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.
