3.1 Assembling the display board (accessory)
The display board, once installed, is used to perform all the conguration and
programming operations on the two drivers. It displays the operating status,
the signicant values for the type of control that the drivers are performing
(e.g. superheat control), the alarms, the status of the digital inputs and the
relay outputs. Finally, it can save the conguration parameters for one
controller and transfer them to a second controller (see the procedure for
uploading and downloading the parameters).
For installation:
• remove the cover, pressing on the fastening points;
• t the display board, as shown;
• the display will come on, and if the controller is being commissioned, the
guided conguration procedure will start.

Important: the controller is not activated if the conguration
procedure has not been completed.
The front panel now holds the display and the keypad, made up of 6 buttons,
that, pressed alone or in combination, are used to perform all the conguration
and programming operations on the controller.
3.2 Display and keypad
The graphic display shows two variables for each driver (A, B), the control
status of the driver, activation of the protectors, any alarms and the status of
the relay output.
