h) Dual Temp Freezer Component Control (S3 dip switch 8)
Dual Temp only. Active when S3 dip switch 1 is in the "OFF" position (freezer application)
and S3 dip switch 6 is in the "ON" position (Dual Temp application).
When S3 dip switch
8 is in the "OFF" position, the component(s) on CB K9 pin #2 circuit energize and
de-energize with the compressor and the evaporator fan motor cycles according to S3
dip switch 7 setting. When S3 dip switch 8 is in the "ON" position, the component(s)
on CB K9 pin #2 circuit energize at the beginning of the first cool down achieved cycle
and the evaporator fan motor runs continuously (except in defrost and door open).
NOTICE!
Do not adjust S3 dip switch 8 out of the factory default position. This dip
switch must be left in the factory default position or the appliance will not operate
correctly.
Factory set, no adjustment required.
Note: S3 dip switch 8 is ignored when S3 dip switch 1 is in the "ON" position or S3 dip
switch 6 is in the "OFF" position.
