→ Heating
The back-up boiler supports the heat pump during heating.
The back-up boiler is activated for the anti-legionella function.
→ DHW
The back-up boiler supports the heat pump during domestic hot water
generation.
The back-up boiler is activated for frost protection or de-icing.
→ DHW + heat.
The back-up boiler supports the heat pump during domestic hot water
generation and heating.
Measured temperature, e.g. downstream of the low loss header
In the case of excessive current, the buffer cylinder is heated up to the flow temperature +
set offset via the heat pump. Prerequisite:
–
A photovoltaic installation is connected.
–
Photovoltaics is activated in the HP control module configuration → MI: function.
Factory setting: 10 K
→ Off
The system control always actuates the heat generators in the sequence
1, 2, 3, etc.
→ On
Once a day, the system control sorts the heat generators based on their
actuation time.
The back-up heater is excluded from this sorting.
Prerequisite: The heating installation contains a cascade.
Sequence in which the system control actuates the heat generators.
Prerequisite: The heating installation contains a cascade.
Select whether the external heating circuit is deactivated using a bridge or open terminals.
Prerequisite: The FM5 and/or FM3 functional module is connected.
Factory setting: Bridge,deact.
Setting the time span so that the required room temperature is reached at the beginning of
the first time period.
The start of heating is determined as a function of the outdoor temperature (OT):
–
OT ≤ -20 °C: Set duration of the pre-heating time
–
OT ≥ +20 °C: No pre-heating time
The duration of the pre-heating time is interpolated linearly between these two values.
Factory setting: Off
Set whether the first heat pump or all heat pumps are to be used for the domestic hot water
generation.
Factory setting: All heat pumps
If the outdoor temperature falls below the set temperature value, Heat curve: is used to reg-
ulate to Desired temperature: °C outside of the time periods.
OT ≤ set temperature value: No night set-back or total shut-down
Factory setting: Off
Systems are roughly grouped according to their connected system components. Each group
has a basic system diagram code. Based on the code that is entered, the system control
enables the system-related functions.
You can use the connected components to determine the basic system diagram code for the
installed installation (→ Using the functional modules, basic system diagram, start-up) and
enter this here.
Factory setting: Basic system diagram 1 or 8
Each configuration corresponds to a defined terminal assignment FM5 (→ Chapter 4.5). The
terminal assignment determines which functions contain the inputs and outputs.
Select the configuration that suits the installation that is installed.
Each configuration corresponds to a defined terminal assignment FM3 (→ Chapter 4.6). The
terminal assignment determines which functions contain the inputs and outputs.
Select the configuration that suits the installation that is installed.
