Salus RT520: wired programmable room thermostat
The white Salus RT520 lets you set room temperature manually or with a schedule. Its LCD shows the settings. The wall-mounted thermostat uses two AA batteries and has no built-in Wi-Fi. Scheduling helps match temperature to room use; actual energy consumption also depends on heat loss, settings and use.
Check switching and electrical load
The existing Salus product information lists a volt-free contact, OpenTherm support and a maximum relay load of 3 A. Check the load specification in the official manual for the supplied version. The RT520 is not a 16 A thermostat for directly switching an entire electric heating circuit. Have a qualified installer determine whether additional switching equipment is required.
On/off control and OpenTherm serve different applications. An electric infrared panel is not automatically compatible with an OpenTherm connection. For multiple panels, the total load and switching arrangement must be suitable. A room thermostat also does not replace any required floor sensor or floor temperature limiting for electric underfloor heating. Overtemperature protection remains a separate part of the heating system.
Installation and suitable controls
Have the wired connection and settings completed according to the manufacturer’s instructions. Sensor placement affects measured temperature; follow the mounting guidance. Choose Wi-Fi, wireless or plug-in controls only if their functions, receivers and load ratings suit the installation. App control, consumption monitoring and geofencing depend on the model and are not features of this RT520.
