OWNER/INSTALLATION MANUAL
3�9 POOL PUMP SYNCHRONISATION
TERMINALS P1 AND P2
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 period of "pump on" has been set on the time
clock for filtration purposes.
b) a period of "pump off" has been set on the time
clock and 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
"pump off" for 5 minutes to circulate the pool
water through the heat pump to sample the water
temperature. The default sampling time interval is 2

hours. If the pool does not need heating/cooling the
filter pump will be turned off after 5 minutes until the
next sampling period, or the next timeclock "pump
on" period. If the pool needs heating/cooling the heat
pump will continue to run the filter pump and heat/
cool the pool.
If 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.
