SAFETY

Safe and appropriate handling requires knowledge of the basic safety regulations, and of the intended use of the ventilation system. Read this manual before operating the ventilation unit. Please keep the manual for later reference. If you lose the manual, it can be downloaded from our website. This user manual contains all the information necessary for the safe operation of the system. All persons who operate and maintain the ventilation system must follow the instructions provided in this manual. Furthermore, all local accident prevention regulations must be observed.

NOTE

Installation

Installation and setup should only be carried out by a qualified specialist. Electrical installations and connections must be carried out only by an electrician and in compliance with local regulations.

WARRANTY

The guarantee and liability exclude damage resulting from:

• Inappropriate use of the ventilation system or the control unit
• Incorrect or inappropriate installation, setup, or use
• Neglect of instructions concerning transportation, installation, use, or maintenance
• Structural or electronic modifications or changes made to the software

INTENDED USE

All Vallox air handling units have been designed to provide appropriate and continuous ventilation so as to present no threat to the health of people and to maintain structures in good condition.

IMPORTANT
In order to ensure that the indoor air presents no harm to health and remains optimal also for the structures of the building, ventilation must be kept on without disruptions. It is recommended that ventilation be left turned on during long holidays also. This keeps the indoor air fresh and prevents humidity from condensing in the ventilation ducts and
structures. It also reduces the risk of moisture damage.

WARNING The unit is not intended for use by children under 8 or by persons with reduced sensory, physical or mental capabilities, or whose lack of knowledge and experience does not ensure the safe operation of the unit. Such persons can use the unit under supervision, or by following the instructions of someone who is responsible for their safety. Children must be supervised and not be allowed to play with the device.

DISPOSAL OF THE AIR HANDLING UNIT

Do not dispose of electronic devices with household waste. Follow local laws and regulations on the safe and ecological disposal of the product.

Control panel symbols
The following icons are used in the Vallox Pure Control panel.

VENTILATION SPEED SETTINGS

Ventilation speed is controlled by pressing the fan symbol on the display. The available speed options are slow, fast, and weak clock.
NOTE
The week clock is activated from the week clock menu; the week clock icon is not shown on the main display at other times.

If the running status of the unit deviates from the setting shown on the control panel, the on/off status information icon will appear in the right top corner of the control panel. The on/off status options are:

• Starting up
• Stopping
• Stopped
• The outdoor air efficiency limit restricts the operating speed
• The supply air efficiency limit restricts the operating speed
• The extra time switch controls the speed
• Night cooling controls the speed

FAN SPEEDS

The fan speeds menu enables setting the control method to speed control, pressure control, or air volume control and the running status to either slow or fast, as required by the control method, or setting the maximum boost speed.

NOTE
The fan settings menu shows and enables editing the settings of the selected control method of the fan. The control method is selected from the fan settings and boost menu.

Speed control

Pressure control

IMPORTANT
Pressure control requires external duct pressure sensors.

Air volume control

TEMPERATURES

The Temperaturesmenu is used to set either supply air control or extract air control as the temperature control method and to set the temperature

SETTINGS

The settings menu is used to modify the fan, heating/cooling, frost prevention, and efficiency limit settings and to start a test run.

Fan settings
The Fan settings menu is used to select speed control, pressure control, or air volume control as the control method and to specify the K factors of the fans and the boost settings.
IMPORTANT
K factors must be set based on the type of air handling unit.

K FACTORS

Test run

Start the test run by selecting the Start the test run icon. The test run is started automatically at all speeds (slow, fast, and boost). During the test run, the tested speed is shown on the display and the Start the test run icon is not active.
To cancel an ongoing test run, select Return. When the unit requests a confirmation, select OK. To view the results of the test run, press the Down arrow.
NOTE
The air handling unit must be turned on when the test run is activated. The test run does not turn on the air ventilation unit.
NOTE
Before starting the test run, ensure that the filters and the HR cells are clean.
