Hitachi Utopia RAS4 HRNE

Hello people,
Does anyone have the method to set up auto restart after power failure, for this system please. Utopia RAS4 HRNE, (R410a). I've searched previous threads, without success, and i phone Hitachi - where as usual there's no one available to answer the question. Any help would be appreciated.
Regards,

The Utopia & Set Free VRF indoor units are all the same.

For all of them its a setting at the remote controller.

1/ engineers service mode 1
2/ fuction d1 for power supply on/off or d3 for restart after power failure but will restart in off mode if unit was off at time of power failure.

For some optional fuction settings you have to scroll through the indoor address to display AA.

Thanks for that Thermatech, i managed to get an answer out of Hitachi eventually, after the first techi gave me the wrong info. But thanks all the same, i'm sure others will find this info usefull too.
Cheers. Andy C
