Mitsubishi vrf lev reset

[Northy303]

Hi,
I am attending a site tomorrow that has a pury p 250 ygma
Vrf that I would like to do an lev reset,
My question is do i just do a total virgin restart and power everything down and switch indoors then outdoors then BC box or do I need to do something else.
I do have have the mnet tool and a laptop, can it be done through that,
Thanks in advance.
Matt.

I'm no Misti expert so take this with a pinch of salt but I thought it's just a case of resetting the power to reset the LEV position.
Virgin reset was to get rid of units no longer on the system or that type of thing?

So went there today, they have a puhy ep 250 ygkma with 14 indoors and 1 x bc box.
All heating and cooling except 1 x compact cassette,
Reset levs by unplugging mnet and powering up, and did a virgin restart of system, still no heat, plugged in mnet monitor tool got th2 is hotter than th3 ? Sv b in bc box shows open,
Took a screenshot of readings this is what it did for 2 hours and didn't change.
