04.09
Burner PID integral factor.
Weight of the integral factor taken as
a reference by the PID system. The integral length is necessary
to ensure accuracy at full operation. Nevertheless, if this value is
too high, it can cause excessive overshoots before reaching the
setpoint. It can also cause fluctuations around the setpoint.

04.10
Burner PID derivative factor.
Value of the derivative factor taken as a reference by the PID
system. The derivative length, duly sized, favours stability (i.e.
a protection against excessive overshoots), but it does not
contribute to ensure accuracy at full operation. The derivative
component tends to mitigate the harsh direction changes of
temperature trend, which are due to a possible excessive action
of the integral and proportional components. It also increases
control responsiveness to sudden load variations.
0-20 - 5 SERVICE SERVICE ALWAYS
04.11
Variation maximum speed
It represents the maximum speed to increase and decrease
speed modulation.
0-20 %/second 10 SERVICE SERVICE ALWAYS
04.12
Level probe filter.
Number of transducer readings used to calculate the average
value. Readings take place every 100 milliseconds.
0-100 - 10 SERVICE SERVICE ALWAYS
04.13
Pump manual operation. By activating this function, the selected
pump is activated until boiler maximum level. The modulating
pump is forced to the maximum.

07.03
TDS alarm threshold.
TDS level above which burner is stopped and the relevant alarm
is triggered.
0 – 6000 µS 6000 USER USER
If the TDS
sensor is
enabled
07.04
TDS alarm hysteresis.
When the TDS value drops under the alarm threshold minus
this hysteresis, the alarm will be reset and the burner will be
restarted.
0 – 1000 µS 100 USER USER
If the TDS
sensor is
enabled
07.05
TDS valve opening threshold.
TDS level above which the TDS valve is opened intermittently.
The valve is opened and closed intermittently based on
parameters 07.07 and 07.08. For TDS2: When the intermittent
opening is active, the TDS value is read during openings,
parameters 06.02 and 06.03 are not active.
2000 – 6000 µS 4000 USER USER
If the TDS
sensor is
enabled
07.06
TDS valve opening hysteresis.
When the TDS value drops under the opening threshold minus
this hysteresis, the valve stays closed.
1 – 1000 µS 100 USER USER
If the TDS
sensor is
enabled
07.07
TDS drain valve opening time.
TDS valve opening time for drainage (washing) and consequent
dilution (for TDS lowering).
1 – 99 s 15 USER USER
If the TDS
sensor is
enabled
07.08
TDS drain valve pause time.
Duration of TDS pause time during drainage (washing).
1 – 999 s 30 USER USER
If the TDS
sensor is
enabled
07.09
TDS enabling.
Off: Valve always closed, no alarm is triggered when threshold is
exceeded and burner is not stopped. The read TDS value flashes
to indicate that the TDS control is disabled. No alarm is triggered
even in case of faulty TDS probe. Four dashes “µS - - - -“ will flash
instead if the read value
On: The valve opens according to the programmed automatisms,
when the threshold is exceeded, the alarm will be signalled and
the burner turned off.
