Ferroli Romeo W RF OpenTherm thermostat "NoCN" or "NoCM" error?
So you got a Ferroli Optimax bolier with the built-in programmer/clock and you are replacing it with this ROMEO W RF wireless OpenTherm thermostat:
You've connected the RF bridge, powered up the room unit and got RF comms going, but you get a fat "F" or "E" fault codes displayed on the room unit and the built-in programmer/clock displays "NoCN" or "NoCM":
The Ferroli manual doesn't tell you to disconnect the programmer/clock after installing the RF bridge. To fix the problem, disconnect the programmer/clock by pulling out the wiring loom going to the back of the clock out and leaving it disconnected.
Note: if you also want to control your boiler from your phone/Internet, read the following

Hi,
Just wondering where you bought this thermostat from? I can't seem to find it anywhere!
Any info would be great,
Cheers,

I got mine from Russia, since it is not available in the UK for some strange reason...

I got it forwarded by a relative over there. There are Polish stores selling it also, possibly mail-order. Have a look using the P/N below:
