3.16 CH OUTPUT ADJUSTMENT.
If it is necessary to change the CH output, you will need to adjust
the "P08" maximum CH output and "P09" minimum CH output
parameters.
To check the regulated heat output value, compare the no. of fan
revs with that in the table (par. 4.1).
3.17 OUTPUT ADJUSTMENT DURING DHW (ONLY IN
COMBINATION WITH AN OPTIONAL EXTERNAL
STORAGE TANK).
If it is necessary to change the DHW output, you will need to
adjust the "P20" maximum DHW output and "P21" minimum
DHW output parameters.
To check the regulated heat output value, compare the no. of fan
revs with that in the table (par. 4.1).

3.18 "CHIMNEY SWEEP" FUNCTION.

This function allows the technician to check the combustion
parameters. Boiler operation in chimney sweep function can be
adjusted to an output between 0% and 100%.
To enable the function press and hold down "A"
If there is a common flow probe, it is possible to activate the chim-
ney sweep function by pressing buttons "A" and "B" simultaneously.
In this case, the plant pump is activated as well as the boiler (in
the "simple cascade" both boilers are activated).
The output is adjusted from the + and - DHW adjustment buttons
at a range between 0 and 100%, while using the + and - buttons
for CH adjustment, the percentage changes by 1% each time they
are pressed.
In this state all adjustments are excluded and only the temperature
safety thermostat and the limit thermostat remain active. When
the checks are finished disable the function by pressing and hold-
ing down button "A" (or "A" + "B" in the other case).
If you enable the function, you will need to wait approximately
30'' to reach the set output (3' on the Slave boiler).
3.19 3-WAY PUMP ANTI-BLOCK FUNCTION
(OPTIONAL).
The boiler has a function that starts the pump and 3-way valve
at least once every 24 hours for the duration of 20 seconds in
order to reduce the risk of the pump becoming blocked due to
prolonged inactivity.

3.20 RADIATORS ANTI-FREEZE FUNCTION.

The boiler has a function that makes the pump start when the
system flow water reaches 8 °C. If the system flow water is at a
temperature below 5 °C, the boiler starts to operate until it reaches
approximately 16 °C.

3.21 ANTI-HUMIDITY ELECTRODE FUNCTION.

With cascade installations combined with their relative flue mani-
fold kits with flue adjusting devices, humidity may develop on the
electrodes, causing them to fail. Avoid the formation of humidity
by enabling this function (by setting a value other than 0), which
turns the fan on at the speed set in parameter "P11" (5 minutes on
and 5 minutes off). The function is active when the burner is off
and the flow NTC probe temperature reading is greater than 35°C.
The function is disabled when the temperature drops below 30 °C.
3.22 INLET 0 ÷ 10 V.
The microprocessor has an analogue 0 ÷ 10 V inlet ("Y" and "Z"
terminals fig. 5) that enables the boiler to be controlled from the
outside.
By setting the "P37" parameter, it is possible to set-up the inlet
by choosing the functioning mode between temperature set and
power set.
The inlet activates a 2 V (minimum) request and increases it pro-
portionally up to 9.5 V (maximum). The request is deactivated
below 1 V.

Notes:
- If "P37" is set at "0", it is not active when the boiler is in "stand-
by" or "summer" mode.
The calculated set is limited by the "P02" ÷ 20 °C range. The
maximum and minimum temperature within the set is limited
by "P01" and "P32".
- If "P37" is set on "1" it is always active.
It is not limited by the "P08" and "P09" parameters and does not
have priority over the DHW request.
- Input voltage = -2.5 ÷ 12.5 V
- Input = 200 μA
- Impedance = > 50 KΩ
