First Start-Up; Definition Of The Display Codes - Hayward SUMHEAT SHE1901 Guia Del Usuario

First start-up

Before the first start-up, it is important to check that the heat pump is correctly connected
electrically, that the order of phases is respected for the three-phase machines (a green
light comes on on the phase controller located in the electrical box), only the water entry
and exit valves are open and no element disturbs the rotation of the ventilator.
Next, all you have to do is adjust to the desired temperature. The ventilator will start up immedi-
ately. There will be a delay of 3 to 4 minutes before the compressor starts.
When the compressor is in operation, the HEATING light, located to the right of the display,
symbolised by
tion 24/7.
It is also normal to see water dripping from the holes at the base of the unit. This is normal
condensation.

Definition of the display codes

Codes of the analyser
The majority of problems are detected by the self-diagnosis. When a prob-
lem occurs, a corresponding code appears on the digital indicator of your
heat pump.
Display Definition of the codes
OFF
The desired temperature which is programmed is lower than 17 °C (63 °F).
LP & LP3
No refrigerant fluid in the unit or low pressure controller faulty.
The digital display will display the LP3 code after having displayed the LP code three
times and will then deactivate your heat pump.
HP & HP3 Low water output to the unit or high pressure controller faulty. Check the water output.
Clean your filter, check the skimmers panel and pump. The digital display will display the
HP3 code after displaying the HP code three times and will then deactivate your heat
pump in order to protect it.
Po
The water temperature probe connected to the WS edge may be disconnected.
If it isn't, the probe is possibly in open or defective contact.
Pc
The water temperature probe may be short-circuited or faulty.
FLo & FL3
Possible causes:
- The valve of the filter is not in "Filtration" position.
- The filtration pump has stopped.
- The filter is dirty.
- Lack of water at the level of the filtration pump.
- The water pressure switch must be adjusted, or it is damaged.
- The device is in protection mode and will display FL3. Press any key to restart the unit.
The FL3 code deactivates your heat pump in order to protect you.
dPo
The de-icing probe connected to DS on the electronic card may be disconnected.
If it isn't, the probe is possibly in open or faulty contact.
dPc
The de-icing probe may be short-circuited or faulty.
FS
Device presently in de-icing cycle (the ventilator is working, but the compressor is on
stop). This is normal when the external temperature is low.
