Action
: When checkbox „On” is activated, the summer-/
wintertime changeover will
take place automatically
. When checkbox „Off” is activated,
the time will not be
automatically adjusted
.
The control behaviour of the
KWL ventilation
unit can be adjusted via unit
configuration
. There are two different configurations:
1 = DIBT:
The heat exchanger frost protection is activated at < - 0 °C
outside air
temperature
and ensured by the (optional) preheater or air volume reduction
. In
case of a supply air temperature of
< +5 °C, the fans are switched off.
2 =
PHI: The heat exchanger frost protection is activated at < -3 °C
outside air
temperature
(PHI specification) and
ensured by the preheater stipulated by the
Passivhaus
-Institute. In case of a supply air temperature of < +5 °C,
the fans are
switched off
.
O
ptions: „Plastic”, „Aluminium” or „Enthalpy”
Extract air
: Control voltage of extract/outgoing air fan
Supply air
: Control voltage of supply/outside air fan
The fan stages can be adjusted
via the „System settings” menu (Password

„Continuous
” Humidity control active with continuous control logic
Depending on the humidity level
, the fans are continuously regulated (
fan stages
0
-1-2-3-4) between voltage stage 0 and voltage stage 4.
The percentage control is
displayed on the web server page
or on the comfort controller KWL-BEC
(Factory
setting: Continuous)
.
Only the humidity value is transferred to the
humidity control,
the room
temperat
ure is not used for the auxiliary heating control.
Only the room temperature is transferred to the auxiliary heating control, die
humidity values are
not used for the humidity control.
Both the humidity value
and the room temperature are transferred to the
respective controls
.
