Ie can I just replace the thermostat and synch it to my existing receiver?** A: dont known replace both they always come as pair **Q: Has the rdh10 rf been replace by rdh 100 rf** A: Yes, the RDH100RF is the newer version. **Q: Will the Siemens rdh100-rf wirless room thermostat and receiver fit easily to a valiant eco tec plus** A: The receiver unit needs mains power and has a 2-wire connection that replaces the output from a mechanical thermostat. Typically you mount it next to a programmer and connect it into that. If your boiler has an integral programmer you have to be able to identify the correct wires to connect to the receiver. "Easy" depends on your level of competence. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great simple wireless thermostat. *by M***W on 21 November 2025* If you are frustrated by over complicated multi time period wireless thermostats this is the one to buy.
