Depending on the variant, Kombi-LWUS can measure temperature, humidity, total volatile organic compound (TVOC) concentration, differential pressure, carbon dioxide (CO2) concentration, and particulate matter (PM). Kombi-LWUS uses LoRaWAN for communication with the cloud. Before using the 915 MHz radio, make sure it is legal in your country. 3 Pictures of variants -RHT-IP42 -RHT-Dust40 -RHT-Dust13 -RHT-DP -RHT 4 5 Installation Mounting Select the installation place so that the air can flow freely on all sides of the transmitter, representing the air that is to be measured. Avoid heat sources and direct sunlight. Place the device to the measuring location with one of the following ways: • Place the Kombi-LWUS on any surface with the bottom facing down. • Mount the wall holder with two universal countersunk screws (ST 2.5 or ST 3.0). Use applicable length depending wall material. In the correct orientation, the wall holder has its hooks pointing upwards. Attach the Kombi-LWUS to the holder. 6 Power supplies The Kombi-LWUS indicates the powerup by blinking the led next to the micro USB socket. -RHT-DP, -RHT, -RHT-IP42 variants These variants are powered with 3 pcs LR6 batteries (AA 1.5 V alkaline). High quality batteries should be used, for example Energizer EN91. The device is supplied with batteries already installed, so it is ready to be used. The Kombi-LWUS can alternatively be powered with an external supply. When an external power supply is used, the batteries can be omitted or used as a backup supply. Use the micro USB socket to connect an external supply into the device. -Dust13, -Dust40, -RHT-CO2-TVOC-Dust40-DP These variants with PM sensor must be powered with an external supply. Use the micro USB socket to connect an external supply into the device. Settings The Kombi-LWUS works with its default settings and no parameter configuration is normally required. However, if it is necessary to change the settings of the device, it can be done with Nokeval’s MekuWin software (available for free at www.nokeval.com). Following procedure should be followed in order to get access to the settings: • Connect a micro-USB cable to the connector and the other end of the cable to a computer. • If Windows requests for a driver, download it at www.nokeval.com > Support, unzip it to a temporary folder, and show that directory as the location for the driver. If there are problems during the installation, try pushing the button every 5-15 seconds or keeping it pressed so that the Kombi-LWUS will not shut down its USB port. • Launch the MekuWin program. • In MekuWin, choose the right COM-port form the Ports-menu. If the port is not visible, try pushing the button on the Kombi-LWUS to wake up the port. • From the Port settings -menu, choose Protocol = ModbusRTU, Address = 1. • Click Direct. • A new window will open for the settings. The configuration menu includes the following settings: • Protection o Describes password protection status “None”, “Locked”, “Unlocked”. • Password input/setup o Unlock protection or change password. See “Protecting the settings” section below for details. • Period o Time between measurements with options from ranging 5 minutes to 6 hours. Default is 15 min. • LoRaWAN o If the Kombi-LWUS is used with the Nokeval cloud platform, the default settings are ok. If you wish to manually set the LoRaWAN credentials and/or integrate it with your cloud platform, see “LoRaWAN settings” and “Uplink payload structure” chapters. 7 Protecting the settings To protect the settings from being easily adjusted, the configuration menu provides a password box. The password can be formed by using up to 16 characters. From the next MekuWin session, the settings cannot be adjusted without knowing…
