Flow control
If a function is to be controlled by flow, the flow
control must be switched on (Fc = flow control). In
the Fig. 16, the flow control is activated ("on").

Speed control for the circulation pump
If a function is to be controlled by speed, the speed
of the circulation pump must be set.

Function descriptions
The tables in this section describe the key variables of the functions as follows:
n The rows contain the key variables in the same sequence as they appear on the display.
n The columns contain the following information from left to right:
Column Description
Display Example for the display when setting the key variables.
Key variable Descriptions of the key variables and their dependencies to each other. Dependent key
variables can only be selected and set of the higher-level key variable has the value
"on". This is displayed as follows:
n Higher-level key variable: Bold font
n Dependent key variables: Below the higher-level key variable and indented to the
right
Example: In the table of the circulation function, the probe input, switch-on temperature
and switch-off temperature key variables are only displayed if the temperature control
has the value "on".
minimum, max-
imum, factory
setting
The lower (minimum) and upper (maximum) limits of the value range of a key variable,
as well as the factory setting. If a value range only contains a few values, these are
specified individually. Example: "on", "oFF".
Heat content
Calculates the heat content determined using the
following key variables:
n Hot water temperature, secondary
n
Cold water temperature, secondary
n Medium flow rate, secondary
No further settings are required. The function can
only be activated or deactivated.
Fig. 18: Calculating heat content
Measured value display: The measured values
are displayed in the status menu. The current per-
formance and the daily heat content are displayed
after the fresh water values.
