Top Mount : Deluxe models: -------------------

This refrigerator is managed by an Electronic System, mainly consisting of the components:

• Electronic Control Board (Nilgiri- Dlx (BEE))

• POT (Potentiometer) in case of Dlx (BEE) models only.

• Temperature Sensors {refrigerator, Defrost & POT(Dlx)}

• Compressor ( With Run capacitor)

• Freezer Fan Motor (AC)

• Defrost Heater ( Integrated Al tube 245W)

• Door Open Sensing

These components are described as shown below.

– Electronic Control

The complete operation of this product is done by the Electronic Control, Functions of this models are
fully controlled by the Micro-controller IC which executes the functions according to the needs, turning
the components On or Off through received/managed signals, such as:

- Compressor On/Off

- Defrost Heater On/Off

- Temp setting in refrigerator Compartment, through received signals by the POT along with the RC &

FC Sensors Temp. Feedback.

- Door open sensing / Alarm

- Among many other functions controlled by its software.

The Electronic Control is located at the rear of the refrigerator, next to the cabinet and besides the
Compressor, inside a plastic box. Cables going inside the product, using connectors that do not permit an
assembling failure do its connection to the mains and its components.
