PR053SPEED REQUESTED BY HEATING/AIR CONDITIONING
PARAMETER
DEFINITIONThis parameter indicates the engine's speed of rotation with air conditioning in rpm.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
Note:
Take parameter PR053 into account only if PR037 Refrigerant pressure > 12 bar.
Conformity check: Engine stopped and ignition on
The value of the engine speed with air conditioning must be:
PR053 = 0 rpm (ignition on).
Conformity check with the engine running and engine coolant temperature > 80°C
The speed requested by the air-conditioning is increased and varies around 850 rpm.
