First start-up

P02

Gas type selection

WARNING: before changing the parameter value, read the instructions in Para-
graph 5.6

p. 33.

0 - 1

0 = G20, G25, G25.3
1 = LPG, G30, G31

P03

Heating temperature setting

0 - 1

0 = standard (30-80 °C)
1 = reduced (25-45 °C)

P04

Heating run-up

It is possible to set the time, during the start-up phase, that the boiler takes to
reach the maximum set power (for the space heating service).

0 - 5

0 = disabled
1 = 50 s
2 = 100 s
3 = 200 s
4 = 400 s
5 = 600 s

P05

Primary ignition time of a single unit

Time for which a single unit becomes primary at startup, after which the automat-
ic changeover with the other unit takes place.

0 - 255

Value in hours

P06

Switching off a single unit

1 - 3

1 = only master on
2 = only slave on
3 = both on

P07

Heating timing

You can set the minimum time in which the burner is kept off once the heating
temperature has reached the setpoint.

0 - 90

Value in multiples of 5 s (default 36 x 5
= 180 s)

P08

Post-circulation heating timing

It is possible to set the operating time of the pump, in heating mode, after the
main burner has been switched off due to the intervention of the room thermo-
stat.

0 - 90

Value in multiples of 5 s (default 36 x 5
= 180 s)

P12 (1)

Heating blower minimum speed adjustment

It is possible to set the minimum speed of the fan for the heating service, which
corresponds to the minimum power of the burner during a heating request (see
Figure 5.7

p. 31). The value is preset according to the set power (parameter P00)

and the type of gas (parameter P02).

45 - P13

Value in hertz (1 Hz = 30 RPM)

P13 (1)

Heating blower maximum speed adjustment

It is possible to set the maximum speed of the fan for the heating service, which
corresponds to the maximum power of the burner during a heating request (see
Figure 5.7

p. 31). The value is preset according to the set power (parameter P00)

and the type of gas (parameter P02).

P12 - 203

Value in hertz (1 Hz = 30 RPM)

P14 (1)

Starting step adjustment

It is possible to set the fan speed during the start-up phases. The value is preset
according to the set power (parameter P00) and the type of gas (parameter P02).

P10 - 203

Value in hertz (1 Hz = 30 RPM)

P16

Setting the climate curve (only with outdoor probe connected)

An outdoor temperature probe may be connected and acts by automatically
changing the delivery temperature according to the measured outdoor temper-
ature. The extent of the correction depends on the set Kd heating control value
(see Figure 5.6

p. 31). The choice of the curve is determined by the maximum

delivery temperature Tm and the minimum outdoor temperature Te, taking into
account the degree of insulation of the house. The values of the delivery tempera-
tures Tm refer to standard systems 30-80 °C or floor systems 25-45 °C. The type of
system can be set using parameter P03.

0 - 30

The numbering of the value corre-
sponds to the 'Kd' curves of the graph
(see Figure 5.6

p. 31)

P18

0-10 V industrial bus drive enable

The 0-10 V industrial bus input can be enabled or disabled to set burner power or
delivery temperature via the external bus.

0 - 2

0 = disabled
1 = temperature control mode
2 = power control mode

P19

Min heating setpoint

It is possible to set the minimum user-adjustable heating temperature.
