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
When heating of the DHW by the heat pump is too slow, it may affect a comfortable
operation of the space heating/cooling circuit. If so, allow the backup heater to assist
during DHW operation by setting [4-00]=1 or 2.
INFORMATION
Only for systems with integrated domestic hot water tank: 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 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.
