NOTICE!
Signals of points 4 and 5 in Fig. 5-15 Page 2 of inputs menu are "logical" signals, not "physi-
cal". The BT320/330 supports either oil or gas operation, but cannot be switched. Therefore
no separate signals for the oil or gas safety interlock chain are generated. The signal on ter-
minal X06 is thus generally known as burner‘s safety interlock chain.
