(*) The display shows a table where the columns represent the 2 capacity
modulation steps and the rows contain the following information:
Row F - the symbol “

“-” is shown
Row D - the symbol “

” appears if the branch is draining (valve open),
otherwise “-” is displayed if the drain valve is closed.
In column Hr, if the heat recovery is active, the symbol “ “, otherwise “ “.
In column Pr, the priority choice will be shown: the symbol “ “ if priority is

8.9 “Warnings” screen
The warning screen spontaneously displays messages generated by fixed

optiMist resumes operation: the reset alarm message will appear on the
warning screen.
