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- The pump output switch relay labelled P1 – P2 in the heat pump can activate the filtration pump
through the single pump controller (MJ-Box), therefore being able to run the heat pump
individually with the same pump
2- Relay switch P1 – P2 are initiated as soon as the heat pump is turned on, the output will run the
circulation pump until the heated water reaches the set temperature or is switched off by the WiFi
timers.
3- If the unit reached temperature still within the timer set points, the unit will test the water by starting
the filtration pump once an hour for 2 minutes to get an accurate temperature reading and will
start heating process again if required.
4- When Wi-Fi timers are set through the app Relay switch will run the pump output accordingly.
5- Timers for the heat pump are on the Wi-Fi app (If no WiFi available additional timer may be
required) internal setting require changing to suit this operation.
6- See electrical diagram supplied with M-box for further information.
