2 Operation
The operating panel of the MC3-SC is split into two parts, with the compressor part (SUCTION) on
the left and the condenser part (DISCHARGE) on the right. These two parts are operated and read in
virtually the same way. The current status and settings of the controller can be read off from the
touch panel.
2.1 General
This manual gives an abridged overview of the options for operating the NC3-SC controller. This
document describes how to operate the controller via the touch screen. The various possibilities
are explained using screen shots. The screen shorts were made with the controller language set to
English.
2.2 Standby mode
When the power to the controller is switched on, it will start up and display the following screen.
This screen shows that the controller is in standby mode. Various actions can be taken from here:
-
Reinitialize the communication between the controller and the touchscreen.
This is possible if the touchscreen has been switched on before the controller. In such
cases, it is possible that the touchscreen cannot see whether the controller has come out
of standby mode. This action is taken by pressing the VDH logo.
-
Switching the controller off
Pressing the “Power off” button switches of the controller completely. This should be done
before disconnecting it from the mains, e.g. for maintenance. It is possible to disconnect
the controller without using this button first, but this can have a negative effect in the
longer term on the lifespan of the SD card in the controller. Confirmation is requested
before the controller is actually switched off.
