Wired temperature controller SALUS RT520 battery-powered programmable weekly surface-mounted white

Comfort and savings with the SALUS RT520 controller

The SALUS RT520 temperature controller is a modern solution for precise control of heating and cooling in your home. Designed for both installations with traditional boilers and systems using the OpenTherm protocol, it provides thermal comfort and allows you to reduce operating costs. Thanks to its intuitive interface and wide programming options, the RT520 controller will adapt to your individual needs.

Functionality for professionals and users

RT520 is not only comfort for the end user, but also a tool that makes the work of installers easier. Compatibility with OpenTherm (OT+ 4.0) enables two-way communication with the boiler, which translates into efficient power control and optimization of the entire heating system. The ability to choose between the TPI algorithm and hysteresis allows you to adapt the controller's operation to the specifics of the installation and user preferences. Additionally, the service mode protected by a PIN code ensures protection of settings against unauthorized changes.

Key features and benefits

• OpenTherm communication: Two-way communication with the boiler ensures precise power control and maximum efficiency of the heating system. Automatic detection of OT+ 4.0 protocol simplifies installation and configuration.
• TPI algorithm: The intelligent control algorithm analyzes the heating and cooling rate of the room, providing a stable temperature without fluctuations and minimizing energy consumption. Three TPI modes available: for radiators, underfloor heating and electric heating.
• Programmable schedule: The ability to set an individual work schedule for each day of the week allows you to adjust the temperature to your lifestyle and needs.
• Boost mode: Quickly increase the temperature in the room for a specified time – an ideal solution when you need quick thermal comfort.
• Vacation mode: Maintaining a minimum temperature during your absence – protection against freezing and energy saving.
• PIN lock: Protection against unauthorized changes to settings – useful in the case of property rental or the need to limit access to temperature regulation.
• Clear LCD display: A large and clear LCD display makes it easy to read information about temperature and controller settings.
• Wide adjustment range: The measurement range from 5°C to 33°C allows for precise adjustment of the temperature to your preferences.

Installation and compatibility

The SALUS RT520 controller is a surface-mounted device, which means that installation is simple and does not require intervention in the existing electrical installation. Battery power (2 x AA) eliminates the need to connect to the electrical network, which further simplifies installation. The controller is compatible with various types of boilers – both those using the OpenTherm protocol and traditional devices controlled by NO/COM/NC contacts. The ability to control the central heating circulation pump or chilled water expands the scope of the controller's applications to cooling systems.

Power supply: 2 x AA Temperature control range: 5 - 33°C Output signal: OpenTherm / NO/COM/NC Temperature indication accuracy: 0.1°C or 0.5°C Control algorithm: TPI / hysteresis ±0.25°C / ±0.5°C Dimensions [mm]: 118 x 95 x 26

The RT520 controller is an investment in the thermal comfort of your home and energy savings – regardless of whether you are a professional installer or an end user!
