From version 1.93 onwards, the CAM (Custom Alarm Module) function is now sensor-specific, allowing you to implement multi stage alarm functions for the same sensor. In the example, a warning e-mail is sent at 28 °C; the monitored server is closed down at 35 °C!.
This technical briefing tells you everything about two and four wire technology when using temperature sensors. The correct way to connect the sensors to the Thermoguard sensorcontroller is also documented.
Beginning with Version 1.96, you can monitor an Object with Thermoguard via the Internet by using a router with support for dynamic IP numbers; e.g. DynDNS., and a sensorcontroller. There is no need for a PC or Laptop on the client side. You only need a telephone line with permanent Internet access; e.g. DSL.
This information shows you, that a missing network connector near to your refrigerator is not a problem. Simply use the 110/230 V electrical wiring and two powerline modules
(e.g. devolo "dLAN") to connect the remote network and your Thermoguard sensorcontroller at the refrigerator.
