Example:
You would like to heat DHW twice daily, i.e. from 22:00 h until
06:00 h the following day, and then from 08:00 h until 09:00 h.
As the day begins at 00:00 h; you have to begin programming at
00:00 h also for this example.
- The first switching time pair runs from 00:00 h until 06:00 h.
- The second switching time pair runs from 08:00 h until 09:00
h.
- The third switching time pair runs from 22:00 h until 24:00 h.
5.3.3 Party program
In the party program you can extend the comfort mode by a few
hours for heating.
5.3.4 Holiday program
In the holiday program, the heat pump system runs in ECO mode,
and frost protection for DHW heating is enabled.
For both the start and end of the holiday, enter the year, month
and day. The start time is 00:00 h on the first day of the holiday.
The end time is 24:00 h on the day the holiday ends. After the
holiday period has expired, the heat pump system switches back
to the previous heating and DHW program.
5.3.5 Heat-up program
Note
The HEAT-UP PROGRAM menu item is protected by a
code and can only be accessed and set by a qualified
contractor.
Heat-up program for underfloor heating systems
Use the heat-up program to dry your screed with a defined tem-
perature profile. To prevent damage to the appliance and/or the
installation, observe the following:
The heat-up program / screed drying must be carried out via the
emergency/booster heater. Never use the heat pump to perform
screed drying as this would place too high a demand on the heat
source and could damage it.
If you use the heat-up program, input the following settings at
the heat pump manager:
First set parameter “LOWER APP LIMIT HZG” to 30°C.
There are a total of 6 parameters that serve to determine the tem-
peratures and periods for the heat-up program. These 6 parame-
ters can be adjusted in sequence as soon as the heat-up program
is activated. The program is started with the HEAT-UP PROGRAM
parameter and the setting ON. Please note that depending on the
system temperature it may take some time to reach the required
low end temperature.
The low end temperature (parameter LOW END TEMPERATURE)
is held for the selected time (parameter DURATION BASE TEMP).
After expiry of this period, the system heats to the maximum low
end temperature (parameter MAXIMUMTEMPERATURE) using
an increase K/day (parameter RISEPERDAY) and holds this max-
imum temperature for the selected time (parameter MAXTEM-
PERATUREDURATION). The system subsequently returns to the
low end temperature using the same steps as for heat-up.

If a heating buffer cylinder has been integrated into the system,
the temperature in the buffer cylinder is controlled solely via the
return sensor (fitted at the base of the buffer cylinder). If only the
direct heating circuit 1 is operational, the set values are reduced
by 5K to even out temperature differences in the buffer cylinder.
If 2 heating circuits are operational (second heating circuit is for
underfloor heating system), the mixer in heating circuit 2 regulates
down to the selected set values.
During the heat-up program the appliance often reaches maxi-
mum output. For this reason, energy consumption and noise levels
are comparatively high during screed drying.
After the heat-up process all modified parameters must be reset
to their standard values or system values.
Emergency operation is not possible while the heat-up program
is active.
