You would like to heat DHW twice daily, 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, programming for this example must
again start at 00:00 h.
- 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 for heating
by a few hours.
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 0:00 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 menu item HEAT-UP PROGRAM is protected by a
code and can only be accessed and set by a qualified
contractor.
Heat-up program for underfloor heating systems
Never use the heat pump for drying screed, as this places an
excessive demand on the heat source and may cause it to be
damaged. Use the electric emergency/booster heater for the
heat-up program. For this, set LOWER APP LIMIT HEATING and
DUAL MODE TEMP HEATING parameters to 30 °C and start the
heat-up program.
Emergency mode cannot be enabled in the heat-up program.
There are a total of 6 parameters for the heat-up program. These
6 parameters 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 with the setting ON. The system then
heats to the selected low end temperature. The low end temper-
ature is held for the set period (parameter TEMP RISE PERIOD).
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 maxi-
mum 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. This
concludes the heat-up program. As soon as 2 heating circuits
are operational, both will be operated in line with the heat-up
program (operation with buffer cylinder and mixer circuit). Direct
heating circuit 1 (buffer circuit with return sensor) adopts the
set values of the heat-up program. Since this is regulated via the
return sensor, the actual temperature inside the buffer cylinder is
higher at the heating flow. The mixer (heating circuit 2) regulates
the temperature back down to the set values selected in the heat-
up program (low end temperature and maximum temperature).

Please note that only the mixer circuit pump is running when
operating with 2 heating circuits.
If only direct heating circuit 1 is operational, the return sensor is
again used for control. As the actual temperature inside the buffer
cylinder is higher at the heating flow, this configuration results in
5 K being deducted from the set heat-up program values (low end
and maximum temperatures).
The summer logic is disabled whilst the heat-up program runs.
