REMARKS
1. Fan voltage of each control mode
2. Control against (under) load (Load Control)
1) Purpose : To restore F/R-temperature which has risen by load (much foods in or
frequent door openings) as soon as possible
2) Display : "SPEED" lights until the mode and speed icons flicker.
3) Conditions to start (from both Normal and Silence)
F or R door open time exceeds 30 secon d
s at a time Freezer and Refrigerator
load control starts respectively .
Over [F-sensor On Point + 5 degree]
F load control
Over [R-sensor On Point + 5 degree]
R load control
4) Conditions to avoid load control
Initial operation (right after power input, Just after Pre-cool, Heater defrosting,
Pause, Defrosting cycle.)
(After door opening, the load control enters if the condition complies with.)
(During Sleep Mode1, load control isn t active.)
5) Control Method
5-1) Control mode by F/R-door open time (over 30 seconds)
F/R-fan works by 14V respectively.
5-2) Control mode by [F-sensor On Point + 5 degree]
F-fan works by 14V.
5-3) Control mode by [R-sensor On Point + 5 degree]
R-fan works by 14V.
C-fan works by 10V as normal.
6) Conditions to stop
The mode works for 20 minutes.
(If another condition happens at the end of the mode, it starts again.)
