The table below shows the fan speed that is adequate for normal basic ventilation in dwellings
of different sizes, if there are no better measurement data available. The table also indicates
the total electricity consumption of the fans in each case.

INSTRUCTIONS FOR USE
2.Instructions for use: VALLOX DIGIT SE
In order for indoor air to remain healthy, also for the structures of thebuilding,
ventilation has to be in continuous operation. Do not stop ventilation even for
longer holidays, because that will make room air musty, and during the heating
period room air humidity may condensate in theducts and the structures, thereby
causing humidity damage. The sensors automatically set ventilation to an optimal
level even if the house is empty.
2.1. Taking into use
1. Connect the plug into the power supply. VALLOX DIGIT SE is now readyfor
operation.
2. Start the unit and select an appropriate ventilation rate on the controlpanel.
The unit includes one or more control panels. For instructions on how to use
them, see Section 3.2.1. and 3.2.2.
In normal conditions, basic ventilation is adequate, which means that air isreplaced
once every two hours. Increased ventilation is neededduring sauna baths, cooking,
washing of clothes or family parties. If CO
2
and humidity sensors have been
installed in the system, VALLOX DIGIT SE will also take 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 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 following ventilation control functions can be performed at the control panel:
Ventilation rate regulation
• Starting and stopping
• Capacity regulation (8 positions).
• Setting the basic fan speed and the maximum fan speed. Ventilation rate cannot be set
lower than the basic fan speed. When CO
2
and/or %RH adjustments are activated,
capacity cannot be adjusted to exceed the maximum fan speed. When CO
2
and %RH
adjustments are not enabled, fan speed can be raised to speed 8.
Supply air temperature control functions
• Switching the electric or water-circulated post-heating unit on or off.
• Setting the desired supply air temperature (+10°C...+30°C).
• Choosing the control mode for desired supply air temperature (constant temperature
control, cascade control).
Preheating
• Setting the control temperature for the preheating unit (-6°C...+15°C exhaust air).
• Changing the setpoints.
Max 3 control panels may be in operation. When two or more control panels are used, the
most recent control function is the one that is valid.
