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
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.
Description
▪
The capacity difference between the second
and first step of the backup heater at nominal
voltage. Nominal value depends on backup
heater configuration.
Description
Equilibrium: Deactivate backup heater (or
external backup heat source in case of a bivalent
system) above the equilibrium temperature for
space heating?
▪
0: No
▪
1: Yes
Equilibrium temperature: Outdoor
temperature below which operation of the
backup heater (or external backup heat source in
case of a bivalent system) is allowed.
Range: –15°C~35°C
Description
Backup heater operation:
▪
