OWNER/INSTALLATION MANUAL
4�3 POOL PUMP SYNCHRONISATION
For installations where a time clock controls the filter
pump, which also provides water for the heat pump,
your heat pump can over-ride "pump off " periods.
By doing so, your filter pump will only run when
a) a block period of pump "running" has been set on
the time clock for filtration purposes.
b) the pool requires heating
This feature operated by over-riding the time clock for
five minutes each hour. This allows pool water to be
circulated through the heat pump

During this sampling period if the heat pump detects a
need for water heating, it will continue to over-ride the
time clock until the pool water temperature is satisfied.
If water heating is not required, the over-ride will stop,
and the filter pump will turn off, and not restart until the
next hourly sampling period, or pre-set run time.
This feature will reduce the filter pump run time, and
consequently save energy as well as unnecessary filter
pump wear and tear.
