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
[5.8] [6-0E]
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]
Keep hot function
In case of a long time with small or no domestic hot water consumption the tank
energy levels can drop lower than the required value for comfort. The keep-hot-
function prevents the tank temperature from dropping too much after small
domestic hot water consumption or no domestic hot water consumption before
the tank is heated up again. This can result in the tank heating up sooner (reheat
temperature minus keep-hot hysteresis [6-05]) instead of reheat temperature
minus the heat pump ON hysteresis [6-00] temperature.
# Code
[9.I] [7-08]
When the keep-hot-function is enabled then the reheat of the tank could be
sooner.
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.
Description
Maximum:
The maximum temperature that users can select
