The wireless controller Salus RT-520RF from a well-known company is a product that has been continuously improved. The Salus RT-520RF temperature controller is a response to the growing market demand and offers quick and easy room temperature control. The OpenTherm communication (OT + 4.0) allows the boiler and the controller to maintain mutual communication. The wireless controller features many practical functions that help adjust the heating level to individual needs. The RT-520RF driver works with devices that use the OpenTherm protocol.

An interesting feature of the RT-520RF controller is the additional power-free contact, which can also be connected to a non-OpenTherm heating device. The set of the RT-520RF device consists of a transmitter and a receiver that can be connected to the heating device, which we can install in another room. Another characteristic of the RT-520RF controller is the setting of maximum and minimum temperatures with a PIN code. This is an ideal solution, for example, when renting a house. Tenants can only change the temperature in areas where the temperature has been pre-set.
