allowed to operate. The default setting allows full operation of all outputs over a 24-
hour period (assuming no lockouts are active). Each output (WC, Shower and
basins) can be assigned to a configurable timeslot and when activated the assigned
output will only become active if within the allowed ‘time slot’. This function can be
used to manage when sanitary ware is allowed to operate, for instance the showers
may become inactive during night time periods. See pages 28-29 for Time Slot
setting information.
5.14. Hygiene Purge
The control unit can purge an output following pre-set periods of inactivity, this is a
hygiene function that can be used to reduce the possibility of water stagnating in the
pipe work and the associated risks, it will also reduce the possibility of waste traps
drying / evaporating following periods of inactivity. The inactivity period, duration of
purge and time of day when the purge takes place are all configurable for each
output. See page 27 and 28 for Hygiene Purge setting information.

seconds, after which the WC is ready to flush again.
If the WC is not a cistern type flush, but is flushed directly from the water mains or a
central tank system, the flush time may have been set with a different cycle time to
suit the system flow performance.
•A dual flush option is available, either using one touch button or sensor, or using
two independent buttons or sensors. One of the two buttons or sensors is used to
operate a full flush the other for a half flush. Figure 2 on page 11 gives the
location of the half flush input sockets. Refer to Table 6 on page 23 for
instructions on setting a dual flush using one Piezo touch button or sensor
connected to sockets A and E.
The controller has various function settings that are described in Table 6 on page 23.
A few important settings and their default states are given in Table 5.
