Air Source Heat pump water Heater unit problem

Hi All
I have just turned on the small LCD control panel for our Under floor heating in a small cottage and an error code came up and the system is not working.
The users Manual says that the error code E10 is a "Controller communication error''It could also be a "Coil Temp sensor error" as I am unsure if it's a E1 or E10 error flashing.

We are living in France and as all the user manuals are in English and I think that the previous owners had a UK firm install the Heating system so I am really worried that it could be a nightmare getting a French company to fix it fast as it may just be a simple fix.
I believe the Heater is a Kings RS-62F5A/T unit.
Any help in the right direction would be much appreciated.
Thanks,
Mick

The only make I could find with the RS-62F5A/T reference was Kings,nothing with ******.
Unfortunately we are the colder side of France and in Normandy so the Riviera Link is further away than the UK but thanks anyway.
I really think it is a simply fix and not a part problem and just hoped someone who have a idea of the error code who know these systems.
Everything was working fine until I tried to adjust the Temp on the LCD control and it just shut down when I pressed the reset.

 

Thanks KIAB
Happy to say it's all working now.....a small cable had come off on the back of the LCD control that was not done up.
Such a simply thing.
