WARNING
Be aware that the domestic hot water temperature at the
hot water tap will be equal to the value selected in field
setting [2-03] after a disinfection operation.
When the high domestic hot water temperature can be a
potential risk for human injuries, a mixing valve (field
supply) shall be installed at the hot water outlet connection
of the domestic hot water tank. This mixing valve shall
secure that the hot water temperature at the hot water tap
never rise above a set maximum value. This maximum
allowable hot water temperature shall be selected
according to the applicable legislation.
CAUTION
Be sure that the disinfection function start time [A.4.4.3]
with defined duration [A.4.4.5] is NOT interrupted by
possible domestic hot water demand.
INFORMATION
In case of error code AH and no interruption of the
disinfection function occurred due to domestic hot water
tapping, following actions are recommended:
When the Domestic hot water > Type > Reheat or
Reheat + sched. is selected, it is recommended to
program the start-up of the disinfection function at least
4 hours later than the last expected large hot water
tapping. This start-up can be set by installer settings
(disinfection function).
When the Domestic hot water > Type > Scheduled only
is selected, it is recommended to program a Storage
eco 3 hours before the scheduled start-up of the
disinfection function to preheat the tank.
INFORMATION
Disinfection function is restarted in case the domestic hot
water temperature drops 5°C below the disinfection target
temperature within the duration time.
INFORMATION
An AH error occurs if you do the following during
disinfection:
Set the user permission level to Installer.
Go to the DHWtank temperature home page (Tank).
Press to interrupt the disinfection.
Heat source settings
Auto emergency
When the heat pump fails to operate, the gas boiler can serve as an
emergency back-up heater and either automatically or non-
automatically take over the entire heat load. When auto emergency
is set to : Automatic and a heat pump failure occurs, the boiler will
automatically take over the heat load. When a heat pump failure
occurs and auto emergency is set to Manual the domestic hot water
and space heating operations will stop and need to be recovered
manually. The user interface will then ask the user to confirm
whether the boiler can take over the entire 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 that setting
[A.5.1.2] Emergency shall be set to Automatic.
# Code Description
[A.5.2.1] N/A Defines whether in an emergency
situation the gas boiler is allowed to
automatically take over the entire heat
load or whether manual confirmation is
required.
0: Manual (default)
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 [A.5.1.2] 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.
Equilibrium temperature
Based on the ambient temperature, energy prices and the required
leaving water temperature, the user interface is able to calculate
which heat source can deliver the required heating capacity most
efficiently. However, to maximise the energy output of the heat
pump, it is possible to prevent the gas boiler from operating when
the ambient temperature exceeds a certain point (e.g. 5°C). This can
be useful to avoid too much gas boiler operation in case of incorrect
settings. When an equilibrium temperature is set, domestic hot water
operation is NEVER prohibited.
# Code Description
N/A [5‑00] Defines if gas boiler operation is allowed
when the ambient temperature exceeds
the set equilibrium temperature during
space heating operation.
0: allowed (default).
1: NOT allowed.
N/A [5‑01] Equilibrium temp.
When the ambient temperature is higher
than this temperature, the gas boiler is
NOT allowed to work. Only applicable if
[5‑00] is set to 1.
Range: –15°C~35°C (default: 5°C)
System settings
Priorities
# Code Description
N/A [C‑00] If a solar kit is installed, what has
priority to heat up the tank?
0: Solar kit (default)
1: Heat pump
Auto-restart
When power returns after a power supply failure, the auto restart
function reapplies the remote controller settings at the time of the
power failure. Therefore, it is recommended to always enable the
function.
If the preferential kWh rate power supply is of the type that power
supply is interrupted, always enable the auto restart function.
Continuous indoor unit control can be guaranteed independent of the
preferential kWh rate power supply status, by connecting the indoor
unit to a normal kWh rate power supply.
