b. Heat pump activation without using the chlorinator controller and using the one
pump used for filtration (additional controller required)
An on-board pump output relay can activate the main filtration pump by using it in combination with a “single pump
controller” without using the chlorinator timers needing to be activated which will stop over chlorination but still use a single
supply pipework for the pool. This set-up is best when only single pipework is available from pool and doesn’t have individual
heating pipework. Efficient with only one pump working.
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 Wi-Fi connection. If no Wi-Fi is present then additional external timer
may be required (sold separately)
6. On the single pump controller, connect the black power cable to a 240V GPO, connect the piggyback cord into the chlorinator, and plug the
pump into the bottom of the controller.
7. Connect the Fig 8 wire from the single pump controller to the P1-P2 terminals. (See single pump controller manual for more information
8. Adjust parameter “P6” to 100 as per section E
