ON. The system then heats to the selected
low end temperature (Low end temp para-
meter). This temperature is then held for the
set period (Low end durat parameter). After
expiry of this period, the system heats to the
maximum low end temperature (Max heat
up t) using an increase per day/K (Incr per
day) and holds this maximum temperature for
the selected period (Max temp durat). After
expiry of this period, the system reduces the
temperature back to the low end temperatu-
re in the same stages as per heat-up.
This concludes the heat-up program.
As soon as two heating circuits are operatio-
nal, both will be operated in accordance with
this heat-up program (operation with buffer
cylinder and mixer circuit).
The direct heating circuit 1 (buffer circuit with
return sensor) adopts the heat-up program
set values. The actual temperature inside the
buffer cylinder is higher at the heating flow as
the regulation takes place via the return sen-
sor. The mixer (heating circuit 2) regulates the
temperature back down to the selected set
values in the heat-up program (low end tem-
perature and maximum temperature).
Please note that only the mixer cir-
cuit pump is running when operating with
two heating circuits.
When only the direct heating circuit 1 is ope-
rational, the return sensor is again used for
control. As the actual temperature inside the
buffer cylinder is higher at the heating flow,
this constellation sees 5 K being deducted
from the heat-up program set values (low end
and maximum temperatures).

Summeroperation
The „Summer operation“ parameter allows
you to select the time when summer opera-
tion should be active. Summer operation can
be switched ON or OFF. In total, this function
offers two adjustable parameters.
Under the „Building type“ parameter you can
select, whether the current outside tempera-
ture should be compared with the selected
outside temperature (setting 0) or whether,
subject to building type (setting 1, 2 or 3),
an adjusted outside temperature should be
determined. In both cases, if the current and
the adjusted outside temperature is ≥ of the
selected outside temperature, both heating
circuits (if installed) enter summer operation;
reverse hysteresis –1 K. The display indicates
summer operation when the flap is closed.
When regulating to a fixed temperature, sum-
mer mode is inactive for heating circuit 1.
Outside temperature parameter:
Outside temperature adjustable from 10 °C
to 30 °C
Building type parameter:
Adjustment „0“: The outside temperature will
not be adjusted. The average and the building-
specific outside temperature are identical
to the current outside temperature; direct
comparison between the selected and current
outside temperature.
Adjustment „1“: Mild adjustment (averaging
over a 24 h period) of the outside tempera-
ture, e.g. timber construction with rapid heat
transfer.
Adjustment „2“: Mean adjustment (averaging
over a 48 h period) of the outside temperatu-
re, e.g. solid construction with thermal insulati-
on and average heat transfer.
Adjustment: „3“ Severe adjustment (averaging
over a 72 h period) of the outside temperatu-
re, e.g. house with slow heat transfer.

Pump cycles
Heating circuit pump control
The „Pump cycles“ parameter only
applies to the direct heating circuit 1,
i.e. for heating circuit pump 1.
This parameter can be set to ON or OFF.
With this parameter set to OFF, the heating
circuit pump will not cycle, i.e. it runs con-
stantly and is only switched OFF in summer
operation.
The heating circuit pump start will be cont-
rolled in accordance with a fixed temperature
curve of the outside temperature, as soon as
this parameter is set to ON.
The heating circuit pump start impulse is al-
ways 5 minutes.
The heating circuit pump for HC1 also always
starts with each heat pump start. The pump
runs on for 5 minutes after the heat pump has
been switched OFF.
Now the start-up duration is brought to bear,
e.g. at an outside temperature of 5° C, the
pump starts three times per hour for 5 minu-
tes respectively
The return sensor is masked as soon as the
heating circuit pump is switched OFF. Each
time the heating circuit pump is started again,
the return sensor is masked for three minutes.
Pump kick
To prevent the pump from seizing up, for
example during summer, 24 hours after the
pump was last switched OFF, it will be started
for 10 s. This applies to all pumps.
