REVO-E Heat pump
4 Function and functional schematics
4.4.4 Cooling Mode
Requirements:
–
Terminal 15 active
–
Vehicle hybrid system active
–
Mode “Ready for Cooling“ active
–
HVAC power consumption enabled by
“D_AuxiliaryPowerEnabled” signal
–
Signal “D_CabinCoolReq” sent by BEA-Body
–
environmental temperature > 5°C
The Cooling Mode is requested by the BEA body system
in order to cool down the air in the passenger cabin. The
SC620 therefore assumes internal control of the compo-
nents in the system in order to cool down the air in the
passenger cabin to the Delta T value requested by the
BEA Body.
