Servo-control of circulating pump

If you have connected a circulating pump to terminals P
when the heat pump operates.
When the heat pump is on standby, the circulating pump is powered intermittently in order to monitor the
water temperature in the pool.
Servo-control mode for circulating pump (Setting 10)
When you activate your heat pump, the circulating pump starts up, followed 1 minute later by the heat
pump compressor. When the heat pump stops working, its compressor and fan shut down, and the circu-
lating pump stops after 30 seconds. During a de-icing cycle, the circulating pump will continue to operate
irrespective of the selected mode.
Mode 0: By selecting this mode, the heat pump will automatically put the circulating pump into continuous
operation. Once the circulating pump is operating, the heat pump will start up 1 minute later. Next, when the
required temperature is reached, the heat pump will stop working but will not stop the circulating pump, so
as to ensure a constant circulation of water in your heat pump.
Mode 1 (default): This mode has been designed to maintain filtration in your pool without using the
timetable programmer. When the required temperature is reached, the heat pump will go on standby, then
30 seconds later the circulating pump will shut down.
The circulating pump will then be reactivated in special mode: 2 minutes operation, 15 minutes shut down
(Setting 11 = 15 by default, adjustable from 3 to 20 minutes), thus maintaining regular filtering of your pool.
With a temperature sensor in the heat exchanger compartment, this mode allows your heat pump to update
your pool's actual temperature every 15 minutes. We therefore recommend this mode.
It is only when the pool temperature goes down by 3°C in relation to the required temperature that the
filtration pump and the heat pump resume their normal operating mode.

Using the pressure gauge

The gauge is for monitoring the pressure of the refrigerant contained in the heat pump.
The values it indicates can vary considerably, depending on the climate, temperature and atmospheric
pressure.
When the heat pump is in operation:
The gauge's needle indicates the refrigerant pressure.
Mean operating range between 250 and 400 PSI, depending on the ambient temperature and atmospheric
pressure.
When the heat pump is shut down:
The needle indicates the same value as the ambient temperature (within a few degrees) and the corre-
sponding atmospheric pressure (between 150 and 350 PSI maximum).
If left unused for a long period of time :
Check the pressure gauge before starting up the heat pump. It must indicate at least 80 PSI.
If the pressure goes down too much, the heat pump will display an error message and automatically go into
'safe' mode.
This means that there has been a leakage of refrigerant and that you must call a qualified technician to
replace it.
