 DHW
 DHW TEMPERATURES
 In the menu item for the DHW temperature, you can
specify the set temperatures for comfort and ECO modes.
 COMFORT TEMPERATURE
Select COMFORT TEMPERATURE to set the set DHW temperature
for comfort mode. When the heat pump is in comfort mode (see
PROGRAMS/ DHW PROGRAM), the heat pump heats the DHW to
the value set here.
 ECO TEMPERATURE
Select ECO TEMPERATURE to set the set DHW temperature for ECO
mode. When the heat pump is ECO mode (see PROGRAMS/ DHW
PROGRAM), the heat pump heats the DHW to the value set here.
 STANDARD SETTING
 DHW MODE
With this parameter, you can specify the type of DHW heating.
Three types of DHW heating are available:
- Priority operation
- Parallel operation
- Partial priority operation
 PRIORITY OPERATION
If you enable priority operation, the heat pump specified for DHW
and the corresponding DHW charging pump are switched on in
response to DHW demand.
The remaining heat pumps in the cascade are switched off for
heating mode.
 PARALLEL OPERATION
If you enable parallel operation, the DHW charging pump and
associated buffer charging pump are switched on in response to
DHW demand.
The remaining heat pumps in the cascade are switched off for
heating mode.
 PARTIAL PRIORITY
If you enable partial priority operation, the heat pump specified
for DHW and the corresponding DHW charging pump are switched
on in response to DHW demand.
The remaining heat pumps in the cascade are switched on for
heating mode.
 DHW HYSTERESIS
With this parameter, you can specify the switching hysteresis for
DHW heating.
 Set how large the temperature differential to the set DHW
temperature has to be in order to start DHW heating.
DHW heating starts when the temperature falls below the set DHW
temperature minus the hysteresis.
Once the set DHW temperature is reached, DHW heating ceases.
 DHW STAGES
With this parameter you can set the number of heat pump stages
for DHW heating.
 AUTOMATIC DHW CONTROL
Note
If you want to use automatic DHW control, all DHW stages
must be allowed.
If automatic DHW control is enabled, then depending on the out-
side temperature and the load required, all DHW stages can be
activated.
 OUTSIDE TEMPERATURE
The heating output of an air/water heat pump decreases as the
outside temperature falls. DHW heating always starts with the first
stage. To meet the energy demand for DHW heating, additional
DHW stages are automatically enabled subject to the outside tem-
perature set here.
 Set the outside temperature from which the additional DHW
stages should be enabled.
 WW LEARNING FUNCTION
With this parameter you can set whether the set DHW temperature
is adjusted automatically during DHW heating.
ON
If the heat pump is shut down by the HP sensor (high pressure
sensor) or due to the maximum hot gas temperature, DHW heating
is terminated. The set DHW temperature is overwritten with the
current actual DHW temperature. The new set DHW temperature
is then applied to DHW mode.
DHW heating takes place solely through the heat pump. The in-
ternal electric emergency/booster heater or external heat source
remains deactivated.
OFF
When the heat pump is shut down by a limiter function, the inter-
nal electric emergency/booster heater or the external heat source
is switched on as a reheating stage until the set DHW temperature
is reached.
 COMBI CYLINDER
In this menu item you can set whether a combi or instantaneous
water cylinder is installed in the heat pump system.
