Filling the system
If the sprinkler system was not filled upon initial power up in step 4.1, please proceed to
filling the system, this may activate the alarm output therefore it may be required to
temporarily isolate the alarm. Once system pressure (Pmax) has been made the
controller will start a 1
minute countdown indicating ‘Jockey Mode’ press the ‘Stop’
button and the home screen and green power led should be visible
. If the ‘Spr
A
ctivated’
is displayed press the ‘Reset’
button to reset.

Setting of Pressure Switches (if required)
The pressure switches are pre-set from the factory to suit the associated pump but it
may be required by the installer to adjust the pressure switches from factory set
pressure, it is recommended that the system pressure switches be set at least 1 bar
below system ‘Pmax’ and no less than the
pressure required from the
‘
most
unfavourable hydraulic
calculations’
, it is recommended that the pressure switches are
set within 0.3 bar of each other. Refer to pressure switch instruction manual for setting
instructions, this should be undertaken with the Aquaguard pump controller switched
off.

Flow Test
From the pump test valve, a flow test should be undertaken to check pump satisfies the
flow and pressure requirements set out in the system Hydraulic Calculations, after 20
seconds of the system flowing the ‘Spr Activated’ will appear triggering the alarm output.
Once flow test has
been completed and system repressurised press the ‘Stop’
button
then ‘Reset’
button to return to home screen.

Weekly Test
To manually initiate a weekly test to ensure correct operation of solenoid etc, press and
hold the black button on the bottom of the controller for at least 10 seconds, this will
initiate the weekly test to start, opening the solenoid valve until both pressure switches
are activated and run the pump for 60 seconds checking voltage/current and power are
within set parameters.
If either of the pressure switches are not detected, then a fault will be displayed
indicating either ‘PS1 not detected’ or ‘PS2 not detected’.
