According to our information, this is generally possible; however, your Danfoss Link CC central controller must be Wi-Fi enabled, as older models without Wi-Fi are not compatible. Furthermore, it is mandatory that software version 4.2.1355 or higher is installed on the central controller.
Hello Philippe
The thermostat CF-RS 071SU-01A-24 does not ring a bell. The best thing to do is to check the Danfoss website or the manufacturer's website for replacements. I personally had to replace a Room Sensor DRS11 from Danfoss with the Icon 620875.
I hope I have helped you anyway. Kind regards Werner
