• The
E-heating
parameter is used to set whether the de-
vice is equipped with an electric heater battery (E-hea-
ting Act.) or a water heater battery (E-heating Deact.).
The unit type (KWL HB 250/KWL HB 500) is set by selec-
ting the parameter 250 or 500. When the test program-
me is ended, the mains plug should be pulled for 10 se-
conds. The test programme must be concluded before
you can access the next menu item. After that, proceed
with the commissioning programme
(see section
12
)
.
• With this parameter, the function of the installed micro-
phone is checked and the sensitivity is set.
• The
“Hi”
and
“Lo”
values indicate the level for the volu-
me 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 air humi-
dification unit will be activated.
• By reducing the
“Dta”
value, the sensitivity can be incre-
ased.
• “F1”
visualises whether the humidity control is switched
on, or switched off in the case of
“F0”
.
• 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 humidifica-
tion 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 air humidification unit
(see section 18)
.
• “Descaling On”
starts an automatic descaling program-
me that runs for around 120 minutes.
• Programme sequence see section 20.3 “Descaling”
The descaling programme may only be executed by the ex-
pert. While the descaling programme is running, the venti-
lation device must be shut off (odour nuisance).
• 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.
