th
Sense Technology
6
th
Sense software makes an estimation of
the actual food temperature inside the refrig-
erator 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
th
Sense algorithm runs in both freezer com-
partment 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 moni-
toring and temperature monitoring. Trigger parameters and performance parameters reside in
the User Interface board, the actual 6
th
sense algorithm resides in Gemini Flash board.
Package Estimator routine computes an estimation of food in FC and RC according to Therm-
istor 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
th
Sense is
needed, it will call for additional cooling by turning on compressor, damper and evaporator fan.
Defrost manager is composed of two main states: Normal and 6th Sense.
When 6
th
Sense routine is active, defrost will be inhibited based on the control parameters set-
tings to allow food temperature recovery.
