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 dia-
gram numbering, or with adequate markings (see the principal wiring dia-
gram of the unit).
When removing the unit parts, do not pull on the connecting wires and ca-
bles!
Before performing any work inside the equipment, make sure that the air
handling is switched o 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.
It is recommended to connect AHU to the mains via 16 A automatic 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 protec-
tive 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 falling water drops (IP X0).
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.
Do not use any other type or size screws but those that are packed together
for control panel mounting. Wrong screws may damage electronics board.

The cable thicknesses for the panel connection and others are specied in
the wiring diagram!
Remove protective screen tape, before mounting front cover on the control
panel!
1.3. Connection of external elements
The air handling unit has external connection terminals in the control box, inside the air handling unit. They are
used to connect all the external control elements.

C6_20-08 5
The total power of all the external elements, powered from a 24 V voltage,
must not exceed 30 W.
1.4. Temperature sensor installation
Supply air temperature sensor B1 (Fig. 1.4 a) must be installed in the duct of supplied air to the premises, past all
the additional air heating/cooling equipment (if any). It is recommended to install the sensor in the straight segment
of the air duct within the distance of 5 duct diameters in front and after the sensor (Fig. 1.4 c).*
Supply air temperature sensor B1 is not necessary if CAV or DCV airow con-
trol is not enabled (more details in section 2.4.6.5) and internal electrical* or
duct mounted air heater or cooler is not used.
The at part of sensor must be directed perpendicularly to the airow for
sensing element would be well blown.
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 integrated
thermometer and hygrometer for indoor climate monitoring.
C6.2 – panel with touch-sensitive buttons is intended for main air handling unit parameters setting.

Fig. 2.1. Choice of control panels
2.2. Connecting the unit to local computer network or the Internet
The unit can be controlled not only by the control panel, but also by computer. In such cases, the air handling unit
must be connected to a local computer network or to the Internet. The unit is controlled by a computer using a web
browser. The air handling unit is connected to the computer network with a CAT5 type cable (RJ45 connector; see Fig.
1.3 a). The total cable length between the unit and the network router must not exceed 100 m.
The IP address can be found and changed on the control panel*(see Advanced settings→Connectivity).
An air handling unit connected to a network router can be controlled by a computer via a wireless connection
(Wi-Fi) on the local network. After connecting the unit to the network router, activate the DHCP setting on the panel
(see Advanced settings→Connectivity). This will automatically assign the unit a free IP address on the local network
(do not use this setting if you connect the computer directly to the unit).

When connecting the computer directly to the unit, in the network settings of the computer, it is needed to
manually assign an IP address the last number of which would be dierent from the unit’s IP address (for example,
if the unit’s IP address is 192.168.0.60, assign the address 192.168.0.70 to the computer). Also enter the subnet mask:
255.255.0.0.
