Load control in IPerHome
When a prefixed power threshold is exceeded, a first relay is cut-off. After some seconds, if the threshold is still exceeded, the second relay is cut-off. And so on.
The loads to be cut-off can be connected to relays of different modules.
An acoustic alarm can signal the overriding condition.
An alarm memory can show the end user that a cut-off has taken place. Useful when cut-offs occur in the absence of the end user.
