midity range is specified in which the setpoint value can be changed (
object value
limit
).
Enter, how the setpoint value will be received from the bus. Basically, a new value can
be received, or simply a command to increase or decrease.
A set setpoint value will be retained until a new value or a change is transferred. The
current value is saved, so that it is retained in the event of a power supply failure and
will be available once the power supply is restored.
In "Humidification and dehumidification" control mode, a dead zone is specified so that
a direct changeover switching between humidification and dehumidification can be
avoided.
Humidification starts, when the relative air humidity is lower or equal to the setpoint
value - dead zone value.
Dehumidification and/or humidification
Depending on the control mode, settings sections for humidification and dehumidifi-
cation appear (level 1/2).
For dual-level dehumidification, the setpoint value difference between the two levels
must be defined, i.e. the setpoint value which, when exceeded, triggers the switch to
the 2nd level.
Determine the deviation from the setpoint value at which the maximum variable value
is reached, i.e. the point at which maximum output is used.
The reset time shows how quickly the controller responds to deviations from the set-
point value. In case of a short reset time, the control responds with a fast increase of
the control variable. In case of a long reset time, the control responds somewhat less
