Note:
if the controller is OFF, the light output is controlled only by
the light button. If the controller is ON, the light is controlled by
door light button or light button only, according to the setting
of parameter A4.
Door light button
If A4 = 1, the light is switched on/off only by the light button. The door
status, open or closed, is ignored. If A4 = 0, when the cold room door
is open, the light is always on. When the door is closed, the light can
be switched on or off using the light button. Once on, the light will
automatically switch off after the time set for Li.

7.3 Ultra EVD EVO module commissioning
EVD EVO driver confi guration from UltraCella
Connect UltraCella to the EVD module via serial, as shown in the wiring
diagram in Figure 7.c, and refer to the following parameter table for
confi guration of the EVD EVO driver. The module will become active
when enabled by UltraCella, setting P1 = 1.
If connected via serial, the driver parameters can be displayed only (not
modifi ed) by the local EVD EVO display. Once the driver has been enabled
(parameter P1=1), its parameter settings will be sent by UltraCella, in
accordance with the parameter table below (only modifi able from
UltraCella); any parameters previously confi gured on the EVD EVO display
will be overwritten.
