INSTRUCTIONS FOR USE

Instructions for using VALLOX DIGIT2 SE

Also get acquainted with the technical specification. It gives a broader description of the
parts and functioning of the unit.
For indoor air to stay healthy and beneficial also for the structures of the dwelling, ventilation
has to be in operation continuously. 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. Connect the plug to the mains supply. VALLOX DIGIT2 SE is now ready for operation.
2.  Turn the unit on and choose a suitable ventilation power at the control panel. There

are either one or more control panels. See the instructions for using the control panel
in Sections 3.2.1. and 3.2.2. A wireless remote control may also be in use.

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/or humidity sensors have been installed in the
system, VALLOX DIGIT2 SE 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, with a wireless
controller (option) or with a LON converter (option).
The standard week clock control can be used to control the fan power of the unit and the
setpoint for supply air temperature. (This function is not available in the wireless remote control.)
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 control panel can be used for the following ventilation control functions:

2.3.1.  Functions for adjusting ventilation power

•  Starting and stopping.
•  Power adjustment (8 positions).
•  Setting the base fan speed and the maximum fan speed. Ventilation power cannot be set

lower than the base fan speed. When carbon dioxide and/or relative humidity
adjustments are activated, power cannot be adjusted higher than the maximum fan
speed. When humidity and carbon dioxide adjustments have been switched off, fan
speed can be raised to speed 8 (if the limitation only exists with adjustments, see the
Settings menu, Section 3.3.6).

2.3.2.  Supply air temperature adjustment functions

•  Switching the electric post-heating unit on/off.
•  Setting the desired supply air temperature (+10 

°

C...+30 

°

C).

• Selecting the desired method for controlling supply air temperature

2.3.3. Preheating

• Setting the control temperature for the electric preheating unit (-6 

°

C...+15 

°

C exhaust air).

• Changing the setpoints.
There may be three control panels at most. When more than one control panel are used, the
most recent control function is valid.
