8 – Environment problem
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 E 12 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 water
In cooling mode:
- too important water flow: open the by pass valve for decreasing the water flow and
so the exchange water 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.
9 – Error codes:
This table explains the error codes caused by a defective regulating
component or by a security operation.

Cause Solution
E 03 Water over heating fault
Water flow not enough
Water flow switch fault
Check the water pump
Pipe block
E 04 Anti-freezing protection
