What do you want?

у товарища из Польщи ошибка "OFF BYE MASK"...

Do you speak English?

We want to help you, but here will be some mistakes translating from Polish to Russian using google translator or something more.

Which equipment does it control? I mean PCO2 is programmable controller. You should look for this alarm in equipment documentation.

Translated by google:

Czy mуwisz po angielsku?

Chcemy pomуc, ale tu będą jakieś błędy w tłumaczeniu z polskiego na rosyjski za pomocą Google Translator, czy coś więcej.

Jaki sprzęt to kontrolować? Znaczy pCO2 jest sterownik programowalny. Należy szukać tego alarmu w dokumentacji sprzętu.

All photos here.
I'm using google translation

"OFF by mask" means that unit is swiched off by keypad. It is not error.
You must swich on unit by keypad.
In attached you can find manual for this application.

From main screen you must go to screen M5 (by keys UP or DOWN).
Change parameter "Start-up unit?" on screen M5.

Just looked at photos and ...
this chiller looks like old itelco-clima/york YCAM chiller with some kind of retrofit

I'll try again on 16 September 2013.
I hope we will be.
Thank you friends

Friends, I tried, but unfortunately the problem is not solved.
"OFF BYE MASK" banner removed.
looking at the display "ON" shows.

There are still problems, but the other, which I mentioned.

At this moment you need equipment manual, not controller manual. Where are 3 ways to start equipment: keyboard, DI, BMS.
