Operation
# Code Description
[9.3.8] [4‑00] Backup heater operation:
▪ 0:
Restricted
▪ 1: Allowed
▪ 2: Only DHW : Backup heater operation is
enabled for domestic hot water and disabled
for space heating.
INFORMATION
If backup heater operation during space heating needs to be limited but can be
allowed for domestic hot water operation, then set [4‑00] to 2.
Emergency
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.
