OWNER/INSTALLATION MANUAL
3�8 POOL PUMP SYNCHRONISATION
TERMINALS P1 AND P2
*The installer will need to adjust parameter P0 when using this feature�
For installations where the pool filter pump runs
continuously, these terminals do not need to be used.
For installations where a timeclock controls the pool
filter pump, and the same pump provides water flow
to the heat pump, the heat pump can override "pump
off" periods to ensure the pool is heated/cooled. To
activate this setting please speak to your installer.
When installed in parallel with the timeclock, the pool
filter pump will run when:
a) a block period of "pump on" has been set on the
time clock for filtration purposes.
b) the heat pump runs the pool filter pump for
temperature sampling and if the pool subsequently
requires heating/cooling.
This feature operates by over-riding the timeclock for
3 minutes to circulate the pool water through the heat
pump to sample the water temperature. The default
sampling time interval is 1 hour.

If the measured temperature is more than 1°C
from the set temperature, the point heat pump will
continue to run the filter pump and heat/cool the pool.
If the measured temperature is within 1°C of the set
temperature, the filter pump will turned off until the
next sampling period, or the next timeclock "pump on"
period.
When the pool pump is already running, and the
heat pump is not heating/cooling, the heat pump will
sample the water temperature once per hour and will
start heating/cooling if needed. The heat pump will
ignore a demand to heat/cool the pool until the
sampling timer (default 1 hour) has elapsed*.
This feature will reduce the pool filter pump run time to
minimise pump energy usage.
*If the pool filter pump is later changed to run
continuously, it is recommended to de-activate this
setting so the heat pump will respond to a heating/
cooling demand without waiting for the sampling time
interval to elapse. To deactivate this setting please
speak to your installer.
