Parameter setting
Sensor KNX AQS/TH-B-UP
• as of software 3.1 • Version: 01.03.2017 • Technical changes and errors excepted.
Target value setting using parameter:
Set the target value directly.
In "Humidification and dehumidification" control mode, a dead zone is specified so that
no direct changeover switching between humidification and dehumidification is possi-
ble.
Humidification starts when the relative air humidity is lower or equal to the target value
- dead zone value.
Setting a target value via communications object:
Enter how the target value will be received from the bus in advance. Basically, a new
value can be received, or simply a command to increase or decrease.
During initial commissioning, a target value must be provided which will be valid until
the 1st communication of a new target value. For units which have already been taken
into service, the last communicated target value can be used. Basically, an air humidity
range is given in which the target value can be changed (object value limit).
A set target value will be retained until a new value or a change is transferred. The cur-
rent value is saved in EEPROM, so that this is retained in the event of a power supply
failure and will be available once the power supply is restored.
Dehumidification and/or humidification
Depending on the control mode, settings sections for humidification and dehumidifi-
cation will appear (stage 1/2).
