postponed or stopped here)
Figure 33(b): DHW Test Complete screen
NOTE: It is possible to postpone the DHW test if
necessary (for example, to run a defrost, because of
time constraints or due to a larger cylinder), by
selecting ‘Finish’ on the DHW test screen as shown in
figure 33(c). If the test is postponed, DHW can still be
used.
Selecting ‘Stop test’ will cancel the test completely. If
the DHW test has been cancelled rather than
postponed, the information 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).

7.5.2 DHW Test
Before you run the DHW test, you will be asked to
check that the valve (figure 31) is in the DHW position,
as shown on the screen in figure 32. Check that the
red actuator marker changes to the correct position.
When you have completed the valve check and select
‘Next’, you will see the DHW test screen, which
informs that the test can take up to 90 minutes.
Selecting ‘Run test’ begins the DHW test and shows
you the time remaining. During the DHW test, it
will not be possible to run a defrost cycle.
If the test fails, you will see the screen shown in figure
33(a), 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 in figure 33(b), which shows
the maximum temperature that the cylinder can
achieve.
7.6 Disinfection
The temperature and frequency of the disinfection
cycle can be adjusted in this menu. If the temperature
is set to higher than the heat pump can achieve, the
screen shown in figure 34 will appear which notifies
that the immersion heated will be used to reach the
disinfection temperature.
