Piezo pushbutton and infra red sensor controls
Piezo pushbuttons and infra red sensors can be connected to the control unit to operate the
basins, showers and WCs. You can connect either Piezo pushbuttons or infra red sensors to
the control unit.
The control unit is set for use with Piezo pushbuttons by default.
If you connect infra red sensors to the control unit, you must modify the applicable setting.
For instructions on how to do this, refer to Table 5 on page 32. You do not have to modify
this setting if the control unit is factory set for operation with infra red sensors.
The Piezo pushbuttons do not have any moving parts.
To operate the Piezo pushbutton:
1.
Press the centre of the button to start the operation.
2.
Press the centre of the button to stop the operation (basin hot and cold only).
To operate the infra red sensor:
1.
Hold your hand within 50mm of the infrared sensor.
NOTE: Infra red sensors cannot stop or interrupt an operation until the operation is
complete. Piezo pushbuttons can interrupt or stop an operation. For example, you
can interrupt a basin operation by pressing the piezo button again. You cannot
interrupt a basin operation by operating the infra red sensor again.
To test the operation of the piezo and infrared sensors:
1.
Operate each pushbutton or sensor and observe that they work correctly.
The hot and cold basin valves are set to open for 10 seconds each.
The shower valves are set to open for 60 seconds each.
The WC flush valve is set to open for 3.3 seconds (6 litre flush). The cistern refill time
is 30 seconds, after which the WC is ready to flush again. The WC control can be set
for dual flush, refer to section 6.1 for instructions.
