6.2.4 Heating priority (see the paragraph 6.9), option of connection
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.
Condition Example Water pump working logic

P3=0,
T1≥Tset-0.5℃,

T1≥27.5℃,
last for 30

1. Then it enters into
standby mode for 1 hour
(It will not restart except
turn it on manually.)
2. After 1 hour, the filtration pump
will restart for 5 minutes. If the
T1≤27
℃
, the heat pump will start
to work until T1≥27.5
℃
and last for
30 minutes to go into standby
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 is still activated.
Condition to stop the heat pump, timer OFF actives;
When the timer reaches the set time of the TIMER OFF, the heat pump will stop and after 5 minutes the
filtration pump stops.
NB; Symbol of automatic TIMER start , the light will be on when it is in operation, symbol of automatic
TIMER stop , the light will be on when it is in operation. Outside the time operation the display will be
advise by OFF.
If heat pump is turned ON/OFF manually, the filtration pump will start and stop accordingly.
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=27.5
℃
Tset+0.5= more 1
℃
than Tseting temperature, Tset+ 0.5 = 28+0.5=28.5
℃
