The bus system transfers the control signals from the
automation system (PLC) to the BCU/BCM for starting,
resetting, controlling the air valve, purging the furnace
or for cooling and heating during operation. In the op-
posite direction, it sends operating status, the level of
the flame signal and the current program status.
Control signals that are relevant for safety, such as the
safety interlocks, purge and HT input, are wired inde-
pendently of the bus communication using separate
cables.
