Automatic Temperature Control Operation
1. Press the top of the switch (A) to activate the
automatic mode. An "A" symbol (E) will appear
in the digital display to indicate automatic
operation is on.
2. Set the desired cab temperature using the
Temperature Control (3), the temperature
setting on the display (C) will increase or
decrease accordingly.
NOTE: If the temperature is set to either
maximum or minimum the "A" symbol (E) will
disappear from the display. Turn the
Temperature Control knob slightly away from
maximum/minimum to return to automatic
mode.
NOTE: The temperature display can be set to
read the temperature in either degrees
centigrade or fahrenheit. This is however not an
operator function, for more information see your
dealer.
The blower fan speed will automatically regulate
to achieve and maintain the desired cab temper-
ature.
NOTE: In cold climates the blower speed will
not increase until the heater core is warm. This
will prevent cold air being blown on the
operator.
3. To override the automatic function simply make
a manual adjustment to either the blower speed
(4) or recirculation control (5). The "A" symbol
(E) will disappear, automatic mode disabled.
To return back to the automatic mode, press the
Automatic Temperature Switch (A) to the OFF
position (switch in the centre) and then back to
ON (press top of switch).

Defrost Mode. The Defrost Indicator (D) will
illuminate on the display.

Temperature Control (3).
3. The system will operate the same as in
automatic mode to maximise defrost
capabilities.

If the system fails to function correctly the service
indicator (F) will illuminate and an error code will be
displayed in the Temperature Setting Display (C).
