1. Introduction R718B2 is a Wireless 2-Gang Resistance Temperature Detector for Netvox ClassA type devices based on the LoRaWAN open protocol and is compatible with the LoRaWAN protocol. R718B2 connects two external resistance temperature detectors (PT1000) to measures the temperature. LoRa Wireless Technology: LoRa is a wireless communication technology dedicated to long distance and low power consumption.

4.Set up Instruction On/Off Power on Insert batteries. (users may need a screwdriver to open) Turn on Press and hold the function key for 3 seconds till the green indicator flashes once. Turn off (Restore to factory setting) Press and hold the function key for 5 seconds till green indicator flashes for 20 times. Power off Remove Batteries. 1. Remove and insert the battery; the device is at off state by default.
5. Data Report The device will immediately send a version packet report along with an uplink packet including temperature1, temperature2 and battery voltage. The device sends data in the default configuration before any configuration is done. Default setting: MaxTime : Max Interval = 15 min = 900s MinTime : Min Interval = 15 min = 900s BatteryChange: 0x01 (0.1V) TemperatureChange:0x0064 (10°C) Note: The device report interval will be programmed based on the default firmware which may vary.
Report configuration example: Device Description Device CmdID NetvoxPayLoadData Type ConfigReport MinTime (2bytes Unit:s) 0x01 Req ConfigReport BatteryChange (1byte Unit:0.1v) TemperatureChange (2byte Unit:0.
Example for MinTime/MaxTime logic: Example#1 based on MinTime = 1 Hour, MaxTime= 1 Hour, Reportable Change i.e. BatteryVoltageChange=0.1V MaxTime MaxTime Sleeping(MinTime) Sleeping(MinTime) Wakes up and collects data Wakes up and collects data Wake up and collects data REPORTS 3.6V REPORTS 3.6V REPORTS 3.6V Note: MaxTime=MinTime. Data will only be report according to MaxTime (MinTime) duration regardless BatteryVoltageChange value.
6. Installation This product comes with waterproof function. When using it, the back of it can be adsorbed on the iron surface, or the two ends can be fixed to the wall with screws. 1. The Wireless 2-Gang Resistance Temperature Detector 2. When R718B2 is compared with the last reported (R718B2) has a built-in magnet (see Figure 1 below). When values, the temperature change is exceeded 0.
Note: Please do not disassemble the device unless it is required to replace the batteries. Do not touch the waterproof gasket, LED indicator light, function keys when replacing the batteries. Please use suitable screwdriver to tighten the screws (if using an electric screwdriver, it is recommended to set the torque as 4kgf) to ensure the device is impermeable. 7. Information about Battery Passivation Many of Netvox devices are powered by 3.
8. Important Maintenance Instruction Kindly pay attention to the following in order to achieve the best maintenance of the product: • Keep the device dry. Rain, moisture, or any liquid, might contain minerals and thus corrode electronic circuits. If the device gets wet, please dry it completely. • Do not use or store the device in dusty or dirty environment.
