Overview

Note : Internal only. NOT for common user.
UNO IAQ app engineer mode is a tool to configure UNOnext/UNOlite. The functions include changing the default setting, doing calibration and others. In this document, we will use the Android UNO IAQ to demonstrate each functions.
The minimal required version for UNO IAQ app as below:

The current model of UNOnext :

Product Number| BLE| Wi- Fi| Temp. Humid.| PM2.5 PM10| CO 2| Lux| TVOC| HCHO| CO| O 3
---|---|---|---|---|---|---|---|---|---|---
UNO-6SR| | | | | | | | | |
UNO-7TR| | | | | | | **| | |
UNO-6SW| **| | | | | **| | | |
UNO-9SW| **| | | | | | | | |
UNO-7HW| | | | | | | | **| |
UNO-10SW| **| | | | | | | | |

UNO-L| | | | | | | **| | |
UNO-LW| **| | | | | | | ****| |

Note :
Please notice if the UNOnext is non-BLE/Wi-Fi model (i.e. UNO-6SR/UNO7TR), you can’t use ENG APP to configure it.
However, you still can upgrade the device firmware through recovery mode.
Refer to the “Device Firmware Upgrade-Recovery Mode” section for more details.

【iPhone User】
Although we only demonstrate the example on UNO IAQ app eng mode in Android app, all functions also can be found on iOS app. However, you need to set the “DELTA ELECTRONICS, INC.” to be the trusted developer before running the engineering APP. The steps are listed below:

1. Install the UNO IAQ app from the private link. You should get it from your vendor.
2. Into the Settings page and click General.
3. Click “DELTA ELECTROINCS,INC.”
4. Click “Trust DELTA ELECTROINCS,INC.”

【Getting Started】
We use an actual example to explain the UNO IAQ app (android 1.2.09 or later, iOS 1.4.11 or later) features in this document.
Let’s start now.
Step 1 : Enable ENG mode
Install the UNO IAQ app from the Playstore or App Store, quick tap the red circle more than 5 times, there will a toast message tell user ENG mode is started;

Step 2 : Select the UNO device
The UNOnext/UNOlite should be found in the list. If not, press the “cycle” button to rescan device.

Step 3 : Into the device configuration page.

Step 4 : The device configuration page
The page list the supported features you can config- ure UNOnext/UNOlite. All items will be described in later section.

Device Configure Page

【A. Firmware Version】
These items show the firmware version of the components in UNOnext. The version format is: major_version.minor_version.build
The items as below:

1. FW Version : The FW version of UNOnext.
2. Sensor Version : The FW version of sensor sub-board.
3. Wi-Fi Version : The FW version of Wi-Fi

【B. Calibration】
You can do sensor calibration manually through eng mode. (CO2 , temperature, PM, IAQLED)

【B.1 CO2】
You can overwrite the UNOnext CO2 measurement through this item. The calibration will work after a few seconds. Please notice the CO2 autocalibration feature still works after doing calibration manually. The legal CO2 calibration range is from 400 ppm to 2000 ppm

【B.2 TEMP】
You can overwrite the UNOnext/UNOlite temperature value here.
After setting the degree, press “CALIBRATION” to write the current temperature to UNOnext/ UNOlite.
There is a legal range for temperature calibration. The range will be shown on dialog and the value is variation based on actual measured temperature.
Please notice that UNOnext/UNOlite doesn’t allow a big gap between the calibration value and the measured one.
You can also press “RESET” button to recover the default value calibrated in factory.

And your manual setting will be lost.

IMPORTANT NOTICE :
Before performing temperature calibration, please make sure the device has already been powered up at least 30 minutes.
【C. MQTT】
You can change the MQTT setting through this item. If you need to receive the MQTT data from UNOnext/UNOlite, you need to modify the UNOnext/UNOLite’s default MQTT broker. Then you can receive data from the specific MQTT broker. You also can change the UNOnext/UNOlite mqtt data format to Flatten or Nested mode.

If the MQTT’s broker was changed, the URL value in this page also will be changed after a few seconds. You can stay in this page to ensure the modification is workable. Refer to another document “UNOnext MQTT user guide” for more information.

IMPORTANT NOTICE :
If the UNOnext/UNOlite need to connect to UNOcentral, please make sure the “Data struct” is selected to “Nested mode”

【D. Reset baud rate】
UNOnext/UNOlite’s Modbus baudrate can be changed from command. This item will clean the baudrate modification and set the it to default val-

【E. Control Mode】
If the UNOnext need to control ventilation fan, the control mode should be enabled. You can use this item to switch the function. The state in the line end is the current state. Press this line to switch the state. Please notice the state changing will let UNOnext reboot. You need to wait 5~6 seconds for UNOnext’s reconnection.
You can check the OLED monitor to ensure if the state is changed.

【F. Temperature unit】
You can change the temperature degree that is displayed in OLED monitor by this item. UNOnext support Celsius or Fahrenheit. Please notice this setting only for UNOnext’s OLED panel but not UNO IAQ app.

【G. ERV filter】
If the control mode is enabled, the ventilation fan’s filter count will be calculated automatically to check whether the filter need to renew. Press this item can clean the counter from start.
You need to use this item if the ventilation fan’s filter was renewed.

【H. Firmware Upgrade】
There are three kinds of firmware in UNOnext : device firmware, sensor firmware and Wi-Fi firmware. Besides, UNOnext has the recovery mode to force update device firmware. Check the following sections for more information.

【H.1 Wi-Fi firmware upgrade】
Follow the steps to do Wi-Fi firmware upgrade:

1. Make sure the UNOnext/UNOlite has been connected to internet.
2. Press the “Wi-Fi firmware upgrade”
3. Wait 10 seconds
4. Check if the “Wifi Version” has been update to the newest one.

IMPORTANT NOTICE :
Do NOT power off UNOnext/UNOlite when firmware

【H.2 Sensor firmware Upgrade】
Follow the steps to upgrade sensor firmware:

1. Got the sensor firmware file from vendor. The file name should be: UNOSNR_vX_XX_XX.bin

2. Press the “Sensor firmware upgrade” button and select the right binary file.

3. ENG mode start to transfer firmware to UNOnext/ UNOlite. The LEDs will keep blinking until sensor firmware upgrading successfully.
   The whole process may take 5~7 minutes.

4. Check if the sensor version has been updated to the newest one.

【H.3 Device firmware upgrade】
Follow the steps to do Device firmware upgrade:

1. Get the device firmware from vendor. The file name should be UNOFL_vX.XX.XX_bxx_app.zip
2. Press the “Device firmware upgrade” and select your UNOnext/UNOlite’s model name.
3. ENG mode will show a dialog to introduce you which firmware should be adopted.
4. Choose the firmware file
5. Press upgrade and wait 1 minutes
6. Check if the firmware version has been updated to the newest

IMPORTANT NOTICE :
Do NOT power off UNOnext/UNOlite or close ENG APP

【Device firmware upgrade – Recovery Mode】

This section describes how to flash device firmware through recovery mode.
You should use recovery mode to flash UNOnext/UNOlite firmware ONLY IF:

1. UNOnext without RF function. The model name is ending with the character “R” (EX: UNO-6SR/UNO-7TR).
2. The device firmware was failed to upgraded before. And you can’t find the device in ENG mode after power cycle UNOnext/UNOLite several times.

Follow the steps below to upgrade device firmware in recovery mode:

1. Use a paperclip or a needle to press the function hole in the back of UNOnex- t/UNOLite. After that, power on device.
2. Open the ENG mode and find a device with the name “Boot mode”, and press” Refresh” button on the top. Then into device configured page and select the corresponding model to flash firmware.

IMPORTANT NOTICE :
Do NOT power off UNOnext/UNOlite or close app when firmware upgrading

Appendix : Direct bind device

If the UNO IAQ app has enable ENG mode, the device can be bound without press button on the UNOnext/UNOlite device.
