Setpoint Screen Index
The available Setpoint Screens for the VCM controller are listed on the
next few pages by sequential screen number. When each VCM control-
ler is configured for the first time, it is best to start with screen #1 and
proceed to each Setpoint Screen in numerical order until you have
viewed all available Setpoint Screens. This ensures that you have seen
all the available VCM controller Setpoint possibilities and have the
opportunity to change or accept the defaults for each screen. Once the
unit Setpoints are configured and you decide to change one of the screen
options it is helpful to know what screen number contains the configu-
ration you wish to change. With this in mind, following is a list of all
the VCM Setpoint Screens in numerical order with a brief listing of the
Setpoint feature available on each screen.
