This document introduces the RDD10 and RDD10.1 temperature controllers from Siemens Building Technologies. These products feature a LCD display and provide on/off signal control for the heating system's 2-way valve. The controllers can switch between normal and energy-saving modes, and can be powered by AC230V (RDD10) or DC3V battery (RDD10.1). They are suitable for residential, commercial, and school applications, and can control components such as heat valves or zone valves, gas or oil burners, fans, and pumps.
The Siemens RDD10 is a room temperature controller designed for heating systems. It can operate from AC 230 V mains or a DC 3 V battery pack and provides normal, energy‑saving and stop modes that are selectable via a single button. The device drives heating valves, gas or oil burners, fans and pumps through its relay outputs.
The manual details the controller's hardware layout, installation guidelines (mount at ~1.5 m height, avoid direct sunlight), calibration procedure for the built‑in temperature sensor, and technical data such as power consumption, output ratings and environmental limits. Certification and application examples for residential, commercial and school settings are also included. This manual is written in Chinese.

The RDD10 can be powered from an AC 230 V mains supply (±10/‑15 %) or from a DC 3 V battery pack using two AAA alkaline cells.
Press the two designated keys simultaneously for 3 seconds, then adjust the displayed temperature with the “+” and “‑” keys up to ±3 K; the controller will automatically return to normal mode after 5 seconds.
