【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 residentialbuildings, 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.
【Display and button functions】
Appearance Displaylayout
Function definition
Theproduct has two functions which are “smart control” and “IAQ sensing", default is "IAQ sensing".
【Detailed description】
‧The power indicator lights up after power is connected. If the power indicatordoes 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 interval between key
presses is more than five seconds, the equipment is turned on and off. It willenter “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 instructions on 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 additionalcalibration 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 encounters vibration 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 CO2components.
‧This product needs a continuous power supply, please installit in a fixed position
‧Theindoor 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 60ug/m3,
which can be selected in the APP. The color of the indicator breathing light is pre-defined by it.

【Layout Considerations】
【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.

Description
Turbo If it exceeds the threshold, the equipment will operate at full speed and
exchange air until the air quality improves.
UNOECO It’s smart and balanced control strategy by using self-learning from historical
IAQ trend, it will turn the equipment on earlier and try to keep IAQ index under
the threshold.
For any Delta’s indoor air quality monitors, we recommend an area coverage of 160 m2with 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.

【Wiring diagram –Connect the equipment via RS485】
Connect A1 and B1 with the equipment’s A and B, the recommended wire to use is 22AWG Shielded Foil

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
indicatordoes not light up, pleaseverify that the power cord is properly connected and that there is a
supply of power.
‧Wireless model has Bluetooth and Wi-Fi functionality. Users can go to the iPhone app store or Android play
store to download the APP.
【Installation guide】
Installation steps
‧The product is recommended to be installed at a height of 80-150 cm (31.5-59 inches).
‧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) suitable for power boxes in multiple countries, but the power box
must be installed horizontally as shown in Figure 1.

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
warranty sticker breaks, the warranty is void.
【Note】Do not insert objects through the vents, which may be dangerous and damaging.
Cleaning the exterior of UNOnext
To clean the product, unplug the power cord and all wiring.
Wipe with a soft, cotton-free cloth. Avoid moisture at any openingson the device body. Please do not spray
liquids directly onto it.
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 . If it is not correctly connected, the equipment status indicator will keep blinking.
‧The installer can verify ventilation volume by switching to manual mode and corresponding 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 filter reset button on the back of the product toreset.

【Wiring diagram –Connect the equipment via digital output】
【Note】
To connect multiple equipment, you must set different Modbus slave address. Please reference the
user manual of that equipment to config slave address.
Connect multiple equipment
‧The product can connect to the 4 same equipment via RS485 in series through daisy chain - linear
topology. At this time, each device will follow the same control mode and fan speed level.
