The defrosting is necessary only in heating mode.
Sequences of the defrosting:
1- Start
The defrosting is engaged if the following conditions are at the same time
fulfilled:
- the defrosting sensor temperature goes down to 15°C
- the compressor runs without stopping for 40 minutes
- the defrosting sensor temperature goes down to -7°C
2- The compressor and the fan stop
3- After 25 seconds, the 4 way valve shifts
4- After 5 seconds, the compressor starts alone and the accumulated freeze on
the gills becomes melting, what is generally with a steam cloud
5- Stop:
The defrosting stops if one of the following conditions is fulfilled:
- the detected temperature by the defrost sensor goes up to 15°C.
- the compressor had run totally 6 minutes
6- The compressor stops
7- The fan start
8- After 5 seconds the 4 way valve shifts
9- After 25 seconds the compressor start for restarting in heating mode.
Under certain external conditions the heat exchanges between the refrigerant and
the water on one hand and between the fluid and the air on the other hand are
insufficient; the consequence is that the refrigerating circuit runs up in pressure
and the compressor consumes more electricity.
The temperature sensors compressor outlet and the magnetic circuit breaker
on the compressor power supply protect the compressor from these extreme
conditions; the error messages EE 06 occur.
The condition causing this situation is as follows:
In heating mode:
- insufficient water flow:
close the by-pass valve for increasing the refrigerant exchange à water
In cooling mode:
- too important water flow: open the by pass valve for decreasing the water flow
and so the exchange water à refrigerant
- insufficient air flow: be sure that the real net of condenser are not blocked.
Note: these error codes are likely to occur if temperature of swimming pool water is
high and the ambient air is hot.
