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.
