4.2.1.8 Cylinder charging pump
Connecting the cylinder charging pump
The cylinder charging pump outlet is always actuated if an external cylinder is being charged using
the unit's internal control system.
4.2.1.9 Extraction hood/flue non-return flap
Connecting the flue non-return flap (black), fume extraction hood (grey)
The extraction hood is switched on when the burner is not running or 90 seconds after the unit has
switched off. Otherwise, the extraction hood is locked by the module.
The flue non-return flap is actuated in the event of a heat requirement by the temperature control, in
the event of a hot water demand, in cylinder charging mode and in the 90 seconds after the lapse of
the heat requirement

Closing contact = flue non-return flap = black

Opening contact = fume extraction hood = grey
4.2.1.10 Flue non-return valve return signal
The flue non-return flap end switch reports the current position of the flue non-return flap via a two-
pole wire, which is connected to a separate terminal.
The flue non-return flap end switch is closed if the flue non-return flap has reached its end position
after start-up and is opened when the flue non-return valve closes. The burner is started when the
flue non-return flap is opened and the end switch is closed.
