Function Ice Maker Ice Maker Ice cubes are dropped into the bucket when the tray is twisted. 12V DC motor. 5V DC supply to internal control circuit. The ice maker is supplied with water from the domestic mains supply which is first filtered then passes via two solenoid valves connected hydraulically in series and supplied electrically in parallel to ensure a high standard of safety in operation. On reaching a temperature of -10 C, a probe at the bottom of the tray sends a signal to the Ice Maker motor which rotates and twists the tray and the ice cubes fall into the bucket below. This cycle is repeated until the bucket is full of ice which pushes up the lever of a sensor which cuts off electricity to the ice maker. When the container is emptied, the cycle starts again. To make medium-size cubes the magnet valve must be powered for 5 seconds, which fills approximately 80cc of water. To make largesize cubes the magnet valve must be powered for 7 seconds, which fills approximately 110cc of water. An average quantity of 1kg = 100 large cubes is produced within 24 hours. If no ice has been made, check if the TriMode compartment has been set to freezer and that the Ice Maker button has been pressed. Check also that the appliance is connected correctly to the mains water supply and that the valve is open, check the magnet valve is working properly, do a manual wash (via menu) to take sure water is getting to the ice maker.

Function Description of circuit Defrosting Refrigeration and Cool compartment Defrosting takes place naturally every time the compressors stops (the fan to circulate air inside stays on at low speed). The compressor is restarted when the evaporator probe temperature reaches +3 C. In addition, every 24 hours a safety defrost is run and the compressors is only restarted when the evaporator probe reaches +7 C. The defrost water is carried to two evaporation trays placed at the head of the compressors (bottom compressors appliances). Freezer part TriMode The TriMode compartment comes out of the factory as a freezer but users can easily configure it as a fridge or low temperature compartment or when wines are stored, as a wine cooler. The TriMode circuit is completely separate from the refrigeration / wine cooler circuit and is managed by a specific compressors.

Function Description of circuit Freezer part TriMode The evaporator is controlled by 2 temperature probes, one in the air beside the evaporator to check the temperature in the compartment, and one in contact with the evaporator to control the defrost temperature. Cool air is distributed in the TriMode compartment by an brushless 12V DC fan as follows: Chilling stage: fan switched on 1 minute after the compressor starts and switched off when the compressor stops. Defrosting stage: fan always off. Fast freezing stage: fan always switched on (compressors always on for up to 54 hours). A temperature probe in contact with ice condenser constantly monitors the temperature in order to manage the fan. The condenser fan starts when a temperature of 36 C is read, and stops when a temperature of 33 C is reached, or 300 seconds after the last compressor, whichever one, never has priority over other with regards to switching off the fan. Defrosting TriMode compartment Defrosting is forced by a heating element placed in contact with the evaporator. The fan stays off during this stage. The defrost water is carried to two evaporation trays placed at the head of the compressors (bottom compressors appliances).

Function Description of circuit Minimum and maximum compressor OFF / ON times Minimum OFF time: 5 minutes for the fridge and 10 minutes for the freezer. To avoid the compressor switch ON before the pressure has balanced. Maximum OFF time: 360 minutes for both, fridge and the freezer. To prevent expended pauses at low ambient temperatures. Minimum ON time: 10 minutes for both the fridge and for the freezer. Maximum ON time: 720 minutes. To prevent extended running times at very high ambient temperatures (except during the Shopping function - for freezing).
