The operating mode controlled by the time bands is indicated
by the symbol on the display.
n.B. the on status controlled by the time bands is only
valid if the machine is first activated from the keypad or
the remote input (if enabled).
The OFF status controlled by the time bands, displayed by
the “half moon” symbol on the display, acts according to
whether parameter
rt
is set to 1 or 2:
rt= 1, sleep mode:
during the OFF status, the fan, if controlled
proportionally, works at minimum and the actuators remain
off.

In the event of an alarm the alarm code, hour, minute and data
are recorded, up to a maximum of 300 signals. On reaching
the maximum number the oldest events are deleted (code 1
always indicates the most recent alarm).

buttons scroll the alarm data. In places where no alarm has
been recorded, dashes are displayed in the place of the code.
The display includes an incremental index in the right-hand
field, which identifies the current position; the hundreds then
appear in the field on the left (e.g.: “1 rES 55” indicates that
a reset of the machine was performed, and the position is
155).
The machine is reactivated in the following conditions:
a)
the temperature exceeds 70% of the high/low alarm
threshold,returning to Sleep if the temperature falls within 40%
of the alarm delta.
b)
the ON/OFF is pressed: in this case the on status lasts
until the next time band; during this period the symbol “A”
flashes.
rt= 2:
the machine is in stand-by, as if the ON/OFF had been
pressed. In this case too, pressing the
on/oFF
button activates
the machine until the next band switching OFF time.
