Auxilary Functions
1.11a LED Display:
When not in programming mode the display
shows '- -'
Water flowing through the flow sensor is
indicated by alternately flashing 'flow rate'
for flow sensor 1 and 'flow rate' for flow
sensor 2. When no water is flowing the
display flashes '- -'. Flow rate is displayed
in 0.1 litre increments up to 10 ltrs and then
in 1 ltr increments.
1.11b Flow Rate Display:
When the system is not in status display
mode or configuration mode, it will display
the flow rate on the 7 segment LEDs
With no water flowing the system will
display '- -' momentarily every few
seconds
With water flowing the system will display
the following:
Sensor 1 flow rate, Sensor 2 flow rate,
Combined flow rate ... repeating
Flow rates up to 9.9 ltrs/min will be
displayed to 1 decimal place.
Flow rates of 10 ltrs/min and above will
display the rate as the nearest whole
number.
For example:
3.4 ltrs/min on inlet 1
LED show "3.4"
7.5 ltrs/min on inlet 2
LED shows "7.5"
Then total flow is displayed
LED shows "11"
1.11c Solenoid Switch:
See diagrams 1.13 and 1.14.
Aux 1 is for connection to a momentary
contact switch. When the user closes the
switch Solenoid 1 and Solenoid 2 are
energized for 30 minutes. This allows water
to flow through the shower. If the switch is
closed again the 30 minute timer starts
again.

1.11d Pump Run Switch:
See diagrams 1.13 and 1.14.
Aux 2 is for connection to a momentary
