the forced-draught burner. The microprocessor-

is logged, and the information can be reconstructed
on control unit
on startup of the system - even if there has been a
power failure in the meantime. In the event of a
malfunction occurring, the LED indicator in the
"Reset" button (R) lights up and stays permanently
lit until the fault has been acknowledged (i.e. until
the error has been cleared or the control unit fault
has been dealt with).
The light pauses every ten seconds to emit a
blink-code designed to indicate the cause of the
malfunction. It is possible, using the display
program (available as an accessory), to obtain
further in-depth information on the system's
operating and malfunction procedures.
Locking and unlocking the system
The automatic unit can be locked (corresponding to
a malfunction) and unlocked (cleared) by pressing
the "Reset" button (R), provided the system is
connected to the power supply. If the button is
pressed during normal or startup mode, the device
goes into malfunction mode. If the button is
pressed with the system in malfunction mode, the
automatic unit is unblocked.
m
Always disconnect the power supply before
installing or removing the automatic unit. DO
NOT attempt to open the automatic unit, as
there are no user-serviceable parts inside.
