NOTE: Selecting ‘Stop test’ will cancel the test completely. If the DHW test
has been cancelled rather than postponed, the information regarding the
immersion displayed on the set temperature menu for DHW will not be correct
(the immersion will not be used until the maximum temperature achievable by
the heat pump has been reached).

If the test fails, you will see the screen shown on the left in gure 30, which provides information on why
the test failed, and advice on checks to carry out.
If the test is complete and has been successful, you will see the screen shown on the right in gure 30,
which shows the maximum temperature that the cylinder can achieve.
4.4.10 Disinfection (thermal)
Thermal disinfection is a function which keeps the level of legionella bacteria
in the cylinder under acceptable levels. This is carried out by heating the hot
water in the cylinder to a high temperature for a minimum set time.
The temperature and frequency of the disinfection cycle can be adjusted in this
menu.
Figure 31: Disinfection setup
If the temperature is set to above what the heat pump can achieve, text on the screen will appear which
noties that the immersion heater will be used at the end of the cycle to top up to the required disinfection
temperature.
