Good morning.
I have a Siemens room thermostat which has two wires inside. I bought a siemans rdh10rf set digital room stat which seemed
I've a good Idea at the time.
I thoughtbit would just be simple taking the old one off and connecting the new one on. However when I connect up the two wires nothing works.
Can anyone assist with some advice please I have attached photos of old and new.
Thanks
