9. The Radio Communications System - Operation and Troubleshooting
The system uses a coded Radio Signal to communicate and create a wireless link between the Control Panel and the
Control Box. Once linked together, they only communicate every ten minutes, except if the water has been turned off,
then they communicate every 15 or 30 seconds. So if you issue a command by changing a setting, that command will
only take effect at the next ten minute update between the two devices.
During installation, if you have trouble linking the Control Panel to the Control Box as described in Section 4 Step 1. or,
if the Control Panel loses the link with the Control Box after installation at some point, you can link the two devices by
using one of the following two methods:-
A. Manual Radio Link Procedure
The Control Box must be tripped to put it into Search mode, so it will be looking for the Control Panel signal. Trip the
valve by holding down the blue button on the Control Box for three seconds (until the LED lights RED). Once you hear
the valve shut, press the RESET WATER button on the Control Panel. The Panel may initially not respond, but will enter
search mode. Within about two minutes, it will have located the Control Box and the radio link will be established.
B. Automatic Radio Link Procedure Option
If the Control Panel and Control are in range of each other, they will automatically link up after about 90 minutes.
If the Control Panel loses the radio link with the Control Box
The Control Panel will begin to scan and search for the Control Box signal. This will show up as Link Searching on the
display. After a few hours of trying the display will change to Link BAD with a number to denote the number of times
the Panel has tried to relink with the Valve. At 100 attempts it will stop counting, but continue searching for the
Control Box. This will continue until the Control Box is found. This searching will run down the battery more quickly.
So if you notice the display says - Link BAD - follow one of the procedures below.
To fix this, you must first try to re-establish the radio link. There are three optional ways to do this:-
•
You can either follow Step 2 in Section 3, Pg.4 OR
•
Complete the Manual Link Procedure listed earlier in this section, OR
•
Place the Control Panel near to the Control Box, and let the Automatic Radio Link Procedure take place.
Once you have re-established the Radio Link, perform a Radio Range Test to find the strongest signal location. Refer to
Section 8, page 9 or Section 11c, Pg. 20 in this manual for instructions on how to conduct a Radio Range Test. A signal
strength above 50% is best for reliable operation.
If necessary, it is possible to add one or more 6m extensions to extend the cable connecting the Control Box to the
Flow Sensor. This allows you to relocate the Control Box to a position where it can better receive and send signals to
and from the Control Panel.
NOTE: If you cannot re-establish the radio link, there may be a problem with the radio in either the Control Panel
or Control Box, so both will need to be serviced or replaced.
Replacing the batteries
At some point, the system will require its batteries to be replaced. You will be prompted to do this by the Control
Panel, however we recommend you do it every 12 months as a safety precaution in any event. After the new batteries
are installed, the Control Panel and Control Box will link up automatically again within 90 minutes. Do not forget to set
the clock again after you have replaced the Control Panel batteries.
WARNING: Once again, it is absolutely imperative that you clip the lid shut PROPERLY on your Control Box.
Failure to do this will likely cause water damage. Make SURE you slide the PCB into the
grooves on the inside of the box, as if forced, it is possible to close the lid with the PCB not
properly in the grooves. This will allow water in!!!
