Minimum blower speed adjustment for DHW

It is possible to set the minimum speed of the blower for the DHW service, which
corresponds to the minimum power of the burner during a DHW request (see Figure
5.8

p. 43). The value is preset according to the set power (parameter P00) and the

type of gas (parameter P02).

P11 (1) (2)

Maximum blower speed adjustment for DHW

It is possible to set the maximum speed of the blower for the DHW service, which
corresponds to the maximum power of the burner during a DHW request (see Figure
5.8

p. 43). The value is preset according to the set power (parameter P00) and the

type of gas (parameter P02).

Value in hertz (1 Hz = 30 RPM)

P12 (1)

Minimum blower speed adjustment for heating

It is possible to set the minimum speed of the blower for the heating service, which
corresponds to the minimum power of the burner during a heating request (see
Figure 5.8

p. 43). The value is preset according to the set power (parameter P00)

and the type of gas (parameter P02).

Maximum blower speed adjustment for heating

It is possible to set the maximum speed of the blower for the heating service, which
corresponds to the maximum power of the burner during a heating request (see
Figure 5.8

p. 43). The value is preset according to the set power (parameter P00)

and the type of gas (parameter P02).

Starting step adjustment

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

Setting the climate curve (only with outdoor probe OSND009 connected)

The OSND009 outdoor temperature probe may be connected and acts by auto-
matically changing the outlet temperature according to the measured outdoor
temperature. The extent of the correction depends on the set heating control value
Kd (Figure 5.6

p. 42). The choice of the curve is determined by the maximum outlet

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

sponds to the 'Kd' curves of the graph

DHW buffer tank setpoint differential

It is possible to set the differential value with respect to the DHW setpoint at which
the DHW buffer tank charge is activated. For example, with the DHW setpoint at 50
°C and the parameter value at 5 °C, DHW buffer tank recharging starts at 45 °C (50-5)
and stops when the storage reaches the DHW setpoint. The parameter is only active if
the buffer tank probe OSND011 is connected.

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.

Min heating setpoint

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