"Komfovent Home" application connection

All Komfovent air handling unit settings are available through the integrated web site, at the IP address 192.168.0.60, which is set by default at the factory. There are several methods for connection to the controller scheme based on the way of connection.

Connection via browser:

1. Access to the air handling unit parameters directly through the computer, using the Internet browser.

2. Access to the air handling unit parameters in the local area network through the computer, using the Internet browser.

3. Access to the air handling unit parameters on the internet (external network) through the computer, using the Internet browser.

Connect via the Android/iPhone app named Komfovent home:

1. Access to the air handling unit parameters in the local area network through the phone, using the router.

2. Access to the air handling unit parameters online (in the external network) through the phone, using the router.

This instruction contains a brief overview of the connection methods using the Android/iPhone app

1. ACCESS TO THE AIR HANDLING UNIT PARAMETERS IN THE LOCAL AREA NETWORK THROUGH THE PHONE, USING THE ROUTER

It is the simplest way to control the unit from your phone, when you are in the vicinity of the unit. You can only control it by connecting to a local area network router that is connected to the air handling unit. You must have:

1. Air handling unit with controller (C6), controller version 1.140 and above.

2. Mobile phone with Android OS 4.0.0 (GingerBread)/ iPhone and higher, with Komfovent home app.

3. Standard router.

Local area network is the network created by the router from the devices in the local area network for which it has assigned the local area network address. The address is assigned as soon as the device is connected to the router in any way: using a LAN cable or WiFi wireless connection. In this particular case, in the image the mobile phone is connected to the local area network because it is connected to the router wirelessly through WiFi. Therefore, the mobile phone and the air handling unit are in the common Local area network and can interact with each other. It should be emphasized that the local area network has no connection to the internet.

2. CONNECTING THE ROUTER TO THE AIR HANDLING UNIT

1. Connect one end of the LAN cable to the connector of controller in the unit, marked with a special icon 

2. Connect the other end of the LAN cable to one of the several router connections marked with the text “LAN”. Their number is usually 4 or more.

3. CONNECTION TO THE AIR HANDLING UNIT WITH KOMFOVENT HOME APP

(Situation 1 – local area network address in the router’s default settings: 192.168.0.1)

1. Use your phone to connect to the router’s WiFi network to which you have connected the air handling unit.

2. Run the app, if the local area network is located in the xx0.x subnet, the app will immediately connect to the air handling unit.

(Situation 2 – the local area network address is not 192.168.0.x in the factory default settings of the router, but the address is known – for example: 192.168.1.x).

1. Use your phone to connect to the router’s WiFi network to which you have connected the air handling unit.

2. Change the subnet number from the panel at the device. Settings are available by clicking Menu > Settings > Air handling unit > Connectivity. Change the IP address there from 192.168.0.60 to 192.168.1.60.

3. Run the app, because the local area network is located in the subnet xx1.x. The app will attempt to connect to the default factory address, which is 192.168.0.60, but will fail. In such case, in the app, select Menu > Settings > Connectivity > click Add, enter the name of the object you are creating, the new IP address (192.168.1.60), and the PORT number (502), then click ✔. The app will add it to the list.

4. Select an object created from the list and click the Exit arrow, then confirm the changes.

4. CONCEPTS OF EXTERNAL NETWORK AND LOCAL AREA NETWORK

In this case, in the image the mobile phone is connected to the Internet, i.e. the external network, and the router in the local area network has no Internet connection. Therefore, the mobile phone cannot access the air handling unit which is in the router’s local area network.

Important

The type of network you are using – the local or external, depends on the address you are using to connect to the air handling unit. 1. If you are connecting to the unit via WiFi indicating an IP address such as 192.168.0.60 and the Port number 502 – you are on the local area network. (It is not possible to login at this address when you are on the external network). 2. If you connected to the device over the Internet, i.e. by turning on the mobile data or WiFi and have entered the IP address: 84.15.200.253, Port number 4502 – tou are on the external network. In both cases, the result will be the same – you will connect to the air handling unit and can control it. The essential differences between these connections are: in case 2, the data travel path will be very long, although it may be that you are physically close to the device and the router, which may cause connection interruptions and slow down the performance of the app. Meanwhile, in case 1 there will be no communication failures, but you can control the air handling unit only while being within the router’s visibility zone. When you leave, the connection to the air handling unit will be terminated.

 

5. ACCESS TO THE AIR HANDLING UNIT PARAMETERS ONLINE (IN THE EXTERNAL NETWORK) THROUGH THE PHONE, USING THE ROUTER

By connecting the router to the Internet, one can imagine that part of the router is connected to the external network (internet), and the other part is the part that can create another own local area network with its external devices. See Fig.

To prevent the router being lost in the external network, and maintain communication with the router and with other devices in the network, the router must have a unique IP address assigned by your Internet provider. Therefore, let’s assume that the Internet provider has assigned the address to the router – 84.15.200.253. Now, all devices on the external network can access our router at this address, but the local area network created by the router and the devices in it are still out of reach. Meanwhile, devices in the local area network can interact with each other and access the devices on the external network (internet).

(Situation 1 – the phone on the Internet wants to reach the Komfovent air handling unit)

First, create a route in the router (Port forwarding), and indicate in it: the way in which the device from the external network will communicate with the device in the local area network.

This is very simple. Assign the unique Port number to the specific address of the device in the local area network, indicating the protocol type (TCP or UDP).

With this specified data, the router will know what the device from the external network is trying to access and route its data to the device on the local area network.

The Komfovent device communicates with other devices using two Ports: Port 80 with the browser and Port 502 with Komfovent home app, using the TCP protocol type. This is how it looks schematically:

You can create external, i.e. (Start) Port numbers based on your preferences. It is important to remember or write them down. You must specify them for connection to the external devices. Internal (End) Port numbers of devices are usually indicated by the manufacturer, otherwise they should be determined by yourself.

Let’s have a look at what’s going on in the picture above. The phone 1, using the Komfovent home app, wirelessly (GSM/WiFi) connects to the Internet by specifying the router address 84.15.200.253 and the Port number 4502. The router receives the request, and using its settings creates a tunnel for data transfer to the air handling unit with an IP address on the local area network 192.168.0.60 and Port number 502. In this way, the devices on the Internet can connect to, and control the air handling unit.

When connecting through the browser, on the device’s address bar, enter the router address and specify the Port number in the following format: http:// 84.15.200.253:4080. We will access the air handling unit, which is within the router’s local area network.
