for the initial start-up, as the factory settings are always used until the first communi-
cation (setting via objects is ignored).
During initial commissioning, a
setpoint value
must be defined which is valid until
the first communication of a new setpoint value. For units which have already been ta-
ken into service, the last communicated setpoint value can be used. Basically, an air
humidity 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).
