System-specific parameters
Different maximum temperatures are
permissible for panel and radiator heating
systems. The upper limit of the return set
temperature can be set between 25 °C and 70
°C.
The return set temperature hysteresis forms
the neutral zone for operation of the heat pump.
If the temperature "Return set temperature plus
hysteresis" is reached, the heat pump switches
itself off. If the temperature "Return set
temperature minus hysteresis" is reached, the
heat pump switches itself on.
Settings to lower the heating characteristic
curve of heating circuit 1
Sets the time during which the temperature in
heating circuit 1 is to be lowered
Sets the temperature value by which the
heating characteristic curve of heating circuit 1
is to be lowered when the temperature is
lowered
For each day of the week, it is possible to select
whether Time1, Time2, no time or both times
are to be active when the temperature is
lowered. Operations to lower the temperature
that exceed a weekday are activated or
deactivated at the end of each day accordingly.
Settings to raise the heating characteristic
curve of heating circuit 1
Sets the time during which the temperature in
heating circuit 1 is to be raised.
Sets the temperature value by which the
heating characteristic curve of heating circuit 1
is to be raised.
For each day of the week, it is possible to select
whether Time1, Time2, no time or both times
are to be active when the temperature is raised.
Operations to raise the temperature that
exceed a week day are activated or deactivated
at the end of each day accordingly.
Settings for heating circuit 2
The following heating regulation options are
available for heating circuit 2:
* Return temperature regulation based on the
external temperature and the set heating curve
* Return temperature regulation via a fixed-
setpoint (horizontal heating characteristic
curve)
The sensor for heating circuit 2 must always be
installed in the flow. The sensor for mixer
control is used for this.
The heating curve end point should be set
according to the design of the heating system.
For this purpose, the maximum flow
temperature must be entered.
