• The E-heating parameter is used to set whether the
device is equipped with an electric heater battery (E-
heating Act.) or a water heater battery (E-heating
Deact.). The unit type (KWL HB 250/KWL HB 500) is
set by selecting the parameter 250 or 500. When
the test programme is ended, the mains plug should
be pulled for 10 seconds. The test programme must
be concluded before you can access the next menu
item. After that, proceed with the commissioning
programme (see section 11).
Air curr. setup
• With this parameter, the function of the installed
microphone is checked and the sensitivity is set.
• The "Hi" (high) and "Lo" (low) values indicate the
level for the volume of the air noise generated by the
ventilation device. The greater the difference between
the "Hi" and "Lo" values, the greater the volume. If
the difference between the Hi-Lo value is larger than
the set "Dta" value, the humidification unit will be
activated.
• By reducing the "Dta" value, the sensitivity can be
increased.
• "F1" visualises whether the humidity control is
switched on or, in the case of "F0", switched off.
• In case of an air volume flow under 100 m³/h, the
noise development of the ventilation device may be
too low for you to detect the operation of the
ventilation device.
In this case, the device does not switch on and
humidification does not take place.
• If the noise development is too low, caused by air
volume flows that are too low, a control cable must be
installed and connected between the ventilation
device and the switch input of the humidification unit
(see section 17).
Descaling
• "Descaling On" starts an automatic descaling
programme that runs for around 120 minutes.
• Programme sequence:
1. Draining of the water
2. 5 minute wait while descaling agent is
being filled
3. 40 minutes of descaling while the rotor is turning
4. After that, rinse four times
5. At the end of the programme, the system
automatically switches to the previous operational
status.
The descaling programme may only be executed by
the expert. While the descaling programme is
running, the ventilation device must be shut off
(odour nuisance).
Air heating<
• In the case of Air heating On, the Time Interval
Mixer parameters and the hysteresis of the extract air
sensor of the extract air control are adapted.
