Functional characteristics
Ice-maker
Ice-Maker ON / OFF manager (IDI Sankyo):
The Ice-Maker system works by itself, it means that the Main Board will just switch ON the relay K002 (for IDI
only) to give the system the power according to the customer user request, moreover the Main Board will detect
the Ice valve activation in order to update the Water Filter Indication counter.
To avoid water overflow, due for example to Ice-Maker wrong functioning, the Main Board will switch OFF
the relay K002 if the ice valve feedback lasts more than 20 seconds.
The Ice-maker system will be switched OFF till the following points will be satisfied:
1) the power has been removed (Power-OFF)
2) the main power has been re-applied (Power-UP)
During this failure condition the Main Board will send the alarm code to the User Interface
