Figure 6-2: Drain group consisting of drain tank A and disinfected tank 1
Drain groups are usually set once, see "Drain groups / Drain group characteristics" on
page80.
More information on how to set the other start conditions and periods for each drain
group can be found in section "Drain group settings" on page73.
The start and stop conditions can be set for four different periods. The periods can be
set in absolute time or as times in relation to sunrise or sunset. "Period" on page76.
6.3.1 Warming up UV lamps
Warming up the UV lamps allows the radiation level of the lamps to reach the desired
intensity, before the disinfection process actually starts. The warm-up phase also
enables the blending ratio between fresh water and drain water to stabilize. During
this phase, the water is either fed back into the drain tank or discharged from the
system as wastewater. The warm-up duration, the blending ratio and the destination
of the water during the warm-up phase can be preset.

The current system status can be viewed on the display of the unit or in the Synopta
software on your PC. See also: "Warming up UV lamps" on page73.
