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 Reheat only or Schedule + reheat mode 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 Schedule only mode is selected, it is recommended to program an
Eco action 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.
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.
# Code

Hysteresis (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.
# Code
[5.9] [6-00]
Hysteresis (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.
