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.
