The Chimney sweep function is automatically deactivated when the boiler temperature
reaches the switch-off point.
Note!
If dynamic switching limits are activated (Dyn SD on setpoint (2464), Min setpoint
change dyn SD (2465), Dyn SD with HC/DHW change (2466) and Dyn SD when
burner on (2467)), they also apply to the Chimney sweep function .
The burner’s output during the time the Chimney sweep function is active can be set:
 Low-fire: Chimney sweep function with minimum boiler output
 High-fire: Chimney sweep function with maximum boiler output
 Maximum heating load: Chimney sweep function with parameterized maximum
boiler output
Note!
When pressing the manual control button during the time the Chimney sweep
function is active, the function is aborted and a change to manual control is made.
The function is automatically aborted after a timeout of 1 hour, provided the switch-off
point for automatic shutdown is not reached during that period of time.
