CAUTION:
▶ Limit the space heating water temperature to the
maximum flow temperature of the floor heating
circuit.
▶ A power interruption discontinues manual
operation. Frost damage may occur.
"Chimney sweep" button ( fig. 50, [3])
The "Chimney sweep" button is used to put the boiler into flue gas test,
service or manual operation mode. The BC10 maximum heating water
temperature setting applies.
• The flue gas test enables the boiler to be run in full-load operation
manually for a short period ( table 12, page 31).
• The service mode enables the boiler to be run in part-load operation
manually for a short period. Measurements and settings can be
carried out on the boiler ( table 13, page 31).
• The manual operation mode enables the boiler to be operated
manually for a longer period. Use this mode when the control system
has not been installed yet or is out of order ( table 14, page 32).
"Service" button ( fig. 50, [4])
The "Service" button is used to display the current space heating water
temperature, the current system pressure etc.
