system will be automatically created on the desktop. The default username of this system is admin,
password is admin.
When first installed, the page pop-up takes 1 to 2 minutes, please be patient.
Figure3.3 Login screen
3.2 IP address setting
3.2.1 Air-conditioning centralized management server IP address setting
Due to different operating system of air conditioning centralized management server, refer to the
IP address setting instructions of relevant operating system for its IP setting, but the IP address of
the server must be in the same network segment with the IP address of air conditioning adapter.

The so-called same network segment refers to the first 3 segments of the IP address are the
same(subnet mask: 255.255.255.0 is supposed),, for example, the first three segments of
192.168.1.2 and 192.168.1.101 are “192.168.1”, so 192.168.1.101 and 192.168.1.2 are in the same
network segment.
3.2.2 Air-conditioning adapter IP address setting
The factory default IP of air conditioning adapter is set as:
IP address:192.168.1.101
Subnet mask: 255.255.255.0
Default adapter: 192.168.1.1
When used on site, the IP address of the air conditioning adapter is re-set according to network
configuration on the site.
How to set the IP of air conditioning adapter:
1. First, prepare a server for air conditioning adapter IP address setting (laptop of debugging
personnel or air conditioning centralized management server), set “Local IP” address of the server
to:
IP address: 192.168.1.2
Subnet mask:255.255.255.0
Default adapter:192.168.1.1
2. Power on the adapter to be set, waiting for the adapter getting into working state (“RUN”
indicator flashes, without considering other indicators),
3. Connect the server for setting directly to the air-conditioning adapter with a network cable,
enter the IP address of the air-conditioning adapter in the server web browser address bar:
192.168.1.101, press carriage return, the browser displays the login screen as shown in Figure 3.4:
Figure 3.4 Setting and debugging login screen
4. Enter the user name: admin, with no password, click on the login, the interface appears
after login as shown in Figure 3.5.

Figure3.5 Setting and debugging
Click <Network Settings> into the IP settings interface, as shown in Figure 3.6 (other options have
nothing to do with IP address setting, do not change, otherwise it will lead to consequences of
unable to return!)
Figure 3.6 Network Settings screen
5. According to the site conditions, it only needs to change <LAN IP Address> and <Remote
Server IP Address> to change the settings of the IP address, <Remote Server IP Address> is the
server IP address for installing air-conditioning system management software. Click <Change>
button, as shown in Figure 3.7, the system prompts to confirm the information. Click <OK>, the
air conditioning adapter IP address change is completed.
Figure 3.7 Network settings confirmation interface
Note:
※If in need of check settings or re-set, enter the new set IP address in the browser address
bar to enter the setting interface, or it cannot be logged in, for example, if the IP address
is changed from factory setting of 192.168.1.101 to 192.168.1.105, it will display a
prompt of inability to log in when entering 192.168.1.101 in the address bar, you need to
enter the new address 192.168.1.105 to re-enter the adapter setting interface, so after

setting the IP address, the new IP address must be marked on a tag attached to the adapter
to facilitate future maintenance.
※Pay attention to the sequence of this operation, first set the computer’sLocal IP, then
wait until the adapter is in the normal working state (“RUN”indicator flashes, without
considering other indicators), then connect the computer to the air conditioning adapter
with a network cable. Otherwise, if connect the computer to the adapter, then power on
the adapter and set the computer’s Local IP, it may not enter the setting interface.
3.3 Check the air conditioning connection of each adapter
If the air conditioning adapter has been connected with H-NET communication wire, when the
adapter is powered on, it will automatically start searching for the air conditioning connected to it
(in this case the “RUN” indicator is on), after the search is completed, “RUN” indicator starts
flashing, the adapter is in the normal working state, if the “STAT” indicator is on at this time,
indicating that no air conditioning is found, and if flashing, it indicates the adapter has found at
least one air conditioner. Click <Aircondition Management> in the main interface of adapter, enter
the air conditioning management interface, as shown in Figure 3.8:
Figure 3.8 Air conditioning connection information
The interface shows the number of the indoor air conditioners connected and their addresses, as
well as working condition of indoor air conditioners, as shown above, the “red flag”indicates air
conditioning switched on, “Heat” means heating, “26 ℃” indicates set temperature, “0-0”means
air conditioning address. (“Refrigeration System number - address Number”). By pressing “ON”,
“OFF”, “COOL”and other buttons, the air-conditioning can be controlled, “Refresh”button is to
refresh and get the latest state of air conditioning (Note: Only by pressing this button, the latest
status of air conditioner can be obtained)
When "Operate Selected" is selected, you need to check the indoor unit you want to control, and
then press the button you want to control, the indoor unit selected will respond as per the specified
button action.
+
When “Operate All”is selected, press the control button, all indoor units connected to this adapter
will act correspondingly as per the specified button action.

4. Air Conditioner Adapter Power Supply Input
4.1 Power Supply Input
(1) Firstly, confirm that power normal (DC 12V),H-NET and LAN connection is normal,
then supply power to the machine.
(2) When power supply is input, POWER light of adapter is lightened normally (power
supply indicator) and RUN light (operation indicator) is lightened normally until air conditioner
searching is completed when the RUN light will start flickering.
(3) When air conditioner searching is completed, the RUN light will start flickering. If the
adapter fails to search out air conditioner, STAT will be lightened normally. If at least 1 air
conditioner is searched out, the STAT light won’t be lightened.
(4) When the machine works normally, POWER light will be lightened normally, H-NET
light will flicker irregularly and RUN light will flicker regularly.
4.2 Reset to Defaults
When it is electrified and RUN light is lightened normally, it can be reset to defaults in the
first 15 seconds. At this time, when long pressing the Reset Button for 4 seconds, the RUN light
will die out. At this time, if stop pressing the Reset Button, the RUN light will flicker, the STST
light will be lighted normally after 2 seconds, and resetting is completed. When electrify again, the
system will be reset to defaults.
※Conduct air conditioner searching after RUN is lighting for 15 seconds. It is invalid
pressing the RESET button at this time.
※Reset to default will only empty information of timer and air conditioner locking, ip
address will be recovered to 192.168.1.101, and billing related information won’t be emptied.
