Function menu
Constant Pressure menu
The Constant Pressure function maintains a constant pressure in the extract air chamber (only in the pressure transmitter model Vallox Exxeo DPC). You can choose two limit values for the extract air chamber pressure. The Low value specifies the minimum extract air chamber pressure, and the High value specifies the maximum extract air chamber pressure. If analog control is used (0–10 VDC), the minimum extract air chamber pressure equals 0 VDC and the maximum extract air chamber pressure equals 10 VDC. If digital control is
NOTE

Constant Flow menu
used, the minimum extract air chamber pressure = Ext L is active and the maximum extract air chamber pressure = Ext H is active.
The Constant Flow function maintains a extract air flow (only in the pressure transmitter model Vallox Exxeo DPC). You can choose two limit values for the extract air flow. The Low value specifies the minimum air flow and the High value specifies the maximum air flow. If analog control is used (0–10 VDC), the minimum air flow equals 0 VDC and the maximum air flow equals 10 VDC. If digital control is used, the minimum air flow = Ext L is active and the maximum air flow = Ext H is active.
Using the air flow temperature compensation function requires installing the NTC 1 temperature sensor. The temperature measurement NTC 1 is used to correct the change due to the density of air in the air flow. The K value is a model- specific value of the Vallox Exxeo roof fan. An incorrect K value results in an incorrect air flow measurement result.

Constant Speed menu
The fan can be controlled by 0–10 VDC analog control or by digital control. You can choose two limit values for the fan control. The Low value specifies the minimum fan control percentage and the High value specifies the maximum fan control percentage. If analog control (0–10 VDC) is used, the minimum fan control percentage equals 0 VDC and the maximum fan control percentage equals 10 VDC. If digital control is used, the minimum fan control percentage = Ext L is active and the maximum fan control percentage = Ext H is active. See section 1.5 for the fan control options.
Use the + button to proceed to the fan control menu.

Outdoor air compensation menu (NTC 2 Temp)
The outdoor air compensation function (NTC 2 installed) can be used to control the fan speed as a function of the outdoor temperature. When the outdoor temperature drops below the temperature set for starting the outdoor air compensation function, the fan starts to decrease the fan speed linearly by the specified percentage, until the end temperature for outdoor air compensation is reached. The fan speed is restricted by a specified percentage when the outdoor air compensation end temperature is reached.
Use the + button to proceed to the outdoor air compensation menu.
Use the Menu button to proceed to the setting mode.
Use the +/– buttons to set the outdoor air temperature compensation function
to On or Off. Press Menu to confirm the setting. Outdoor air compensation

is a dot in the bottom right corner of the display.
Digital and analog control menu (External Control)
If analog control is selected, the external voltage (0–10 VDC) controls the fan according to the Low and High setpoints specified. If digital control is selected, the external digital data controls the fan according to the Low and High setpoints specified. Grounding the connectors Ext L and Ext H controls the fan’s minimum and maximum according to the settings. If digital or analog control is not active, the fan is controlled according to the minimum value setting.
Use the + button to proceed to the External Control menu.
Use the Menu button to proceed to the 0–10 VDC Control mode. 0–10 VDC Control uses the 0–10 VDC input. The Low and High settings specify the control range according to the control mode selected.
Use the Menu button to proceed to the setting mode.
Use the +/– buttons to select On or Off. Press Menu to confirm the setting. If
digital and analog control are Off, Constant Pressure, Constant Flow and fan
control use the minimum setpoint.

The PI control can be used to control the desired air flow or chamber pressure. The P and I factory settings of the fans are shown in the table below. Depending on the control method, the factory settings may need to be amended. The default settings are the factory settings of the air flow control.
P value menu:
- The menu can be used to control the Propotional gain. The higher the P value, the less impact it has on the control. The lower the P value, the more impact it has on the control.
- A theoretically functional P control value is, depending on the control method, approximately 2–5% of the maximum value for the fan air flow or pressure.
I value menu:
- The menu can be used to control the Integrator gain. The higher the I value, the less impact it has on the control, and the exact setpoint may not be reached. The lower the I value, the more impact it has on the control, and a fairly exact setpoint may be reached.
- A theoretically functional I control value is, depending on the control method, approximately 0.5–2% of the maximum value for fan air flow or pressure.
P value adjustment range 1…200, factory setting 20.
I value adjustment range 1…50, factory setting 5.
