Siemens RDH100 Electronic Room Thermostat (Wired / Wireless Set)
Siemens RDH100 Electronic Room Thermostat (Wired / Wireless Set)
The models in the Siemens RDH series are room thermostats with a digital display and precise temperature control. The RDH100 is a battery-powered thermostat with PID control; the RDH100RF/SET offers the same thermostat as a set together with its wireless 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.
