Any setting not mentioned in this guide is generally not required to setup the system and should be left as default.
Allow 30-45 minutes to program and check each unit.
If no button is pressed the system will time out and you will have to re-enter the menu. •
If the unit has been previously setup or ‘fiddled with’ we would advise starting with a factory reset. This can be
found at the bottom of the engineering menu
The first 7 steps are all to be found in the Guard menu and are mostly in logical order as you go down through the menu.
STEP 1 Set time and date – Locate and set the unit to the correct time and date. [exit menu to home screen by pressing
R/H arrow, check time and date is displaying correctly. It is important to do this first as it affects further settings options]
STEP 2 HI GRD LTR – Press ok and set hi grd value. Min is 1ltr, Max is 2000ltr. This is the lower value of the two for when
the building is not expected to use as much water . [Use left and right arrows to enter higher values faster. We selected
50] Press ok to exit back to menu. [if you skipped step 1 and the building is in use, expect the unit to go into alarm now].
STEP 3 LO GRD LTR – Press ok and set lo grd value. Min is 1ltr, Max 5000000ltr. This is the higher value of the two for
when the building is expected to use the most water. [Use left and right arrows to enter higher values faster. We select-
ed 100] Press ok to exit back to menu.
STEP 4 Override time – press ok to cycle to 45. The override function allows you to use unlimited water for the period
entered without the unit going into alarm. Once started a countdown will begin once the period ends the system will
automatically revert to its normal settings.
STEP 5 Meter 1 (2) –- Press ok and set to match the reading from the top of water meter 1. [Use left and right arrows to
enter higher values faster.] Press ok to exit back to menu and repeat for meter 2 if two meters are fitted.
Skip time and date as we have already done these.
STEP 6 Mode – Press ok to cycle through options available [the different modes are described on page 6 of this manual.
For this example we will assume daily has been selected]
STEP 7 Set HI/LO Times – Press ok to enter the set Low Guard time period screen. This is the time the building is occu-
pied. Set lines 1 and 2 the same [if you do not the system will go into alarm]. All times out of this period are high guard.
[A value MUST be entered in this screen. If you require a value higher than 2000ltr per half hour, in effect a permanent
low guard, then we would advise setting this low period to 1 minute at midnight ie. 00.01 – 00.00. For our example we
have entered 06.00 – 18.00]. Press ok and left arrow once to exit to menu.
This is the end of the guard menu the next steps are in the engineering menu, again in order.
