Weather Compensation Curves

EY.65.H4.02

22

7.1  Adjusting the Flow Temperature Curve

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.

1.

Press 

 to select the desired heat circuit.

2.

Press 

 to display the flow temperature 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.

Moving curve
points

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.

!

Note:
If two curve points are placed in the same position, one point is automatically re-
moved.

Setting maximum
and minimum val-
ues

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.

Adding and re-
moving curve
points

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).

11. Use 

 to add a breakpoint or 

 to remove one.
