## Questions & Answers

**Q: Is this suitable to control a dehumidifier/air heater in a swimming pool house?**
A: No

**Q: Is the newer rdh100 thermostat compatible with the older rcr10 receiver? 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

### ⭐⭐⭐⭐⭐ easy
*by A***R on 27 January 2025*

Superb instant pairing

### ⭐⭐⭐⭐⭐ Excellent
*by J***Y on 13 September 2024*

Ordered as old one was playing up, was told by heating engineer i had to buy both sender and receiver as they are paired as a unit. I fitted my sender first and tried to pair with old receiver, it worked straight away so i now have a spare new receiver. Works well, had it now over 12 months.

### ⭐⭐⭐⭐ Good Display
*by M***. on 30 October 2024*

Very good display, easy to use with a simple layout. The instructions could be better for example virtually no explanation of how the PID modes function.
