the same Cosa? How do I share home access?

Yes, other family members can also control Cosa from their own smartphones. Simply follow these steps to share access to your home: Go to the "Home Settings" menu under the settings for the relevant home in the app. Tap the "Invite a New User" option and enter the email address of the person you want to add. Once the invited person downloads the app and registers (or logs in if they already have an account), they must accept the invitation displayed on their screen.

My combi boiler is still under warranty. Will installing a Cosa void my combi boiler's warranty?

Provided it is connected correctly, the Cosa room thermostat will certainly not damage your boiler. Some boiler manufacturers may void the boiler warranty if room thermostats are installed by an unauthorized service. Therefore, even if Cosa would not harm your boiler's warranty, installing Cosa to your boiler by an unauthorized service may void your boiler's warranty. We advise you to consult your boiler's manufacturer regarding this matter.
