The display board, once installed, is used to perform all the confi guration
and programming operations on the driver. It displays the operating status,
the signifi cant values for the type of control that the driver is performing
(e.g. superheat control), the alarms, the status of the digital inputs and
the relay output. Finally, it can save the confi guration parameters for one
driver and transfer them to a second driver (see the procedure for upload
and download parameters).
For installation:

buttons that, pressed alone or in combination, are used to perform all the
confi guration and programming operations on the driver.
