Automatic Temperature Control (Atc) - New Holland T7030 Operator's Manual

SECTION 2 - - CONTROLS, INSTRUMENTS AND OPERATION

Automatic Temperature Control (ATC)

(where fitted)
Automatic Control
With Automatic Temperature Control the operator
can set the temperature inside the cab to maintain a
comfortable working environment. By automatically
adjusting the output of the heating and air
conditioning systems, ATC will provide a stable cab
temperature between 16° C (61° F) and 32° C (90°
F).
The blower control switch (1) has five positions, off,
ATC and three blower speeds. With ATC selected
the speed of the blower fan is controlled
automatically.
To set the cab interior temperature, align the mark on
21
the control knob (2) with the desired figure. If
required, the control can be set to the intermediate
positions between the figures to provide additional
temperature levels.
If the temperature in the cab remains within 1.1° C (2°
F) of that set on the control, the blower fan will
maintain a low speed. As the differential between the
control setting and the in cab temperature increases,
the blower speed will be raised to re--stabilise the
temperature.
Selecting 'HI' or 'LO' on the temperature control will
override the automatic system to provide a maximum
heating or cooling effect.
Manual Control
To manually set the cab temperature, switch the
blower control to position I, II or III and select a
suitable setting on the temperature control. This will
disable the ATC function.
Although the in cab temperature will be maintained
within limits, it will not be as efficient as ATC.
Switching to 'LO' will provide maximum air
conditioning output with temperature adjustment
through the blower control only.
