11 TEST RUN
Test run is on.
Heat mode is on.
Leaving water temperature is
15°C
CONFIRM
Fig. 95
The logic establishes that:
• the unit switches on in Heating mode, with water supply setpoint at 35°C
• the actual water supply temperature is shown on the HMI display after 10 minutes:
• if present, the backup boiler (AHS) starts in support of the heat pump. If the conditions for exiting the
function are not reached, the boiler continues to operate for 10 minutes, then switches o.
• if present, the backup electric heater (IBH) starts in support of the heat pump. If the conditions for
exiting the function are not reached, the heater continues to operate for 3 minutes, then switches o.
• the unit continues to operate until the setpoint is reached or for 30 minutes

The logic establishes that:
• the unit starts in DHW mode, with a DHW setpoint of 55°C
• the actual water and DHW storage tank supply temperatures are shown on the HMI display
• after 10 minutes, if present, the storage tank electric heater (TBH) starts in support of the heat pump. If the
conditions for exiting the function are not reached, the heater continues to operate for 3 minutes, then
switches o
• the unit continues to operate until the setpoint is reached or for 20 minutes
