Auto emergency
When the heat pump fails to operate, the backup heater and booster
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.
▪ The booster heater will automatically take over 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 operations will
stop and need to be recovered manually. The user interface will
then ask you to confirm whether the backup heater or booster
heater can take over the heat load or not.
When the heat pump fails, will appear on the user interface. If the
house is unattended for longer periods, we recommend to set
[A.6.C] Emergency to Automatic.

Code
Description
[A.6.C]
N/A
Emergency:
▪ 0: Manual (default)
▪ 1: Automatic
INFORMATION
If [4‑03]=1 or 3, then Emergency=Manual is not applicable
for the booster heater.
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 [A.6.C] 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.

Priorities (for systems with a domestic hot water tank)

Code
Description
N/A
[5-02]
Space heating priority.
Defines whether domestic hot water is
made by booster heater only when
outdoor temperature is below space
heating priority temperature. It is
recommended to enable this function to
shorten tank heating operation time
and guaranteed domestic hot water
comfort.
▪ 0: disabled
▪ 1: enabled
[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].
N/A
[5-03]
Space heating priority temperature.
Defines the outdoor temperature which
below the domestic hot water will be
heated by booster heater only.
Range: –15°C~35°C (default: 0°C).
#
Code
Description
N/A
[5-04]
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 (default: 10°C).
Auto-restart
When power returns after a power supply failure, the auto restart
function reapplies the user interface settings at the time of the power
failure. Therefore, it is recommended to always enable this function.
If the power supply might get interrupted (e.g. preferential kWh rate
power supply), always enable the auto restart function. Continuous
control of the hydro part of the outdoor unit can be guaranteed
independent of the preferential kWh rate power supply status, by
connecting the hydro part of the outdoor unit to a normal kWh rate
power supply.

Is the auto restart function of the unit
allowed?
▪ 0: No
▪ 1 (default): Yes
Preferential kWh rate power supply
#
Code
Description
[A.2.1.6]
[D‑01]
Connection to a preferential kWh rate
power supply:
▪ 0 (default): The refrigerant part of the
outdoor unit is connected to a normal
power supply.
▪ 1: The refrigerant part of the outdoor
unit is connected to a preferential kWh
rate
power
supply.
When
the
preferential kWh rate signal is sent by
the electricity company, the contact
will open and the unit will go in forced
off mode. When the signal is released
again, the voltage-free contact will
close and the unit will restart
operation. Therefore, always enable
the auto restart function.
▪ 2: The refrigerant part of the outdoor
unit is connected to a preferential kWh
rate
power
supply.
When
the
preferential kWh rate signal is sent by
the electricity company, the contact
will close and the unit will go in forced
off mode. When the signal is released
again, the voltage-free contact will
open and the unit will restart
operation. Therefore, always enable
the auto restart function.
