Compressor Control with
Vission20/20™ Micro-controller (No
Slide Operation)
The Vission20/20™ panel can provide control for
a single screw compressor without slides as long as
Analog Output Board #10 is present and selected in the
Conguration screen, see FIgure 4-11.
The “No Slide“ operation will become active once the
correct type of compressor and model has been chosen,
see Figure 4-12.
The user must select either VSG/VSH or VSM from the
Compressor combo box in page 2 of the Conguration
Menu, and then the Model from the next box.
The choice of this type of compressor will cause the re-
frigerant combo box to be grayed out.
Once the compressor has been selected, the Vission
20/20™ panel touchscreen will show an indicator of VFD
speed percentage, and buttons to increase and decrease
it.
For more information on VFD capacity control, please
check the Vission20/20™ manual (35391SC).
WARNING
Software programming credentials shall only be
made available by the supplier. The user will only
have access to operational features established by the

or death.
