X: 0 = no sensor
1 = sensor 1
2 = sensor 1 high, sensor 2 low, crossover fade
7 = sensor 1 high, sensor 2 low, crossover target pressure
9 = sensor 1 high, sensor 2 low, crossover switch point
3 = sensor 2
4 = sensor 2 high, sensor 1 low, crossover fade
8 = sensor 2 high, sensor 1 low, crossover target pressure
10 = sensor 2 high, sensor 1 low, crossover switch point
2 sensor operation are possible with 2 sensor hardware [950..-...Q -....] only.
For applications where the high range sensor is used for monitoring purpose
only, select sensor operation modes 1 or 3 for pressure control with low range
sensor and read high range sensor from SENSOR 1 READING resp. SENSOR
2 READING.
