Checking the usage
Burner control unit BCU 570 is designed to moni-
tor and control modulating forced draught burners
of unlimited capacity in intermittent or continuous
operation.
The fail-safe outputs for controlling the burners, e.g.
for fan, actuator and valves, are activated via a re-
placeable power module. All the parameters required
for operation are saved on the integrated parameter
chip card.
