Siemens RDF510 / RDF530 Flush-Mounted Fan Coil Thermostat
Siemens RDF510 / RDF530 Flush-Mounted Fan Coil Thermostat
The Siemens RDF series are room thermostats with a digital display for fan coil systems. The RDF510/BP provides on/off valve control in 2-pipe systems, while the RDF530 is for 4-pipe systems; both have 3 fan speeds and are flush-mounted.
The thermostat controls the fan coil valve actuator and the fan speed; verified valve and actuator combinations 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.
