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 [5.7.3] with
defined duration [5.7.5] 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 turn off domestic hot water
operation during disinfection.
Maximum DHW temperature setpoint
The maximum temperature that users can select for the domestic
hot water. You can use this setting to limit the temperatures at the
hot water taps.
INFORMATION
During disinfection of the domestic hot water tank, the
DHW temperature can exceed this maximum temperature.
INFORMATION
Limit the maximum hot water temperature according to the
applicable legislation.

Maximum
The maximum temperature that users
can select for the domestic hot water.
You can use this setting to limit the
temperature at the hot water taps.
The maximum temperature is NOT
applicable during disinfection function.
See disinfection function.
Hysteresis
The following ON hysteresis can be set.
Heat pump ON hysteresis
Applicable when domestic hot water preparation is reheat only.
When the tank temperature drops below the reheat temperature
minus the heat pump ON hysteresis temperature, the tank heats up
to the reheat temperature.
The minimum ON temperature is 20°C, even if setpoint hysteresis is
smaller than 20°C.

▪ 2°C~40°C
Reheat hysteresis
Applicable when domestic hot water preparation is scheduled
+reheat. When the tank temperature drops below the reheat
temperature minus the reheat hysteresis temperature, the tank heats
up to the reheat temperature.
