Minimum blower speed adjustment for heating
It is possible to set the minimum speed of the blower for the heating

Setting the climatic curve
The appliance is equipped with an outdoor temperature probe (located
onboard the appliance) that acts by automatically changing the outlet tem-
perature according to the measured outdoor temperature. The extent of the
correction depends on the set heating control value Kd (Figure 5.3
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.

1. The climatic curve and the use of the 0-10 V input are
alternative functions. If both functions are configured
as active, the climatic curve is used. These functions
are only used in the case of control via external re-
quest (P78 = 2).
2. With the climatic curve active, the outlet water setpoint
temperature is set to a value between that of param-
eters P69 and P70 based on the outdoor temperature
measured by the probe inside the appliance and on
the Kd value set in parameter P66 (Figure 5.3
3. With 0-10 V input active in temperature control mode,
the outlet water setpoint is set to a value between that
of parameters P69 and P70 based on the line passing
through the points (3 V, P69) and (10 V, P70). A volt-
age lower than 3 V corresponds to no service request.
With 0-10 V input active in power control mode, the
thermal output is set to a value between the minimum
and maximum power according to the line passing
through the points (3 V, minimum power) and (10
V, maximum power). A voltage lower than 3 V corre-
sponds to no service request. Control via 0-10 V input
is not available for AY 100.
