6.1.
Operation
Use the main isolation switch provided by the installer to switch the unit on or off.
The main isolation switch is located near to the electronic control box. If unit is faulty,
switch off the control unit until the fault is repaired by a qualified engineer.
WARNING! Risk of electric shock, serious injury and death. Only trained and
qualified personnel should remove the cover of the electronic control box.
The basin, shower and WC are fitted with either Piezo type stainless steel touch
buttons or infrared sensors.
Press the button face to operate a Piezo touch button. Once an operation cycle
starts, it will continue for a fixed period and stop unless the touch button is pressed
again, which will cancel the operation. The shower and WC cycles, however, cannot
be interrupted in this way.
Hold your hand within 50mm of the infrared sensor to operate an infrared sensor.
The operation cannot be interrupted or stopped when infrared sensors are fitted.
•
The hot and cold basin valves are opened for 10 seconds each.
•
The hot, warm and cold shower valves are opened for 60 seconds each.
•
The WC flush valve is opened to deliver a 6 litre flush. The cistern refill time is 30
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.
