Chimney Sweep And Manual Control Functions - andrews COMBIflo 100/300 Manual

Menu: Service/special operation
Chimney sweep function
The burner is started up. To ensure that
burner operation will be as continuous
as possible, only maximum limitation of
the boiler temperature is active to be
used as the switch off point.
To reach the minimum boiler tempera-
ture of 64 °C as quickly as possible, all
consumers are locked for that period of
time by an absolute locking signal.
When the boiler temperature exceeds
64 °C, a forced signal forces all consu-
mers to draw heat so ensure that the
boiler keeps running.
The boiler temperature maximum limi-
tation remains active when chimney
sweeper function is active.

Chimney sweep function.
Manual control
When manual control is activated, the
relays are no longer energized and
deenergized according to the control
status but are set to a predefined ma-
nual control status in accordance
with their functions (see table).
Setpoint adjustment manual control
After Manual control has been activa-
ted, one should return to the main dis-
play. There the Service/special operati-
on symbol is displayed.
The setpoint for manual control can be
changed in the info menu, which can be
reached by pushing the info-button.
When manual control is activated, the
relays are no longer energized and
deenergized according to the control
status but are set to a predefined ma-
nual control status in accordance
with their functions (see table below).
The relay outputs are set to a state
where heat is provided, independent of
their hydraulic function. The solar plant
remains switched off since there is a
possibility of storage tank recooling via
the collector. A relay energized in ma-
nual operation can be deenergized by
an electronic control thermostat (TR) or
limit thermostat (TW).
