Heating curve, operating mode

Individual settings can be made for each operating mode separately in
every heating curve.
Heating curve
The heating curve set refers to the Heating system selected under the
menu item Heating circuit data > Basic setting. The settings can be
made in a table or a graphic representation ( Chapter 12.3, page 35).
Temperature settings for the operating modes of the Constant heating curve in the Automatic heating mode operating mode:

The following heating curves can be set:
• Constant
• Base Point
• Radiator/Underfloor Heating
• Room
Operating modes
You can set the following operating modes for each heating curve
separately:
• Automatic heating mode
• Automatic setback mode
• Manual heating mode
• Manual setback mode
• Holiday
Explanation
Constant:
Controlling of a swimming pool heating system
or pre-controlling of ventilation circuits if the
heating must always provide the same set flow
temperature, independent of the outside
temperature.
The heating circuit or this function is switched
off.
Selection that determines whether the heating
circuit or a function is to be switched off once a
set outside temperature has been reached.
The heating circuit is switched off when the set
outside temperature is exceeded and switched
back on when it is undercut.
If you tap a shortcut key, the display jumps to
the settings area of the selected operating
mode.
Explanation
Initial temperature of the heating curve.
Reference temperature for the design of the
heating curve.
Flow temperature for operation with Outdoor
Temperature 1.
Flow temperature for operation with Outdoor
Temperature 2.
Setting of the required room temperature:
Limits the influence of the room temperature
(room temperature hook-up) on the flow
temperature set value. The value specifies the
highest possible room temperature setback.
This also applies for rooms which are also
supplied by the heating circuit and where no
remote control units are installed.
Adjustment of the temperature differentials
between the actual and set temperature
This adjustment effects a parallel displacement
of the heating curve.
Note
With the Constant heating system, a remote
control cannot be connected for this heating
circuit.
The heating circuit is switched off
(summer mode) when the setting is Yes.
The heating circuit is switched off from a set
outside temperature.
You can make separate settings for each
operating mode. For the settings of the setback
types, refer to  Chapter 12.1.2, page 33.
Note
The set Flow temperature setpoint 1 is not
undercut. This temperature ensures that the
minimum boiler temperature is maintained.
Setting under: Heating curve > Outdoor
temperature
Requirements for the setting:
• A Remote Control is selected.
• Room heating system is not selected.
Ensure that the remote control is not exposed to
heat (e.g. lamps, TV sets or other heat sources).
This setting is only recommended if no remote
control has been installed inside the living space.
