Notes on conguring the controller
Time delay
• ”Delay” determines the time the coolant valve remains open after
the process has been stopped. Determines also the time the pump
(only with an in-line valve) remains running after the process has been
stopped.
Notes on selecting the factory-set basic mode
The controller VNC 2 can be adapted optimally to the spe-
cic application by choosing the appropriate factory-set
mode depending on the components, the application and
the process.
