4.5. Connecting the Unit to the Internal Computer Network or the Internet
Your AHU may be controlled not only with a control panel, but also with a computer or smart phone. For this reason
the unit must be connected to the internal computer network or the Internet. In case of a computer, the unit is controlled
via a web browser, and in case of a smart phone - via the Komfovent app. Use CAT5 type cable to connect your AHU to the
computer network (RJ45 connec
tion; see Fig. 33). The total cable length between the unit and the network router must not
exceed 100 metres. By default, the IP address of your air handling unit is
192.168.0.50
, however it can be changed (if neces-
sary) according to the local network parameters. IP address can be found and changed in the control panel.

Viewing and changing the IP address with a control panel
An air handling unit connected to a network router can be controlled by a computer via wireless connection (Wi-Fi). The
unit may also be controlled wirelessly in a local network using a smart phone with the Komfovent app. Once the unit is con-
nected to the network router, you should assign a free IP address on the local network.
When connecting your computer directly to the unit, open the network settings and manually assign an IP address, the
last number of which would be different from the unit’s IP address (for example, if the unit’s IP address is 192.168.0.50, assign
the address 192.168.0.70 to the computer). Enter the subnet mask: 255.255.0.0.

Computer network settings for direct connection to the unit
In order to control your AHU over the Interne
t, connect it to the network router which has access to the Internet. Follow
the router manual to configure port forwarding to the unit IP address. Depending on whether you will use your computer
or smart phone with the Komfovent app to control your AHU, you will also need to enter a corresponding port number to
the router. For control via your computer use the port
80
, and for control via your smart phone use the port
502
. Once a
computer or smart phone is connected to the Internet, enter an external router IP address and set port number to your web
browser or the Komfovent app to access the AHU user interface (for more information on control with a computer or smart
phone see “User Manual”).
