Operation instructions controller
Power-down time
The power-down time is factory set. In contrast to the power-up time, this is the time required for the motor to
get from maximum speed to zero. Again, the aim is to protect the mechanical components. This value is preset
at 10 seconds. Adjustment range: 1-30 s. Changes can cause damage to the humidifier.
Line pressure fault message
If several appliances are using the osmosis system and are running simultaneously, the line pressure can drop
below 1.6 bar. This causes the humidifier to stop or switch off. In this menu item, the tripping time of the line
pressure fault message can be extended (up to 30 minutes) or the fault message can even be switched off (Fault
message off). This means that the humidifier is on standby for longer or all the time, when the line pressure is
above 2 bar.

Rinse type
The type of hygienic rinse is set depending on the model. For normal rinsing, forward water pressure will rinse the
conduit, filter, pump and nozzles with fresh water. If oil-free pressured air is available, air rinse is preferable. In this
hygienic rinse there are 3 steps. First the conduits are rinsed with fresh water. In the second step the filter is cleared
using pressured air, and in the third step the nozzles are also cleared with pressured air. This complete clearing
of the humidifier’s system can exclude bacterial contamination due to standing water. An optional pressured air
compressor can be integrated into the pumping station.
Rinse interval
For hygienic operation of the humidifier, the controller has two different kinds of rinses serial-
ly integrated. The factory setting for the rinse interval is preset to 48 hours (values can be set between 1
and 96 hours). This is the time between two rinse procedures. A rinse is activated when the humidifier re-
ceives no request via the control signal or connected humidity sensor, over the duration of the set rinse interval.
Caution: The hygienic rinses are also active without a specified permission. Mains power must always be connected.
