Not connected: The signal of an external control is used to switch
between heating and cooling. Prerequisite: HP off is selected in
the ESCO function.
–
MI contact closed = cooling
–
MI contact open = heating
1 x circulation: In the case of excessive current, a signal is
present and the system control activates the Rapid DHW function
once. If the signal persists, the buffer cylinder is charged to the
flow temperature + buffer cylinder offset until the signal at the heat
pump drops off again.
Photovoltaics: The system control ignores the signal present.
Ext. cooling mode: The end user has pressed the circulation but-
ton. The system control activates the circulation pump for a short
time period.
The system control switches the Cooling function on and guides
the heat from the living room back to the earth via the heat pump.
Prerequisite:
–
The Automatic cooling function is activated
–
The Absence function is active.

Factory setting: Off
Average value for the measured outdoor temperatures in the last
24 hours.
Cooling starts once the outdoor temperature (24-hour average)
exceeds the set temperature.
Factory setting: 15 °C
Enter the upper limit for the outdoor temperature. If the outdoor
temperature rises above the set value, the system control deactiv-
ates heating mode.
Can be set from 10–99 °C, factory setting: 21 °C
The heat curve is the dependence of the flow temperature on the
outdoor temperature for the desired temperature (target room tem-
perature).
Factory setting:
–
1.20 for a conventional heat generator
–
0.60 for a heat pump and/or mixed circuit
Enter the lower limit for the target flow temperature. The system
control compares the set value with the calculated target flow tem-
perature and regulates to the larger value.
Factory setting: 15 °C
Enter the upper limit for the target flow temperature. The system
control compares the set value with the calculated target flow tem-
perature, and regulates to the smaller of these values.
Factory setting:
–
90 ° for a conventional heat generator
–
55 °C for a heat pump and/or mixed circuit
Eco: The heating function is switched off and the frost protection
function is activated. For outdoor temperatures that fall below 4 °C
for longer than four hours, the system control switches the heat
generator on and regulates to the set-back temperature: °C. At an
outdoor temperature above 4 °C, the system control switches the
heat generator off. The monitoring of the outdoor temperature re-
mains active. Heating circuit behaviour outside of the time periods.
Prerequisite:
–
Time-controlled is activated in the Heating → Mode function.
Normal: The heating function is switched on. The system control
regulates to the set-back temperature: °C. Prerequisite:
–
Time-controlled is activated in the Heating → Mode function.
