VALLOX 180 SE
INSTRUCTIONS FOR USE

© VALLOX • We reserve the right to make changes without prior notification.
2.4. Ventilation control with carbon dioxide sensor (option)
• In carbon dioxide control, VALLOX 180 SE adjusts fan speed so as to keep carbon
dioxide content in the ventilation zone below the setpoint. When two or more sensors
are used, fan speed is adjusted according to the highest measuring result.
• It is possible to connect 1...5 carbon dioxide sensors as options to the VALLOX 180 SE
unit.
• The adjustment is switched on / off and, if needed, the setpoint (500...2000 ppm) is set
at the control panel. The factory setting is 900 ppm. The recommended maximum
carbon dioxide content in good indoor air is 1,000 ppm.
• When carbon dioxide control is on, the control panel may be used to raise fan speed to
the maximum fan speed and to decrease it to the basic fan speed. In carbon dioxide
control, maximum fan speed limitation is enabled.
2.5. Ventilation control with humidity sensor (option)
There are two methods for adjusting fan speed.
1
Automatic humidity setting
, which is suitable for controlling humidity in washing facilities, for
instance. The program records current humidity level and selects it as the setpoint, which
it then uses as the target for drying air in a bathroom e.g. after a shower. The setpoint
automatically varies according to season, for instance, and is always at the right level.
This setting is factory selected.
2 Humidity level can also be set
fixed
. The setting can be set at the control panel, within the
range of 1...99 %RH. This can be used in public saunas and swimming pools, for
instance. The program aims at keeping humidity at the setpoint. The setpoint can be
changed if needed.
Adjusting mode is chosen at the controller. Recommended humidity content of good indoor
air is approximately 45%.
• When this control is on, the control panel may be used to raise fan speed to the
maximum fan speed and to decrease it to the basic fan speed.
• In humidity control, fan speed varies between the basic and maximum fan speeds
selected.
• When the unit is first taken into use
with automatic setpoint search enabled
(factory setting),
it
takes 3 to 10 hours for the program to define the value
. During this time, humidity adjustment is
not enabled (because the first value, selected at the factory, is 100%).
• Automatic search is enabled even if humidity control is not selected.
2.6. Ventilation control with voltage or current signal
VALLOX 180 SE fan power can be controlled with a voltage or current signal coming from
remote monitoring.
• The signal can be used to select speeds 0–8. However, the set maximum fan speed
cannot be exceeded if carbon dioxide or humidity adjustment is active, or if maximum
fan speed limitation has been selected in the settings menu to be in operation all the time
(see the instructions for using the control panel in Section 3.3.6).
• The signal changes the basic fan speed.
• The signal does not lock fan speed, i.e. fan speed can be changed at the control panel
within the set limits. Carbon dioxide and humidity adjustment also operate within the set
limits.
2.7. Ventilation control with remote monitoring system (option)
• With an optional LON converter, VALLOX 180 SE can be connected to the remote
monitoring system.
• When
VALLOX 180 SE is connected to the remote monitoring system, compatibility
between the two needs to be ensured.
• The remote monitoring system can control the same functions as the control panel does.
• The remote monitoring system works in parallel with the control panel as well as carbon
dioxide and humidity sensors.
