The Manual Speed setting value will follow the target speed while Capacity Control = Auto. When Capacity Control is set to ManSpd, the Manual
Speed set point can be set to the desired value. The minimum will be the same minimum speed calculated for automatic control. The maximum
value is equal to the Compressor Maximum Speed setting.
The Manual VR setting value will follow the target capacity while VR Control = Auto. When VR Control is set to Manual, the Manual VR set point
can be set to the desired value.

Circuit Test Mode Set Points
Circuit test mode set points can be changed when either the
unit mode is Test, or the circuit mode is Test. When neither the
unit nor the circuit are in Test mode, all the circuit test mode set
points for the circuit are automatically changed back to their
‘off’ values.
