2.1 Functions of the Manual Control Panel
The air conditioner control panel (one for single loop system and two for dual loop system) has two rotary switches, one for the
blower speed (E) and one for the temperature adjustment (G). It also has an LED indicator (F) to signal activation of the AC
compressor drive clutch.
Figure 2
shows the features of the control panel.

Temperature Adjustment Switch
The Temperature Adjust Switch (G) is used to set the ideal or desired temperature level for the user. This can be varied between
approximately 64°F (18°C) and 78°F (26°C). The system is then automatically regulated and operates until the set value is obtained.
Cooling Compressor LED
The LED indicator (F) lights blue while the AC Compressor Clutch is activated, the condenser fans are running and the cooling
system is active. The LED turns off when the cabin temperature falls to the set level.
The Blower Switch
The blower motors have three modes of operation controlled by the Blower Switch (E)
– Low, Medium and High speed. The blowers
do not run and no cooling occurs at the OFF position (A).
The Low (B) Medium (C) and High (D) switch positions keep the blowers continuously running at low, medium or high fixed speeds
respectively, independent of the set or actual temperature values.
