"Chimney sweep" button
The "Chimney sweep" button (fig. 5,
item 3
) is used to
put the boiler into manual operation mode, e.g. if the
heating system control (e.g. room controller) is defec-
tive.
The heating system can be operated in manual mode,
independent of a room controller on a temporary basis.
The control system must comply with Part L1 + L2.
In this case, the CH (boiler) flow temperature setting of
the right-hand dial is used as the temperature for boiler
operation. See table 6 "Manual Operation menu".
"Service" button
The "Service" button (fig. 5,
item 4
) is used to display
the current CH (boiler) flow temperature, the current
working pressure etc. Also see section 6.1.1, page 18.
Service Connector
The heating engineer can connect a Service Tool here
(fig. 5,
item 5
) for diagnostic purposes when servicing.
"Burner" (On/Off) LED
The "Burner" (On/Off) LED (fig. 5,
item 6
) lights up when
the burner of the boiler is switched on and it is extin-
guished when the burner is switched off.
The "Burner" (On/Off) LED indicates the burner status.
"Heat demand" LED
The "Heat demand" LED (fig. 5,
item 7
) lights up when
the control system has made a heat demand and it is
extinguished when this heat demand is no longer
required.

DAMAGE TO THE INSTALLATION
due to freezing while manual operation is
switched on.
After a power failure or after switching off the
supply voltage, the heating system may
freeze since manual operation is no longer
active.
Re-activate manual operation after
switching on the heating system, so that
the system is permanently in operation
(especially if there is a risk of freezing).
