SYNCHRONISATION OF DEFROSTING PERI-
ODS (ONLY IF PARAMETER i0 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 with
parameter d24 or until the conclusion of 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 conclu-
sion of the predripping of the last device to end the same.
