Contactor - ONLY CB1565
H.P. Pressure switch - Only CB1565
The ice maker is energized by the bin thermostat, that stops
machine when the bin is full.
The timer is designed in such a way that it is connected
upstream the bin thermostat during the ice production phase, so
that the ice maker will stop only when the ice production phase
is over.
The following scheme shows this working system:
Timer
Utilizer
Unit
Bin thermostat
Only in the ice
production phase
NB: some components of the electrical circuit (called Utilizer
Units) are always energized and do not depend on the timer
status. See the following table:
