Menu: SETTINGS
Once this setting has been selected, the DHW STAGES parameter
must be set to "0", as the heat pump no longer provides DHW
heating.
 DUAL MODE TEMP WW
Dual mode temperature (outside temperature) of the heat pump
for DHW heating.
Depending on the parameter set (SUPPORTED, ALONE, INDEPEND-
ENT), the second heat source is responsible for DHW heating.
 LOWER APP LIMIT WW
Lower application limit of the heat pump for DHW heating.
The heat pump is switched off at outside temperatures below the
selected lower DHW application limit. The second heat source is
solely responsible for DHW heating.
 WW PWM
This is where you determine the percentage output with which
the second heat source will provide DHW heating.
 WW 0-10 V
This is where you determine the percentage output with which
the second heat source will provide DHW heating.
 DHW CIRCULATION
With the DHW circulation function, DHW can quickly be delivered
to the draw-off points. The DHW circulation pump pumps hot
water through the DHW circulation line to the draw-off points to
rapidly make hot water available there. At the same time, however,
the DHW cylinder cools down.
 DEMAND
The DHW circulation function can be requested in various ways.
 Choose the conditions that activate the DHW circulation
function.
 PROGRAM
To minimise cooling, the DHW circulation pump is controlled via a
time program so that the pump runs only in the specified periods.
Three switching times can be set per day. Equally, it is possible
to set a block pattern for the whole week, for weekdays or for
weekends.
 Set the times in the PROGRAMS/ DHW CIRCULATION PRO-
GRAM menu.
 PROGRAM + INPUT
The DHW circulation pump is linked to the time program and the
input. A pressure sensor must be installed in the DHW circulation
line. If water pressure drops due to the use of a draw-off point, the
sensor switches a relay. This switching output is linked to the DHW
circulation sensor input and the sensor earth, so the switching
is recognised as a short circuit and thus the pump switches on.
 Set the times in the PROGRAMS/ DHW CIRCULATION PRO-
GRAM menu.
 PROGRAM + SENSOR
The DHW circulation pump is linked to the time program and the
input. If the temperature measured by the DHW circulation sensor
falls below the set temperature during the set times, the pump
is switched on.
 Set the times in the PROGRAMS/ DHW CIRCULATION PRO-
GRAM menu.
 SET TEMPERATURE
In this menu item you can set the set temperature for the DHW
circulation function.
If the temperature falls below the set temperature, the DHW cir-
culation pump starts.
 HYSTERESIS
If the sum of the DHW circulation temperature and the set hys-
teresis is greater than the set temperature, the DHW circulation
pump is switched off.
 HYBRID MODULE
If a hybrid module is used to integrate a second heat generator,
you can make the necessary settings here.
 2ND HEAT GENERATOR TYPE
In this menu, you set the type of external heat generator.
 GAS CONDENSING
 Activate this parameter if this is your external heat generator.
 GAS NON-CONDENSING
 Activate this parameter if this is your external heat generator.
 OIL CONDENSING
 Activate this parameter if this is your external heat generator.
 OIL NON-CONDENSING
 Activate this parameter if this is your external heat generator.
 2ND HEAT GENERATOR SETTING
 SET TEMPERATURE
With this parameter, you can select the set temperature for the
external heat generator.
If the set temperature selected here is undershot, the external
heat generator switches on.
