Manufacturer instructions
The Stiebel Eltron RTA-S UP is a flush-mounted room temperature controller designed for precise heating regulation. Installation must be performed by a qualified professional in accordance with local electrical regulations. The unit is typically mounted in a standard flush-mounted wall box. Electrical connections involve wiring the controller to the heating system's actuator or boiler interface; ensure the power supply is isolated before beginning any work. Once mounted, the device allows users to set the desired room temperature via the integrated dial.
