Hi all i have been asked by a friend to look at his heat pump ( An Air Energy 550Ti1 ) for his pool, it seems that when he sets the temperature to 32 degrees c, the monitor says 32 but the water temperature is actually 25 degrees c.

The system runs on R407C and the pressures are

70psi suction i presume and 300 discharge.

The water sensor seems fine.

Can anyone shed some light on why the water temperature is not reading what it says on the controlls.
