The weather compensation curve for the flow temperature can be modified by setting:
A maximum and minimum value, 2 curve endpoints and, in addition to these, 3 break
points. Together, these parameters define the shape of the curve.
!
Note:
If you press
while a hot-water circuit is selected, the ECL 2000 displays a pop-up
informing you that this facility is not available for hot-water circuits.
!
Note:
If two curve points are placed in the same position, one point is automatically re-
moved.

1. Press
to select the desired heat circuit.
2. Press
to display the flow temperature curve.
3. Press
to display the currently defined curve
points.
4. Use
and
to move the cursor to the point you
wish to modify.
The flow temperature (y co-ordinate) of the selected
point is highlighted to indicate that it can be modified.
5. Use
and
to select either the flow tempera-
ture (y co-ordinate) or the outdoor temperature (x
co-ordinate) of the point.
6. Use
and
to adjust the selected value.
7. Ensure that the outdoor temperature of a point is
selected (x co-ordinate value highlighted), and
press
to display maximum and minimum val-
ues.
8. Use
and
to select either the maximum or
minimum setting.
9. Use
and
to adjust the selected setting.
10. Ensure that the curve's minimum value is selected,
and press
to display break points.
The checked box indicates the number of break points
that are currently active (in this example, 1 break point
is active – in addition to the two curve endpoints).
