Air conditioning control
Different air conditioning control situations are described in the following.
Starting
When you start the tractor, the air conditioning automatically defaults to the last
selected adjustment, apart from the defrosting.
Temporary start mode
When you start the tractor in freezing weather, the air conditioning stays in the
starting mode until the temperature of the engine coolant reaches the preset value.
During the starting mode:
•
The fan speed is at the minimum.
•
The fresh air intake is on.
The starting mode ends when the engine coolant has reached the preset value or
if:
•
The defrosting is connected.
•
The LO setting mode is connected.
•
A different speed is selected for the fan manually.
Priority of functions
The function with a higher priority controls the operations. The priority order of the
functions is as follows.
Defrosting
High priority
OFF mode
.
Compressor, recirculation, fan speed
.
HI setting mode, LO setting mode
Low priority
For example, if you have selected the OFF mode with the fan control knob, the
defrosting function cancels the OFF mode and activates the defrosting functions.
IMPORTANT: Use the air conditioning regularly to prevent seizing of the
compressor.
NOTE: Use the air conditioning for a few minutes at least once a month.
You can activate the air conditioning using the air conditioning system on/off
button also in cold weather.
