Air humidification “Off”
The air humidification unit is inhibited manually and can be enabled by
pressing this button.
(yellow)
Air humidification “Standby“
The air humidification unit is in the Standby mode. If the relative humidity
set is lower by more than 5 %, the air humidification unit switches on, if it is
enabled.
(green)
Air humidification “On”
The KWL HBX is in the operating mode, i.e. there is a unit enable and a
system deviation. TheKWL HBX carries out regulation to the air humidity set
and the air temperature set. If the measured air humidity is in a range of
+/- 2 % of the air humidity set, and the water valve merely opens sporadi-
cally within 12 hours, the KWL HBXchanges to standby operation.
Air humidification enabled
Externally: Digital input or Modbus
Internally: Volume flow
Depending on the configuration, a unit enable can either only be effected
via an airflow detection or additionally via a digital enabling contact or
enable via Modbus.
Air humidification not enabled
Externally: Digital input not closed or Modbus
enable inactive
Internally: Volume flow not detected
(green)
Airflow available
The flow sensor integrated at the outlet of the KWL HBX automatically
detects a present air volume flow. This is always a prerequisite for a unit
enable.
