SALUS RT520RF wireless room thermostat battery powered programmable weekly surface mounted white Open Therm

Comfort and savings in your home

The SALUS RT520RF temperature controller is a modern solution for precise heating and cooling control in your home. The device combines the convenience of wireless communication, advanced programming functions and compatibility with modern boilers using the OpenTherm protocol. It is an ideal choice for both installers looking for reliable equipment and users who value comfort and savings.

Functionality and possibilities

The RT520RF consists of two elements: a transmitter mounted on the wall and a receiver installed near the controlled device. Wireless communication ensures easy installation and flexibility in choosing the location. The controller allows you to control the heat source or circulation pump, and thanks to the OpenTherm protocol, it provides two-way communication with the gas boiler, which translates into optimized energy consumption.

The device offers a range of features that increase user comfort:

• Weekly schedule: Allows you to set individual temperatures for each day of the week, tailored to your lifestyle.
• Frost protection: Automatically turns on the heating when the temperature drops below 5°C, protecting the installation from damage.
• Vacation mode: Allows you to set a constant, lower temperature during a longer absence, reducing heating costs.
• Control algorithm selection: Choose between the TPI (Time Proportional & Integral) algorithm for precise regulation or hysteresis for simpler control.
• PIN lock: Protects settings from unauthorized changes – useful, for example, when renting a property.

OpenTherm technology and compatibility

The OpenTherm protocol is a communication standard between controllers and boilers, which enables precise control of the heating device's power. This allows the boiler to adapt its operation to current thermal needs, which translates into greater energy efficiency and lower heating bills. The RT520RF is compatible with a wide range of boilers using this standard. Additionally, it has a NO/COM dry contact enabling cooperation with devices that do not support OpenTherm.

The controller is powered by two AA batteries, and the receiver requires a 230 V AC 50 Hz power supply. The temperature measurement range is from 5 to 33°C, and the radio range reaches up to 100 meters in open space. The maximum contact load is 16 A, and the degree of protection is IP30. The output signal can be OpenTherm +4.0 or NO/COM (dry contacts).

The RT520RF is an investment in comfort, savings and modern heating solutions. Thanks to its easy installation and intuitive operation, the controller will quickly become an indispensable element of your smart home.
