# Code Description
[9.3.7] [5-01] Equilibrium temperature: Outdoor
temperature below which operation of
the backup heater is allowed.
Range: ‑15°C~35°C
Operation
# Code Description
[9.3.8] [4‑00] Backup heater operation:
▪ 0: Restricted
▪ 1: Allowed
▪ 2: Only DHW Enabled for domestic hot
water, disable for space heating
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 and either automatically or non-
automatically take over the heat load.
▪ When auto emergency is set to Automatic and a heat pump failure
occurs, the backup heater will automatically take over the heat
load and the domestic hot water production.
▪ When auto emergency is set to Manual and a heat pump failure
occurs, the domestic hot water and space heating operation will
stop and need to be recovered manually via the user interface. To
recover operation manually, go to the Malfunctioning main menu
screen, where the user interface will then ask you to confirm
whether the backup heater can take over the heat load or not.
Emergency
We recommend to set Emergency to Automatic if the house is
unattended for longer periods.
# Code Description
[9.5] N/A ▪ 0: Manual
▪ 1: Automatic
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 room frost protection function, the underfloor
heating screed dryout function, and the water pipe
antifreeze function will remain active even if the user does
NOT confirm emergency operation.
Balancing
Priorities
For systems with an integrated domestic hot water tank
# Code Description
[9.6.1] [5‑02] Space heating priority: Defines whether
backup heater will assist the heat pump
during domestic hot water operation.
Enable this function to shorten tank
heating operation time and interruption
of the space heating cycle.
This setting MUST always be 1.
[5‑01] Equilibrium temperature and
[5‑03] Space heating priority
temperature are related to backup
heater. So, you must set [5‑03] equal or
a few degrees higher than [5‑01].
If the backup heater operation is limited
([4‑00]=0) and the outdoor temperature
is lower than setting [5‑03], the
domestic hot water will not be heated
with the backup heater.
[9.6.2] [5‑03] Priority temperature: Defines the
outdoor temperature which below the
backup heater will assist during
domestic hot water heating.
[9.6.3] [5-04] Offset BSH setpoint: Set point
correction for domestic hot water
temperature: set point correction for the
desired domestic hot water
temperature, to be applied at low
outdoor temperature when space
heating priority is enabled. The
corrected (higher) set point will make
sure that the total heat capacity of the
water in the tank remains
approximately unchanged, by
compensating for the colder bottom
water layer of the tank (because the
heat exchanger coil is not operational)
with a warmer top layer.
Range: 0°C~20°C
Timers for simultaneous space and domestic hot water
operation request
# Code Description
[9.6.4] [8-02] Anti-recycle timer: Minimum time
between two cycles for domestic hot
water. The actual anti-recycling time also
depends on setting [8-04].
Range: 0~10 hours
Remark: The minimum time is 0.5 hours
even when the selected value is 0.
[9.6.5] N/A Minimum running timer:
Do NOT change.
