8 SYNCHRONISATION OF DEFROSTING PERI-
ODS (ONLY IF PARAMETER i0 AND/OR PA-
RAMETER i5 IS SET AT 6)
8.1 Preliminary notes
The activation of defrosting causes the activation of
the digital input (at maximum for the time established
w i t h p a r a m e t e r d 2 4 o r u n t i l t h e c o n c l u s i o n o f
predripping).
If the digital input is connected in parallel to the digital input
of other devices configured in the same way, the activation
of the input caused the activation of defrosting in the other
devices.
The devices start dripping simultaneously with the con-
clusion of the predripping of the last device to end the
same.
