Remark: Logic of filtration pump control
*We do NOT recommend the heat pump is used to control the filtration system.*
Reasons: If ambient temperatures keep the body of water above or at the set temperature, Filtration/pump
will not come on, the ability to filter and/or sanitize that body of water will be lost.
Also, the WARRANTY will not cover "blown" mother boards (PCB`s) due to faulty wiring of water pump OR a
water pump becoming defective also causing damage to the heat pump.
Option 1; P3=0 Filtration pump is related to heat pump operation to start and stop.
Filtration pump starts 60s before compressor, filtration pump start 30s and then the water flow switch detect
flow. Before the heat pump enters into Standby mode, the compressor stops first and after 5 minutes filtration
pump stops.

2. After 1 hour, the filtration pump
will restart for 5 minutes. If it tests

Option 2; P3=1 Filtration pump is always on, P2=0 the timer function is no active
Under condition P3=1, whenT1≥Tset+1
℃
(T1≥29
℃
)last for 3 minutes, heat pump will be in standby, while
filtration pump is always on.
Under option 2, with activation of the timer; P2=1 to start and stop the filtration pump according the
programming of the P4 (time), P5 (Timer ON) and P6 (Timer OFF)
Condition for the heat pump start, timer ON actives;
When the timer reaches the set time of TIMER ON , the filtration pump will start and after 5 minutes the
heat pump start. The heat pump stays in stop if the water in temperature is ≥ Tset+1
℃
,before the TIMER OFF,
the filtration still activated.
Condition to stop the heat pump, timer OFF actives;
Before the TIMER OFF, the heat pump stops and the filtration is still activated. When timer reaches the set
time of the TIMER OFF, the heat pump will stop and after 5 minutes the filtration pump stops.
NOTE:
Tset = Tseting water temperature, for example: Tset = 28
℃
Tseting water temperature in your pool heat
pump
Tset-0.5 = less 0.5

than Tseting temperature, Tset+ 0.5 = 28+0.5=28.5
