3 Environment Ambient Temperature The L642 is designed for ambient operating temperatures between -20°C to 50°C (4°F to 122°F). It is necessary to verify the environmental temperature. Make sure to install the housing at a safe distance of any nearby heating sources. Note that too cold water can cause condensation, which can lead to damage in the device, the ambient operating relative humidity is between 10-100% RH(non- condensing).
Stability: The L642 device is able to recover from network failures. However, if a network is down for a longer time, data might get dropped. The L642 buffers all data for at least 30 seconds. This data can retroactively be retrieved.
If you want to configure the L642 to connect it in mode 3 or 4, you will first need to connect it in mode 1 or 2 and change the configuration of the L642 via the dashboard as explained in section 4.3.
