Integrated
The backup heater will also be used
for domestic hot water heating.
Emergency
When the heat pump fails to operate, the backup heater or boiler 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 or boiler 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 or boiler 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.

INFORMATION
The auto emergency setting can be set in the menu
structure of the user interface only.
INFORMATION
If a heat pump failure occurs and
Emergency
is set to
Manual
, the following functions will remain active even if
the user does NOT confirm emergency operation:
- Room frost protection
- Underfloor heating screed dryout
- Water pipe freeze prevention
However, the disinfection function will be activated ONLY if
the user confirms emergency operation via the user
interface.
INFORMATION
If the boiler is connected as auxiliary heat source to the
tank (via bivalent coil or via drain back connection), the
boiler and NOT the backup heater operates as emergency
heater, independent of the boiler capacity. For small
capacity boilers this may lead to capacity shortages in
case of emergency.
If the boiler is directly connected to the space heating
circuit, it does NOT act as emergency heater.
Number of zones
The system can supply leaving water to up to 2 water temperature
zones. During configuration, the number of water zones must be set.
INFORMATION
Mixing station.
If your system layout contains 2 LWT
zones, you need to install a mixing station in front of the
main LWT zone.
