There are two submodes within the refrigeration mode that can be activated to achieve
energy conservation

0 - the fan mode is disabled and the evaporator will turn on/off with the activation of
the compressor
1 - (Fan Mode 1) the evaporator fan will turn off 5 minutes after the compressor fan is
turned off
The second submode, , refers to the Periodic Defrost mode. If X =
0 - the periodic defrost mode is disabled

button two while any of the settings are displayed will enter you in to the refrigeration control
