Hi Jan,
Sorry doesn't ring any bells atached is he only list i have

Try ringing Space air on 01483 504883.

They have always been very helpful and spot time each time i have rang with a problem

Regards

Raymond

We really do need to know the model type. Is the "emergency" switch in the correct position on the outdoor pcb? factory set is in the "white" area. Any changes to switches must be followed by a power reset.

If you ring Space Air the first thing they will ask for is a model and serial number.

Thanks for the replies, have been in contact with tech support did all the checks they suggested still no joy, model number on my paper work in my van will have to come back on that one thanks

Hi jan.

Daikin is not sold in my country but, in all cases when an AHU started going funny, I've found a wire disconnected in the controls part.

Have a check for a loos wire, who knows, it might be your day. :cool:
