For installations where e pool filter pump runs
continuously, ese terminals do not need to be used.
For installations where a timeclock controls e pool
filter pump, and e same pump provides water flow
to e heat pump, e heat pump can override “pump
off” periods to ensure e pool is heated/cooled. To
activate is setting please speak to your installer.
When installed in parallel wi e timeclock, e pool
filter pump will run when:
a) a block period of “pump on” has been set on e
time clock for filtration purposes.
b) e heat pump runs e pool filter pump for
temperature sampling and if e pool subsequently
requires heating/cooling.
This feature operates by over-riding e timeclock
for 3 minutes to circulate e pool water rough
e heat pump to sample e water temperature.
The default sampling time interval is 1 hour. If e
measured temperature is more an 1°C from e set
temperature, e point heat pump will continue to run
e filter pump and heat/cool e pool. If e measured
temperature is wiin 1°C of e set temperature,
e filter pump will turned off until e next sampling
period, or e next timeclock “pump on” period.
When e pool pump is already running, and e
heat pump is not heating/cooling, e heat pump will
sample e water temperature once per hour and will
start heating/cooling if needed. The heat pump will
ignore a demand to heat/cool e pool until e
sampling timer (default 1 hour) has elapsed*.
This feature will reduce e pool filter pump run time to
minimise pump energy usage.
*If e pool filter pump is later changed to run
continuously, it is recommended to de-activate is
setting so e heat pump will respond to a heating/
cooling demand wiout waiting for e sampling time
interval to elapse. To deactivate is setting please
speak to your installer.
