H/C changeover relay and fault status messages

If, instead of being transmitted over the bus, the H/C changeover signal is provided
at a relay output, e.g. for switch control of a valve, or forwarding to a non-
communicating device, the H/C changeover relay can be configured accordingly.
See the notes on connecting the primary controller to the changeover valve.

In a 2-pipe system without H/C changeover signal on the KNX bus, the controller
continues to use the last received value. If the signal never existed, "Heating" is
used as default value.
