Siemens RDD Series Digital Room Thermostat (RDD310/MM, RDD50.1, RDD100.1RF)
Siemens RDD Series Digital Room Thermostat (RDD310/MM, RDD50.1, RDD100.1RF)
The models in the Siemens RDD series are room thermostats with a digital display and precise temperature control. The RDD310/MM is powered at 230 V and flush-mounted in a wall box; the RDD50.1 is battery-powered; the RDD100.1RF communicates wirelessly (433 MHz) with its receiver.
The thermostats use a relay output to control a combi boiler, zone valve or thermal actuator; compatible products are listed below.

This list is verified compatibility information based on Siemens product matching data; it is not a list of similar-product suggestions. You can make the final selection with our engineering team based on your project conditions (differential pressure, stroke, control signal).
Selection and installation notes
- The thermostat must be selected to match the voltage and output type of the device it controls (combi boiler, actuator, fan coil).
- For accurate sensor readings, the thermostat is mounted approximately 1.5 m above the floor, away from direct sunlight and heat sources.
