1. UNOcentral product descriptions
UNOnext is an indoor air quality monitor. It detects temperature, humidity, and the
concentration of various gases, and has the ability to link with ventilation equipment for
automatic or manual operation according to air quality. The combination of gas sensors varies
with each model. The full-featured model includes sensors for temperature, humidity,
illuminance, carbon dioxide (CO2), carbon monoxide (CO), formaldehyde (HCHO), total volatile
organic compounds (TVOC), ozone (O3), PM10, PM2.5. UNOcentral is the web GUI
management host for UNOnext. UNOcentral can monitor, manage, and control ventilation
equipment for up to 16 UNOnext devices through the RS485 connection communication
between UNOcentral and UNOnext. If the operator cannot easily set up the RS485 connection,
UNOcentral can use the MQTT protocol to receive the monitoring data of the WiFi-enabled
UNOnext (hereinafter referred to as UNOnext WiFi) via the network through the support of the
system integrator and distributor. For the functional differences between multi-models of
UNOnext and UNOnext WiFi after linking with UNOcentral, see Table 1. Note: UNOnext cannot
be controlled by UNOcentral when the communication between UNOnext and
UNOcentral is conducted through MQTT.
UNOcentral provides Globalview and Signage functions. With Globalview, you can view
the statuses of all connected UNOnext devices at the same time: Including connection status,
sensor value, switch and operation mode of linked ventilation equipment. While Signage is for
a single UNOnext’s sensor value display. In terms of management control, UNOcentral provides
the UNOcentral Management Panel to manage UNOcentral; the UNOnext Operation Panel is
used to view and control the detailed information of each UNOnext.
UNOcentral provides UNOnext data warehouse and event alarm functions. For all
UNOnext devices connected to UNOcentral, the sensor values will be stored at a frequency of

6
1 every 6 minutes, and the data can be browsed for any day within 3 years. In addition, if event
alarms are set correctly, UNOcentral will continue to detect abnormal events, such as: If air
quality exceeds standards, UNOnext is abnormal, or the ventilation equipment is abnormal, it
will be sorted and sent to the designated email inbox.
We hope that users can conveniently monitor and manage all important places through
the combination of UNOnext, UNOcentral, and ventilation equipment—in that way, everyone
can enjoy good air quality and a good living environment.

1.1 UNOcentral installation
As long as UNOcentral is connected to a power supply, the system will begin to operate.
Through the HDMI connection on the back of UNOcentral, UNOcentral's screen can be output
to displays with HDMI interfaces, such as computer monitors and TVs. UNOcentral is managed
through a web GUI. Users can remotely manage UNOcentral through the browsers of other
hosts, or directly output UNOcentral to a display and use a USB keyboard and mouse for
management. To use UNOcentral remote management or other network services, it is
recommended to connect the network cable to the LAN1 port on the back of UNOcentral
(The MAC address of LAN1 is provided on the UNOcentral’s label).As shown in Figure 1.
Figure 1 Example of UNOcentral management method (connection via RS485)
1.2 UNOnext connection method (RS485)
If RS485 communication interface is used between UNOcentral and UNOnext, they must
be used Daisy-Chain, and the communication mode is Modbus/RTU protocol. It is
recommended to use 22AWG multi-core shielded twisted pair cable or above to achieve
the best results. The simple wiring instructions is below, please use the RS485 adapter include
in the box (Please plug-in on the COM1 of the UNOcentral).

1.3 UNOnext WiFi connection method (MQTT)
If the owner is unable to set up RS485 cables for UNOcentral and UNOnext due to certain
reasons, UNOcentral can also use the MQTT connection to receive information from UNOnext's
sensors and linked ventilation equipment. The set up requirements are as follows:
Purchase UNOnext WiFi and correctly set WiFi and MQTT parameters.
UNOcentral must be switched to MQTT mode, and the MQTT parameters and UNOnext
information must be correctly set.
Switch Mode: Refer to 2.1.1.1A System Management to switch.

10
MQTT Settings: Refer to 2.1.1.3 MQTT-Link settings (only in MQTT mode) to set
parameters.
UNOnext WiFi Settings: Refer to 2.1.1.4UNOnext WiFi settings (only in MQTT mode)
to set.
This function is an advanced function of UNOcentral and UNOnext. If you need to use it,
please consult your system integrator or distributor for support.
1.4 UNOweb support
UNOcentral also supports browsing from an external network (Internet) via UNOweb to
browse data on a UNOnext connected to UNOcentral. UNOweb is a cloud service provided by
the UNO team that allows users to conveniently browse the sensor data of UNOcentral and
UNOnext WiFi with external network functionality on the external network. It also provides
historical data from different times for download, according to the differences in the capabilities
of UNOcentral and UNOnext WiFi products.
When UNOcentral is installed, if the physical network cable (installation on the LAN1
port recommended) has the ability to transmit externally, then UNOcentral will provide the
data to UNOweb. Users can register a user account on the UNOweb website and add the
UNOcentral device; they can then view the UNOnext data connected to UNOcentral through
the Globalview, Signage, and Chart provided by UNOweb. For the use of UNOweb, see the
UNOweb operation documentation. The UNOweb link: https://isdweb.deltaww.com
Note:
1. UNOweb support limitations for UNOcentral and UNOnext WiFi: Ports 1883/1884 (SSL
Opt.) of the installation site of UNOcentral and UNOnext WiFi are required to be open for
external connection and let UNOcentral and UNOnext WiFi to communicate with the
UNOweb host.

11
2. UNOweb's browsing restrictions: In addition to ports 80/443 (SSL Opt.) used for standard
web page HTTP/HTTPS (SSL Opt.) browsing, UNOweb also uses ports 8883/8884 (SSL Opt.)
for NO_SSL and SSL transmission, respectively. If UNOweb cannot be used normally on the
internal network, it is recommended to check the firewall rules with the network manager
or IT personnel.
2. Web GUI
This chapter will start to describe the web GUI of UNOcentral. If the user uses an input
device (keyboard, mouse) directly in UNOcentral and uses the HDMI interface to output to the
screen, then the user may open the browser and enter http://127.0.0.1:8888 in the address bar
to open the web GUI of UNOcentral. If you are using other hosts for management, you need
to confirm that the management host and UNOcentral can use port 8888 for HTTP
communication. This should be discussed with the IT unit of the operator or user, and it
is recommended to set a fixed IP for UNOcentral; it is also recommended for the network
cable to be connected to the LAN1 port. See Figure 1. Different cases will use Table 3 sample
URL as an example.

In addition, the entry points of the UNOcentral Management Panel and the UNOnext
Operation Panel are marked on Globalview according to Figure 3, which will be explained in the
following chapters.
2.1.1 UNOcentral Management Panel
This chapter will explain the UNOcentral Management Panel. There are slight differences
in the management panel when using a RS485 connection versus a MQTT connection. These
differences will be explained below. As shown in Figure 4, UNOcentral Management Panel in
RS485 mode currently has 6 tabs, namely UNOcentral, UNOnext, BACnet/IP, Schedule, Event,
and Update. As shown in Figure 5, compared to RS485 mode, UNOcentral in MQTT mode differs
in that the UNOnext and Schedule tabs are hidden, while there are two additional tabs: MQTT-
Link and UNOnext WiFi.
