Climate Control System Operation

NOTICE!

If water gets in the control panel or the sunlight 
sensor, a failure may result. Always keep these 
components clear and free of water. Failure to 
follow this notice could damage the machine or 
cause it to operate improperly.

NOTE: 

Check the fuses if there is a problem with the 
climate control panel operation. Check the 
sunlight sensor for blockage or damage if there is 
a problem with the climate control system. 
Contact a SANY dealer for further information.

NOTE: 

A sunlight sensor adjusts the airflow of the climate 

control system when the cab is in direct sunlight. See 
“Sunlight Sensor” on page 3-19.

Automatic Temperature Control (AUTO) 

Press AUTO (6) to activate the automatic temperature 
control system. The climate control panel will 
automatically adjust fan speed, outlet vents, and air 
source to achieve and maintain the selected 
temperature. The desired temperature can be changed 
while in AUTO mode. Any other selection will deactivate 
the automatic temperature control.
