The DSE 7320 MK 2 controller, as well as the DSE 7310 MK 2 have the option of a backlight power saving mode. This is disabled by default.
When enabled, the display on the DSE controller will become dimmed while in standby mode.
To enable this power saving mode, configure as follows:
First, enable the setting "Enable Backlight Power Saving Mode".
Then make sure in timers, the backlight power saving is set to the time you require. The default is 5mins.
After this the DSE module, when in standby mode will save power by turning off the backlight after the specified period of time.
