MODE button
(fig.26)
Used to select one of the available operating modes
(MAN, BP, AUTO). Press the key to switch between
modes.
AUTO (fig.26a):
the operating speed is automatically set by the system,
depending on the environmental conditions detected by
the sensors; if necessary the by-pass and frost
protection valves are activated automatically;
Bypass function activation is indicated by the flashing
"BP" icon on the display.
MAN (fig.26b):
the operating speed is decided by the user (the CO2
and relative humidity sensors can still trigger a shift to
Max speed if necessary);
BP (fig.26c):
this forces the opening of the by-pass valve, irrespective
of the actual desired internal, desired or external
temperature values.
The shift from one operating mode to the other is
achieved by pressing the MODE button for at least 0.5
seconds
