Overview
UNOnext is an all-in-one air quality monitor that can detect temperature, humidity, carbon
dioxide, PM2.5, PM10, total volatile organic compounds (VOCs), formaldehyde, carbon
monoxide, and ozone, which can all be monitored visually through sensors. It can be directly
connected to a fresh air system to improve air quality, which not only saves energy, but also
lets users breathe fresh air with peace of mind. It is suitable for many different types of
environments, including residential buildings, commercial buildings, medical institutions, and
places sensitive to air quality, such as nursing homes and day carecenters. This product
detects various types of air pollution that may have an adverse effect on the human body.

Detailed description
‧The power indicator lights up after power is connected. If the power indicator
does not light up, please make sure that the power cord is firmly installed.
‧The air quality indicator turns blue after the device is turned on, which means that
it is booting up. After booting is complete, it changes color according to the air
quality status, in which green is good, yellow is moderate, red is bad, and purple
is polluted.
‧The product has built-in multiple sensors, and the values are displayed in rotation.
If the value of a sensor exceeds the threshold, the warning icon is been displayed
in the upper left of the screen.
‧In “smart control”. double-press the button (within 5 seconds) to change the fan
speed and control mode. The default is “IAQ sensing” and may be switched into
the following modes. If the intervalbetween key presses is more than five
seconds, the equipment is turned on and off. It will enter “smart control” when it is
turned on again. In "IAQ sensing", the button can turn on/off night mode (the
screen and indicators on/off).
Smart control IAQ sensing
‧Use the APP for Wi-Fi configuration. The APP provides instructionson operating
procedures. Please verify that the controller you purchased is the Wi-Fi version.
The Wi-Fi connection indicator turns on after connecting to Wi-Fi.
‧The product was calibrated in the factory, and no additional calibration is
required. If a sensor value is affected by the environment at your site, please
contact the distributor for manual calibration.
‧This controller has built-in multiple sets of precision sensors. Collision and vibration
during transportation may affect its readings. It is recommended that you turn it on
and install it, and then wait for about one hour until the chamber reaches balance.
‧After you turn on the device, these sensors needs to warm-up for 5 minute or
less for PM2.5, PM10, and carbon dioxide, and 5 minutes for formaldehyde,
carbon monoxide, ozone, and TVOC. Sensor data is updated every 10 seconds.
‧The CO2sensor uses an Automatic Baseline Calibration (ABC) algorithm to
maintain accuracy. If the component encountersvibration when it is reinstalled in a
different place, values may drift. Please keep operation for weeks to find the
baseline in this case.
Note Follow the instructions below to facilitate the automatic calibration of CO2
components.
‧This product needs a continuous power supply, please install it in a fixed position
‧The indoor environment reaches the level of the outdoor environment for four
consecutive hours each week

"Smart mode" will turn ventilation equipment on and off depending on whether the air
quality exceeds the threshold or not. There are two control modes: Turbo and
UNOECO. Users can set a threshold on the APP to determine activation
conditions.

Note The default activation standard for CO2is 1,000 ppm, PM2.5 is 28 ug/m3,
PM10 is 60 ug/m3,which can be selected in the APP. The color of the indicator
breathing light is pre-defined by it.
Note The temperature module built into this product has been calibrated in
the factory, but the accuracy may be impacted by the installation environment,
such as nearness to a heat source or high air flow. To get more accuracy,
calibrate the product after installation. Wait for one hour after installation for
calibration. Please contact dealers and local sales for detailed information.

Power onverification
‧After the product has been installed, the power indicator lights up after the power is
connected, and the air quality indicator turns blue, which means the device is
turning on at this time. If green or yellow appears, it means that the device has
completed booting and the current air quality status is displayed. If the power
indicator does not light up, please verify that the power cord is properly connected
and that there is a supply of power.
Do not inject contaminants
Do not directly inject contaminants containing gases or particulate matter.
Exposure to excessive contaminants can permanently damage the sensor.
Do not repair this product yourself
The product does not have components that users can repair themselves. Do not
attempt to open it. Once the warrantysticker breaks, the warranty is void.
【Note】Do not insert objects through the vents, which may be
dangerous and damaging.
Prohibit live line operation
When the installer configures DIP switches and terminal connector, be sure to
power off before execution and then power on after.
‧In RS485 control mode, if the equipment is successfully connected, the
equipment status indicator is static on/off or it will keep blinking.
‧The installer can verify ventilation volume by switching to manual mode with fixed
fan speed.
‧After a period, the health of the filter will return to zero. At this time, it is recommended
to replace the filter. After the replacement, you can press and hold the factory reset
button on the back of the product toreset.

Layout Considerations
For any Delta’s indoor air quality monitors, we recommend an area coverage of 160 m2
with the area of enclosed space calculated individually.
For example:
‧One open space of 160 m2requires one monitor.
‧Three conference rooms of 80 m2each requires three monitors, one in each room.
Space over 160 m2should consider installing multiple monitors throughout the room to
achieve optimal coverage. It is also recommended to align the sensor deployment area
with the HVAC thermal zoning plan.
Located at least ~5 meters (16 feet) away from operable windows, doors and diffusers.
【Installation steps】
1. Use the wall mount included in the box to install it on the wall, or install in a power
box. The wall mount has screw hole spacing (60mm and 84mm)
2. suitable for power boxes in multiple countries, but the power box must be installed
horizontally as shown in Fig.1.
3. Verify that the power supply and data lines are laid out according to specifications
before installation.
4. As shown in Fig.2, installation the wall mount and verify that all four buckles are
installed and fixed.
5. As shown in Fig.3, use a hexagonal screw driver to fasten the M4 hex socket screws to
complete the installation.
Note Power source notice
This product uses a 9-24V DC power supply. AC power must be
converted to the required power source or use the specified power
adapter .
