Zone Link

When enabled, the Zone Link feature links the fan temperature and speed values for both the left and right climate zones.

The left climate zone takes priority when enabling this feature, that is, the right zone will have its fan temperature and speed set to that of the left. Disabling Zone Link will once again allow both zones to be managed independently.

Examples

Set the left-zone temperature to 20 oC:

echo temperature_row1left:n:20 >> /pps/qnxcar/hvac

Set the right-zone fan speed to 4:

echo fanSpeed_row1right:n:4 >> /pps/qnxcar/hvac

Turn rear defrost off:

echo defrost_all:b:false >> /pps/qnxcar/hvac
