Configuration of The control behaviour of the KWL ventilation unit can be adjusted via unit
ventilation 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.
Options: "Plastic", "Aluminium" or "Enthalpy"
Heat exchanger
type:
Fan stages 1-4: 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: 0103)
under the heading "Fan stages" once the initial start-up is complete
Minimum fan
Options:
stage: Stage 0 = Switch-off function can be activated
Stage 1 = Switch-off function cannot be activated (min. FS 1)
(Factory setting: Stage 1)
Options: Use preheater "On" or "Off"
Preheater:
(Factory setting: On)
HUMIDITY Options: The status of the humidity control can be configured to
"Off", "Stepped" or "Continuous".
CONTROL
"Off" Humidity control deactivated
(only displays if a
"Stepped" Humidity control active with stepped control logic
humidity sensor is
"Continuous" Humidity control active with continuous control logic
connected!)
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).
Required settings
Only humidity: Only the humidity value is transferred to the humidity control, the room
temperature is not used for the auxiliary heating control.
Only temperature: Only the room temperature is transferred to the auxiliary heating control, the
humidity values are not used for the humidity control.
Combined: Both the humidity value and the room temperature are transferred to the
respective controls.
Set value: Adjustable limit value of humidity.
Setting range between 20-80 % RH; step size 5 % RH
(Factory setting: 50 %)
Switching steps: The threshold value in % rel. humidity indicates the value set as the limit value for
the change of rel. humidity. The adjustment is possible in 5 % steps from 5-20 %.
If the set value is exceeded, the next higher stage will be activated until the value
falls below the set value.
