Introduction Specications and Overview (continued)

6th Sense Technology

Sense software makes an estimation of the actual food temperature inside the refrigerator and freezer compartment and adjusts cooling to allow the food packages to return their initial temperature faster during pull

down, door openings, or heavy food load. 6 Sense algorithm runs in both freezer compartment and refrigerator compartment and each contains 3 routines: Trigger, Package Estimator, and Defrost Manager.

Trigger routine is executed every 2.5 seconds while Package Estimator and Defrost Manager are executed every 10 seconds. The trigger routine is divided into two subroutines: door monitoring and temperature monitoring. Trigger parameters and performance parameters reside in

the User Interface board, the actual 6

sense algorithm resides in Gemini Flash board.

Package Estimator routine computes an estimation of food in FC and RC according to Thermistor reading and door status. Package estimator is run when the User Interface sends the required parameters to Gemini flash and sets the 6th Sense Enable bit to true. If 6 needed, it will call for additional cooling by turning on compressor, damper and evaporator fan.

Sense is

Defrost manager is composed of two main states: Normal and 6th Sense.

When 6

Sense routine is active, defrost will be inhibited based on the control parameters set-

tings to allow food temperature recovery.

WARNING

Refrigerator Thermistor

The refrigerator Thermistor is a variable resistance device connected to the control board.

The temperature of the refrigerator compartment causes the resistance of the Thermistor to

change. The resistance is monitored by a circuit on the control board which controls the operation of the cooling system. The Thermistor is located on the right side of the refrigerator cabinet

attached to the back of the cover labeled 6

sense.
