Real Time Clock (RTC)
The time and date can be set either via the relay fascia using appropriate commands in the SYSTEM CONFIG
menu or using the Reydisp Evolution software. When the relay is de-energized, the battery maintains the time
and date. If battery is low or not available in the relay, then relay does not sync the time and date.
