SOURCE: loss of temperature control
Is the heater staying on all the time? Most likely cause of themostat trouble is the sensor. Try to find it and measure its resistance at different temps to verify the trouble.

just check your water supply of your aristion DIA 20-24 combi boiler if is in constant pressure. not properly circulated water supply can cause overheating.
and manuals can help us also in proper checking. at the link below please check this out if you don't have.

hope this is helpful. On my potterton 24 combi boiler it is the valve that sits the lowest, with a slight indent in the black tap. if you turn this for a short period you will hear a hiss and the pressure will quickly build to the desired pressure, when you can them turn the tap back off.

It sounds as if you you have a low charge of refrigerant, r22. When the unit comes on outside, the outdoor coils become the lowside, there is a low pressure switch that is tripping out contactor protecting the compressor.

You definetly have a control issue. However trying to diagnose the exact problems that you have would be very difficult without actually seeing the wiring. You defintely have a wiring/control issue but I cannot tell you exactly what it is without more info. Sorry, I would love to help you more...
