Type of thresholds: Manual control only
If the
“
Type of threshold
”
parameter is set as follows, the levels are only activated or deactivated
manually via their communications objects:
Figure 33: Setting
–
Manual control only
This setting disables any automatic control of the steps. The fan levels can therefore only be
controlled via the objects or via the display.
Behaviour at lock
The following settings are available:
•
not active
The lock function is disabled, and no communication object is shown.
•
hold level
The controller holds the current level, and the ventilation control is blocked due to further
control as long the object has the value 1.
•
send a certain level
The controller sets the adjusted level and locks the ventilation control due to further control
as long the object has the value 1.
As soon as the lock function is activated, the
“
Behaviour when unlocking
”
can be set:
•
not active
The controller remains in the former state.
•
send a certain value
The controller sets the adjusted
“L
evel
at lock”
.
•
automatic mode
The controller switches to automatic mode
Note:
This behaviour is not available for "Step switch bit coded" and "Step switch binary
coded" if "Type of thresholds: manual control only" is active.
•
restore the old state
The controller restores the level, which was active before locking.
