Chimney sweep function
The burner will be switched on. To achieve continuous burner operation, the only
switch-off point used is the boiler temperature's maximum limitation (TKmax).
First, all connected loads will be locked, enabling the boiler temperature to reach the
setpoint of 64 °C as quickly as possible.
When the minimum temperature of 64 °C is attained, the available heating circuits are
switched on one by one, using a dummy load, to make sure that the heat generated by
the boiler is drawn off so that the burner will remain in operation.
For safety reasons, the maximum boiler temperature limitation (TKmax) remains active
as long as the chimney sweep function is active.
The function is deactivated by setting -.- on this operating line, or automatically after a
timeout of 1 hour.
