The backup heater will also be used
for domestic hot water heating.
(a)
Use the menu structure instead of the overview settings. Menu
structure setting [9.2.1] replaces the following 3 overview settings:
• [E-05]: Can the system prepare domestic hot water?
• [E-06]: Is a domestic hot water tank installed in the system?
• [E-07]: What kind of domestic hot water tank is installed?
Emergency
When the heat pump fails to operate, the backup heater can serve
as an emergency heater. It then takes over the heat load either
automatically or by manual interaction.
▪ When
Emergency
is set to
Automatic
and a heat pump failure
occurs, the backup heater automatically takes over the domestic
hot water production and space heating.
▪ When
Emergency
is set to
Manual
and a heat pump failure
occurs, the domestic hot water heating and space heating stops.
To manually recover it via the user interface, go to the
Malfunctioning
main menu screen and confirm whether the
backup heater can take over the heat load or not.
▪ Alternatively, when
Emergency
is set to:
▪
auto SH reduced/DHW on
, space heating is reduced but
domestic hot water is still available.
▪
auto SH reduced/DHW off
, space heating is reduced and
domestic hot water is NOT available.
▪
auto SH normal/DHW off
, space heating operates as
normally but domestic hot water is NOT available.
Similarly as in
Manual
mode, the unit can take the full load with
the backup heater if the user activates this via the
Malfunctioning
main menu screen.
To keep energy consumption low, we recommend to set
Emergency
to
auto SH reduced/DHW off
if the house is unattended for longer
periods.
