1. ELECTRICAL INSTALLATION INSTRUCTIONS
The installation can only be performed by qualied personnel. It is necessary to follow the requirements below
during the installation.
It is recommended to lay the control cables separately from the power
cables, at a minimum distance of 20 cm.
The connector connection is performed strictly according to the wiring
diagram numbering, or with adequate markings (see the principal wiring
diagram of the unit).
When removing the unit parts, do not pull on the connecting wires and
cables!
Before performing any work inside the equipment, make sure that the air
handling is switched off and disconnected from the mains power supply.
1.1. Power supply connection
The unit is designed for a supply voltage of 230 V AC, or 50 Hz; therefore, you must install a socket with an
earthing of the corresponding capacity next to it (see the wiring diagram). The power cable type is indicated in
the wiring diagram.
The unit must be connected to the stationary installation using a 16 A
circuit breaker with 300 mA current leakage protection (type B or B+).
The air handling unit is designed to connect only to a neat outlet, with
protective grounding meeting all the electrical safety requirements.
1.2. Control panel installation
1. The control panel must be installed in the premises under the following conditions:
• at an ambient temperature of 0 °C... 40 °C;
• relative humidity ranging from 20%... 80 %;
• protection from accidentally vertically falling water drops (IP X2).
2. Control panel connection through the hole in the back or in the bottom.
3. The control panel can be mounted on a ush mounting box or in any other place, simply by screwing it to
the surface through the two holes on the fastening surface.
4. The control panel is connected to the controller box. The length of installation cable for the control panel
may not exceed 150 m. The cable type is specied in the principal wiring diagram.

1.4. Temperature sensor installation
The air supply temperature sensor B1 (Fig. 1.4a) must be installed in the air supply duct after cooler section (if
not, then after heater). The minimal distance from the duct connection of the unit up to the sensor be not less
than two circular connection diameters. The water temperature sensor B5 (Fig. 1.4 b.) is mounted on the return
water pipe, by screwing it into the provided hole. The sensor must be thermally insulated!

2. OPERATING MANUAL
2.1. Unit control with the control panel
The air handling unit can be operated by one of the following panels (Fig. 2.1).
C6.1 – panel with a touch screen for parameters of air handling unit setting and indication. The panel has inte-
grated thermometer and hygrometer for indoor climate monitoring.
C6.2 – panel with touch-sensitive buttons is intended for main air handling unit parameters setting.

2.2. Unit operation via a web browser
Not only the control panel, but also a computer can be used to monitor the operation of unit and its components,
as well as changing the settings and activating additional functions. You only have to connect the unit separate
with the network cable, to a computer, local network or Internet.
Procedure for the direct connection to the computer:
1. Plug one end of the cable into the network socket in the controller (see Fig. 1.3 a.), and the other into the
computer.
2. On the computer, in the manual setting box of the computer’s network card, enter the IP address, e.g.,
192.168.0.200 and a subnet mask: 255.255.0.0.
3. Run the Internet browser on the computer and disable the use of all Proxy servers in the settings.
4. In the web browser address bar, enter the default IP address of the air handling unit, 192.168.0.60; but this
can be changed at any time in the panel (in the Advanced Settings menu), and on-line via a web browser
(see the login interface settings).
Tip: Before using, it is recommended to update your web browser to the newest version.
5. If the connection was successful, a window will open where you will have to enter a user name and login
password:
Tip: The user’s login name is “user”. The initial password is also “user”, but the user can later change this to
any other password (see the user interface settings).
Should you forget a changed password, it can be reset to the initial
“user”. To do this, you must restore the factory settings for the air han-
dling unit.

2.3. Unit control with a smartphone
After connecting the air handling unit to a computer network or the Internet, it can be controlled with your
smart phone with an iOS or Android operating system. Download and install the mobile app and, depending on
whether the air handling unit will be available in the internal or external computer network, enter the appropriate
settings (described in more detail in the “Mobile applet installation instructions”).
To download the applet, scan the necessary link, or just search for it in the GooglePlay or iTunes stores.
Tip: The applet user interface and the control capabilities are fully consistent with the C6.1 control.

Main unit parameters: air ow, temperature and lter clogging are displayed in the second window, and the
energy parameters – energy recovery and power consumption – are displayed in the third panel window.
Tip: For window scrolls, swipe your nger on the screen to the appropriate side.
All other air handling unit parameters are presented in the “Overview” menu item (see Section 2.4.6.1.).
1 The air handling unit has the air cooling function, but it requires the following additional components which should be ordered
in advance: DCW duct coil (for water cooling) or DCF duct coil with outdoor DX unit (for DX cooling).
2 For more about the ECO mode, read Section 2.4.4.

2.4.3. Operation mode selection
There is provided four usual operation and four special operation modes. User can choose one of them from
the main panel window by clicking on the center button.

Operation modes
Usual operation modes
Away. The recommended choice when you are not at home or when there are fewer people
inside the premises than usual. The ventilation intensity will be 20%.
Normal. Recommended when there is the usual number of people inside the premises. The
ventilation intensity will be 50%.
Intensive. The recommended choice when there are more people inside the premises than
usual. The ventilation intensity will be 70%.
Boost. The recommended choice when it is necessary to quickly ventilate the premises. The
ventilation will run at its maximum intensity.
Special operation modes
Kitchen. Recommended during cooking, when running the kitchen hood. This mode increases
the efciency of the hood, as the air handling unit will increase the air ow to the premises by up
to 80%, and the discharge is reduced to a minimum intensity of 20%.
Fireplace. The recommended choice when lighting a replace. This mode improves the suction
of the smoke through the chimney, causing a small overpressure in the room, because the unit
supplies fresh air at a 60% intensity and removes the air from the premises at a 50% intensity.
Override. This mode activates the air handling unit at the set intensity of 80%, despite the other
mode settings. This mode has the highest priority over the other modes, and will run even after
the air handling unit has been turned off.
Holidays. The recommended choice when leaving home for a longer period of time. The prem-
ises will be ventilated periodically in 30 min. cycles (several times a day) at the minimum intensity.
Any special operating modes can be activated in the panel and by using a mobile phone or computer. When
you select a special mode, you will need to enter the duration of its operation, after which the air handling unit
will return to the previous mode. KITCHEN, FIREPLACE and OVERRIDE modes are set for time range from
1 to 300 min. In HOLIDAY mode, the time interval can be set from 1 day to 90 days, or a specic date can be
selected.
The KITCHEN, FIREPLACE and OVERRIDE special modes can be ac-
tivated by the external control contacts (Fig. 1.3 b). Modes activation by
the contacts has a priority.
