c. Individual circulation pump installation.
An onboard output initiates the circulation pump to start and stop from the heat pump itself
based on temperature and timers. For use when there are dedicated heating pipes and to
separate from the filtration timers.
1- Termination points are labelled P1-P2 from the on board relay and is activated by the timers and
pool temperature, and will continue to run the pump until the heated water reaches the set
temperature or the timer switches off.
2- Once temperature is reached or the timer is finished the heat pump will switch off the relay output
stopping the circulation pump.
3- If the pool reaches temperature but the timer is still active the heat pump will switch off relay to stop
the circulation pump. Whilst the timer is still active every hour it will run the circulation pump for 2
minutes to test the water temperature. If the temperature is 1 degree below set point the heat pump
will continue to run the circulation pump and start the heating process again.
4- P1 – P2 relay up to 10A output for circulation pump (check total load on circuit when combined)
(P1 and P2 is an output relay switch not active neutral terminals, please see wiring diagram for
further information.
5- Heat Pump timers are set through the mobile application and required a WiFi connection. If no WiFi
is present then additional external timer may be required (sold separately)
6- It is recommended to install a power point for the pump to plug into for any future service work to
the pump which may be required.
7- Circulation pump should be sized accordingly to suit the site conditions and flow required.
