POWER
INTERRUPTED
The cumulative number of power interruptions (i.e. controller turned o/power cut).
This is a cumulative counter, the value of which cannot be modified. If using the
engineer’s code, the counter can be reset to zero by holding the (MUTE) buon.
-
12 PULSE
When enabled, if a pump has been inactive for 60 days, it will start and run for
2 seconds. This is to prevent the pumps from seizing.
YES
13
EXCESSIVE
START
When enabled, if there are more than 3 individual pump runs within an 8 hour
period, the unit will register an <EXCESSIVE DEMAND> alarm. Enabling this option
may cause false alarms on some systems.
NO
14 SERVICE
When enabled, a service reminder will be displayed aer 12 months from when the
option was enabled.
To reset the service reminder, set the value to ‘NO’ and exit the menu. Then, re-enter
the menu and set the value to ‘YES’ again.
NO
15 FILL SYSTEM
When enabled, the <LOW PRESSURE> and <FLOOD LIMIT> alarms will be disabled,
and pump 1 will run continuously for up to 24 hours until the cold fill pressure has
been reached.
Once the cold fill pressure has been reached, this option will automatically be
deactivated, and the low pressure alarm and flood limit will be reactivated. This
function is used to fill a system that is empty or at low pressure.
Care must be taken using this option as the flood limit alarm is disabled, increasing
the risk of flooding.
This option cannot be enabled on Mini pressurisation units.
NO
If using the customer code, the menu will end at this point. Aer pressing (SET) once more, the controller will
display “SAVING...” and return to normal operating mode. If using the engineer’s code, additional menu items
will be displayed.
The following seings are all pre-programmed in the factory and should not need to be modified on site. If
these seings appear to have been reset, the most likely cause is a power spike. If this problem persists, a
power filter may be required.
The following seings are for experienced engineers only. Incorrect configuration of these seings can cause
the equipment not to function correctly, and may cause damage to the equipment, system or property.

18 PUMP SENSE Disabling this option will stop the controller from monitoring the pumps and
generating <PUMP FAIL> faults.
It is not recommended to disable this option.
