[E‑03]
▪ 0:
No heater
▪ 1:
External heater
Emergency
When the heat pump fails to operate, the optional external backup
heater kit 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
(or
auto SH normal/DHW
off
)
(1)
and a heat pump failure occurs, the backup heater
automatically takes over the heat load.
▪ When
Emergency
is set to
Manual
and a heat pump failure
occurs, the 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.
(1)
auto SH normal/DHW off
has the same effect as
Automatic
, but should NOT be used because there is no domestic hot water.
