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.

System data

Settings for the entire heating system can be made in this menu.

Table 10 Settings in the system data menu

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.

Example for adjusted outside temperature:

[1]

Actual outside temperature

[2]

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.

conn

[230V] The mixed additional heater is controlled by on/off
signal.
[0-10V] The mixed additional heater is controlled based
on power demand.

Delay time for
mixer

[0...120] min: Set the delay for opening of the mixing valve
to allow the auxiliary heater to preheat.

Mixer run time

[1...

...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.

1) Not available if Germany is set as country.

[-20...20] °C: The auxiliary heater is allowed to start in
parallel operation below the set outdoor temperature.

Control range: Function description

Is a buffer cylinder
installed?

[Yes] | [No]: Set if a buffer cylinder is installed in the
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
pump

[Heating pump]: the internal heat source pump also serves
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.

Damping

1) To get a more responsive regulation it is recommended to choose “No”.

[

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.
