Setpoints
The parameter "Setpoint valid" can be used to set when a fixed setpoint is to be valid.
Important: This parameter is only available if "Day/Night switching" has been activated in the
"General settings" menu.
The settings have the following effect:
• for Day (Night deactivated)
With this setting, only one setpoint can be specified for "Day" operation. In "Night" mode, the
control is switched off.
• for Night (Day deactivated)
With this setting, only one setpoint can be specified for "Night" operation. In "Day" mode, the
control is switched off.
• for Day and Night
With this setting, two separate setpoints can be specified for Day and Night operation. In this
way, the PI controller controls in "Day" or "Night" mode to the respective set value.
Reset the preset setpoint to parameter settings via object 37 at the next Day/Night switchover
With object 37 - "Preset setpoint", a new setpoint can be specified via visualisation, etc. Activating
the parameter has the effect that the manual pre-setting of a new setpoint via this object 37
becomes invalid when switching between "Day" and "Night" operation and the parameter value is
reloaded.
In the event of a reset or reprogramming, the configured setpoint always applies.
Minimum/Maximum control value for „Day“/“Night“
With this setting, the control value of the air quality control can be limited. If, for example, the fan is
only to run at 30% in "Night" mode, to keep the noise level of the ventilation low or to avoid
draughts, this can be realised here. Please note that the minimum/maximum values limit the
control and thus the actual value may not be completely controlled up to the setpoint.
If the Day/Night object is activated in the "General Settings" menu, different values can be defined
for "Day" or "Night" operation.
Note: If the "Day/Night" object is not active, the text addition "for Day" or "for Night" is omitted and
only a "Minimum Value" and a "Maximum Value" can be defined.
Proportional value:
The proportional value stands for the P-component of a control. This leads to a proportional
increase of the control value to the control difference.
A small proportional band leads to a fast control of the control difference. With a small proportional
band, the controller reacts almost immediately and sets the control value almost to the maximum
value (100%) even with small control differences. However, if the proportional band is selected too
small, the risk of overshooting is very high.
