H/C changeover relay and fault messages

If, instead of being transmitted over the bus, the H/C changeover signal is to be
made available at a relay output e.g. for switch control of a valve or for 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 heating/cooling system without a "Heating/Cooling changeover" signal
on the KNX bus, the controller continues to use the last received value. If the signal
never existed, then "Heating" is used as the default value.

signal failure
If the "H/C changeover" in a 2-pipe system is configured so that it is initiated by
calendar or by operating mode selector, and a changeover signal is received in one
of the zones from another device, then the fault message "> 1 heat/cool
changeover signal" is transmitted.
