INSTRUCTIONS FOR USE
2. Instructions for use
For indoor air to stay healthy and beneficial also for the structures of the dwelling,
ventilation has to be in operation continually. It is not advisable to stop ventilation
even for longer holidays, because it makes indoor air stuffy. Also, during the
heating season indoor air humidity may condense in the ducts and structures
and therefore cause humidity damage. The sensors automatically adjust ventilation
to an optimal level even if the dwelling is empty.
2.1. Making the unit ready for operation
1. After VALLOX 180 has been connected permanently to the mains supply
and the control panel to the unit, it is ready for operation.
2. Turn the unit on and choose a suitable power of ventilation at the control
panel. There are either one or more control panels. See the instructions for
using the control panel in Section 3.2.1.
In normal conditions basic ventilation, with a change of air every two hours,
is sufficient in living areas. Boosting is needed during for example sauna baths,
cooking, clothes washing or family parties. If carbon dioxide and humidity
sensors have been installed in the system, VALLOX 180 also takes care of
demand controlled ventilation.
2.2. Ventilation control
The unit can be fully controlled with the control panel delivered with the unit or
with an optional LON converter.
The standard week clock control can be used to control the fan power of the
unit and the setpoint for supply air temperature.
Furthermore, demand controlled ventilation can be adjusted automatically with optional
carbon dioxide and humidity sensors.
The fan power of the unit can also be controlled with a voltage or current signal.
2.3. Ventilation control with control panel
The control panel can be used for the following ventilation control functions:
Functions for adjusting ventilation power:
• Starting and stopping.
• Power adjustment (8 positions).
• Setting the basic fan speed and the maximum fan speed. Ventilation power cannot be
set lower than the basic fan speed. When carbon dioxide and/or relative humidity
adjustments are activated, power cannot be adjusted higher than the set maximum fan
speed. When humidity and carbon dioxide adjustments are switched off, fan speed can
be raised to position 8 (factory setting). Maximum fan speed limitation can be selected
at the settings menu to be in operation permanently (see the instructions for using the
control panel, Section 3.3.3.).
Supply air temperature adjustment functions (postiheating unit is an option)
• Switching the electric or water-circulating post-heating unit on / off.
• Setting the desired supply air temperature (+10
°
C...+30
°
C).
• Selecting the method for controlling the desired supply air temperature (standard
temperature adjustment, cascade based temperature adjustment).
Preheating
• Setting the control temperature for the preheating unit (–6
°
C...+15
°
C exhaust air).
• Changing the setpoints.
• There may be three control panels at most. When two or more control panels are used,
the most recent control function is valid.
