TESLA WiFi SV50

Smart Thermostatic Valve
  • Radiator control via Wi-Fi and the TESLA Smart app
  • Automatic heating schedules + Boost and Holiday modes
  • Open window detection and anti-freeze protection
  • Includes a set of adapters for the most common valve types

Comfortable Temperature, Lower Bills

 

The TESLA WiFi SV50 transforms an ordinary radiator into a smart heating system. Simply set your desired temperature, and the valve maintains it automatically—without unnecessary overheating or constant manual adjustments. The result is a more pleasant indoor climate and more efficient energy consumption. Perfect for both apartments and offices where you want full control over your heating.

Control via Wi-Fi or Manually

 

The valve connects to your home Wi-Fi network (2.4 GHz), allowing you to change the temperature remotely. If you don’t want to reach for your phone, you can adjust everything manually using the control wheel. The clear display shows current settings and modes, with temperature adjustments in 0.5 °C increments.

Modes and Scheduling to Match Your Day

 

You don’t need to heat your home the same way all day long. The TESLA WiFi SV50 offers practical modes and scheduling, allowing you to set temperatures based on when you are home, sleeping, or at work. You can also use the Boost function for rapid heating or Holiday mode, which maintains a baseline temperature during long absences.

Smart Protection for Savings and Safety

 

The valve automatically reacts to common household situations. If it detects a rapid drop in temperature, it recognizes an open window and temporarily limits heating to prevent energy waste. It also features a child lock and automatic anti-limescale protection, which helps keep the valve functional in the long term.

Precise Custom Regulation

 

Every room heats differently, which is why the TESLA WiFi SV50 can be fine-tuned. In the settings, you can choose the regulation method (e.g., smoother control for stable temperatures), adjust sensitivity, or calibrate the sensor so the measured temperature accurately reflects the reality in the room.

TESLA Smart: Control, Automation, and Sharing

 

The TESLA Smart app allows you to manage the valve from anywhere. Set temperatures, create schedules, or set up automations so the heating reacts to the time of day or specific conditions. You can also securely share access with family members, giving everyone their own account and permissions.
