Intelligent scenarios

"Goodnight" Scenario: Automate the temperature in your home to ensure the perfect sleep environment . The thermostatic head lowers the temperature a few degrees before your usual bedtime, creating a cooler, more comfortable environment that promotes healthy sleep. In the morning, just before you wake up, the temperature gradually increases to wake you in a warmer environment, without the need to leave bed for a cool room.

"Coming Home" Scenario: Set your thermostatic radiator valve to automatically raise the temperature in your home an hour before you're expected to return from work or school. This way, you'll feel instantly warm when you enter your home, regardless of the weather outside. This is especially useful on cold days when the difference between indoor and outdoor temperatures is significant.

"Away from Home" Scenario: Activate energy-saving mode when you're away from home for an extended period. The thermostatic head maintains a minimum temperature, preventing temperatures that are too low and could damage plumbing or other home components, while maximizing energy savings while you're away. When you plan to return, easily restore normal settings using the mobile app .

You'll have access to your thermostatic head at any time via the free Tuya Smart app. With it, you can, for example, turn the heating on or off from your smartphone (Android/iOS), change scenarios like intelligently lowering or raising the temperature, enable eco mode when you're away, detect an open window and adjust the temperature accordingly, and lower the temperature during the night .

The intuitive app was designed for the most popular mobile operating systems, Android and iOS, so you can be sure it will be continuously supported and updated. The app's clear and well-thought-out menu makes it impossible to get lost despite its many options and additional features, making everyday use of the thermostatic head simple and enjoyable .
