Menu: Auxiliary heater with mixer
Make the mixed auxiliary heater specific settings in this menu. These
settings are only available if the system is designed and configured
accordingly and the type of appliance used supports this setting.
Menu item
Control range: Function description
Mixed aux. heat.
[230V] The mixed additional heater is controlled by on/off
conn
signal.
[0-10V] The mixed additional heater is controlled based
on power demand.
Delay time for
[0...120] min: Set the delay for opening of the mixing valve
mixer
to allow the auxiliary heater to preheat.
Mixer run time
[1...120...6000] s: Set the runtime for the mixing valve to
go from one end point to the other.
Alarm input logic
[Open contact] | [Closed contact]: Set if the auxiliary
heater has a "NO" or "NC" output for the alarm.
Outs. temp par.

System data
Settings for the entire heating system can be made in this menu.
Menu item
Control range: Function description
Is a buffer cylinder
[Yes] | [No]: Set if a buffer cylinder is installed in the
installed?
heating system.
Config. HC1 at HP [No HC1 on heat appliance]: no heating circuit connected
to the heat source.
[No own heating circuit pump]: heating circuit 1 is directly
connected to the heat pump/indoor unit without heating
circuit pump.
[Via pump PC1]: heating circuit 1 is directly connected to
the heat pump/indoor unit and equipped with a heating
circuit pump.
Internal heating
[Heating pump]: the internal heat source pump also serves
pump
as heating pump in heating circuit 1.
Min. outside temp. Set the design temperature for the system, DUT
(Dimensioning outdoor temperature). This is the lowest
average outdoor temperature for the region. The setting
affects the slope of the heating curve as it is the point
where the heat source reaches the highest flow
temperature.
1)
Damping
[Yes]: the set building type affects the measurement of the
outside temperature. The outside temperature is delayed
(adjusted).
[No]: the measured outside temperature is included
unadjusted in the weather-compensated control.
Building type
Measure of the thermal storage capacity of the heated
building.
1) To get a more responsive regulation it is recommended to choose "No".
Table 10 Settings in the system data menu
HPC 410 – 6721832682 (2021/02)
Building type
If damping is activated, the outside temperature fluctuations are
damped with the building type. By damping the outside temperature,
the thermal inertia of the building mass is taken into account in the
weather-compensated control.
Adjustment
Function definition
Heavy (high
Type
storage capacity)
E.g. brick house
Effect
• Intense damping of the outside temperature
• Long excessive increase in flow temperature with quick
heat-up
Medium (medium
Type
storage capacity)
e.g. house made of hollow blocks (default setting)
Effect
• Medium damping of the outside temperature
• Excessive increase in flow temperature with quick
heat-up of medium duration
Light (low storage
Type
capacity)
e.g. prefabricated building, beam and column
construction, timber frame construction
Effect
• Slight damping of the outside temperature
• Short excessive increase in flow temperature with
quick heat-up

Adjusted outside temperature
In the default setting any changes in the outside temperature have an
effect after a delay of three hours at the latest on the calculation of the
weather-compensated control.
