Curvepoints P2 to P8 are automatically computed as a straight line
between P1 and P9
.
Example 1 = gas modulating
P0
,
P1
and
P9
are set as described
Curvepoint Value 1 fuel Value 2 air
P0 30.0 22.0
P1 32.0 24.0
P9 80.0 90.0
P2 through P8 have automatically
been calculated:
Curvepoint Value 1 fuel Value 2 air
P2 38.0 32.3
P3 44.0 40.5
P4 50.0 48.8
P5 56.0 57
P6 62.0 65.3
P7 68.0 73.5
P8 74.0 81.8
It is important to set P0 and P9 as accurately as possible.
These settings are used to calculate the remaining
curvepoints once the burner has started.
Curvepoint P1 is automatically
set to the same value as P0 on
the first start. This value can,
however, be adjusted once the
burner has started.
To simplify the setting work involved for each curvepoint, do as follows:
1.
Check that good combustion is achieved at P1 ; adjust if necessary.
2. Move along to P2 and check/adjust for good combustion.
3. Calculate the curvepoints between P2 and P9 by pressing > on
+
.
4. Now move along to P3 and repeat the process described.
5. Repeat the process until curvepoint P9 has been reached.
This method makes the setting work easier and faster to complete. A more “correct”
setting is obtained straight away. The process may need to be redone if the wrong
input power was set for
P9
initially. For this reason, be extremely careful when entering
the first setting of P9 .
