Detailed Description

1. The power indicator will light up after power is connected. If the power indicator does not light up, please make sure that the power cord is firmly installed.

2. The air quality indicator will turn blue after the device is turned on, which means that it is booting up. After booting is complete, it will change color according to the air quality status, in which green is good, yellow is normal, red is poor, and purple is polluted.

3. UNOnext has built-in multiple sets of sensors, and the values will be displayed in a rotation. If an item exceeds the threshold, it will be displayed on the screen.

4. Keypad functions will change based on software settings; the default is “smart sensor control” If it is set to “smart sensor control”, double-press the button (within 5 seconds) to switch the wind speed and work mode. The default is AutoMode and may be switched into the following modes. If the interval between key presses is more than five seconds, ventilation equipment will be turned on and off. It will enter AutoMode when it is turned on again.
   If it is set to “air quality sensing” mode, the keys will be used as the switch of the air quality indicator (DIP switch No. 8 must also be pushed up)

5. AutoMode will turn ventilation equipment on and off depending 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 (only on the UNO-C07X011 model)
   Diagram| AutoMode menu| Description
   ---|---|---
   | Turbo| If it exceeds the threshold, ventilation equipment will operate at full speed and exchange air until the air quality improves
   | UNOECO| Depending on air quality, the ventilation equipment will automatically switch between differ- ent wind speeds to achieve the three major indicators – silent, power saving, and health

The default equipment activation standard for CO2 is 1,000 ppm, PM2.5 is 28 ug/m3, PM10 is 60ug/m3, which can be adjusted in the APP, but the color of the indicator light is based on the default range

6. Use the APP for Wi-Fi configuration. The APP will provide instructions on operating procedures. Please verify that the controller you purchased is the Wi-Fi version. The Wi-Fi connection indicator will turn on after connecting to Wi-Fi. (only on the UNO-C07X011 model)
7. The controller was calibrated before leaving the factory, and no additional calibration is required. If the controller is affected by the environment at your site, please contact the distributor for manual calibration.
8. This controller has built-in multiple sets of precision sensors. Collision and vibration during transportation may affect its readings. It is recommended to turn it on and install it, and then wait for about one hour until the chamber reaches balance.
9. After the device is turned on, the sensor needs to warm up for 10 seconds or less for PM2.5, PM10, and carbon dioxide, and 5 minutes for formaldehyde, carbon monoxide, ozone, and TVOC.
10. Sensor data is updated every 3 to 6 seconds (depending on the type of sensor)
11. When UNOnext is connected to the central control unit, and the central control unit is in control, and UNOnext will indicate that it is currently in remote control mode.
    Diagram| Pressing Mode| Description
    ---|---|---
    | Remote control| Connect to the central control unit, which will send control commands.
12. Regardless of whether the central control unit sends a control command, the user presses a physical key, or uses the APP for control, UNOnext will perform the last command that was sent
13. If it is used in a place of business and the owner does not want to let users on site turn it on and off or use the APP to control the device, the owner can use a Modbus command to engage the control lock. When the control lock is engaged, local users cannot perform any operations. If the user manually presses the switch, the image below appears, which means that it cannot be operated by local users.
14. Pressing the button in “air quality sensing” mode will turn the air quality indicator on/off. When the power is turned off, the device will remember its last state.
15. CO2 component automatic calibration The CO2 component is a precision instrument. This product was calibrated at the factory before shipping. After a week of continuous operation, it will be automatically calibrated every week. If the component encounters vibration when it is reinstalled in a different place, the data values may drift.

[Note] Follow the instructions below to facilitate the automatic calibration of CO2 components.

• The product needs continuous power supply, so install it in a fixed position
• The indoor environment reaches the level of the outdoor environment for four consecutive hours each week

Wiring diagram – Connecting to the central control unit

The central control unit can read the sensor data of UNOnext and the status of the ventilation equipment via the RS485 physical line and the Modbus RTU protocol Modbus slave signals can be directly connected with the building automation system for parameter design and data acquisition purposes. next acts as a Modbus slave device through pin 8 (RS485 B) and pin 9 (RS485 A) of the UNOnext terminal block. The RS485 Baud rate is 9600bps, the parity is ‘none’, and the default slave address is 0xD0. For detailed settings and data capture fields, see the UNOnext Modbus file The figure above illustrates the traditional Modbus network architecture. The central control unit can be connected to multiple devices in a linear topology. Cables must be terminated at both ends. Each device has a built-in 120Ω terminal resistor. You can use the first pin of the DIP switch to turn the terminal resistor on or off. Except for the terminal device, which must be set to on, every other slave device must be set to off. The default Modbus slave position of each device is 0xD0, and the slave position of each device must not be repeated. In order for the central control unit to receive the correct data, the second to fourth pins of the DIP switch must be used to set the device slave position.

Wiring diagram – Connecting to ventilation equipment (smart sensor

control mode)

Mode 1, Ventilation equipment is controlled through RS485. The wiring diagram is as shown in the figure below. In addition, the 8th pin of the DIP switch must be turned off. The settings are as follows

1. This controller controls ventilation equipment through RS485. If you do not know whether or not the equipment brand and model is supported, please contact the dealer for technical support before purchase.
2. If, after evaluating the site’s environment, ventilation equipment cannot operate at full speed due to certain reasons (excessive noise or vibration, etc.), the maximum wind speed can be set by adjusting the DIP switch. There are three stages that can be set through the 6th and 7th pins of the DIP switch.

Mode 2, Control the three-speed ventilation equipment through a relay This controller supports relay output. This controller can control 12V or 24V DC relays through the relay, which can be triggered at low level, and the load of the relay should be based on the specifications of the connected ventilation equipment.

Mode 3, Control single speed ventilation equipment through relay This controller supports relay output. The controller can control a 12V or 24V DC relay through the relay, which can be triggered at a low level. The load of the relay should be based on the specifications of the connected ventilation equipment.

Wiring diagram – Installing the external temperature sensor cable

(optional)

The product’s built-in temperature sensor module has an accuracy of +/- 1°C. If you need more precise temperature sensing, the product can be equipped with temperature sensor cable accessories, allowing for accuracy of about +/- 0.3°C, which can meet more precise environment temperature control requirements. After installation, the default temperature display on the screen will be replaced with the temperature detected by the external temperature sensor cable
