I have a rdh10rf control unit and want to upgrade to this unit. is this compatible with my rcr10/433-gb receiver

I ended up sending this back as it wouldn’t sync to the transmitter already next to my boiler. Ended up having to buy a new receiver and transmitter.

Is this compatable with rdj10rf receiver? the receiver is already installed and working. our rdj10rf theromostat is broken, but receiver is still ok.

It replaced a thermostat which was not a Siemans model

Does this models screen light up?

Don’t know as I had to send it back. It appears that just buying the thermostat was not an option. I got a heating engineer to source me a new thermostat and transmitter and fit it for me.

What are the correct dimensions? The ones listed are the size of a shoe box!

It is 120mm high, 90mm wide. 26.9mm deep.
