• The Elect. Heating parameter is used to set whether the
device is equipped with an electricheater battery (Elect.
Heating Act.) or a water heater battery (Elect. Heating
Deact.). When thetest program is ended, the mains plug
should be pulled for 10 seconds. The test program must-
be concluded before you can access the next menu item.
After that, proceed with thecommissioning program
(see Chapter 12)
.
• With this parameter, the function of the installed micro-
phone 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 ventila-
tion device. The greater the difference between the „Hi“
and „Lo“ values, the greater the volume.
• By reducing the
„Dta“
value, the sensitivity can be incre-
ased.
• „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 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 Chapter 18).
• „Descaling On“
starts an automatic descaling program
that runs for about 120 minutes.
• For program sequence, see chapter 20.04. “Decalcifi-
cation“
The decalcification program must only be carried out by
a specialist. When the decalcification program is running,
the ventilation unit must be switched off (odour)
• 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.
