ECO MODE - Heating curve
In ECO Mode, the unit runs according to heating curve. The heating curve is the relationship between the
heating system supply temperature and the outside air temperature. In the case of a heating curve, it is
done automatically thanks to the weather-based control, which adjusts the supply temperature based on the
outside temperature.
Press simultaneously
settaggio/impostazione dei parametri b17, b18 and b19 as in the list above.
The heating curve parameters setting is only for technician operation.
a. In main menu, press
to set parameters. Press
b. In parameter setting menu, if there is no operation for 30 seconds, will automatically exit
parameter setting and back to main menu. Or press
N° Description
b17 Set room temp
b18 Initial BTW temp
b19 Max. BTW temp
Target Buffer Tank Water temp = Initial BTW temp + (Max BTW temp - Initial BTW temp) / 35 x (Set room
temp - Outside temp)
For example, Set room temp = 25° C, Max BTW temp = 43° C, Initial BTW temp = 20° C
a. When outside temp= 20° C, Target buffer tank temp = 20+(43-20)/35x(25-20)=23° C
b. When outside temp= 0° C, Target buffer tank temp = 20+(43-20)/35x(25-0)=36° Cc.
c. When outside temp= -15° C, Target buffer tank temp = 20+(43-20)/35x(25+15)=46° C
2. When Air temperature sensor failure, in OFF status, in DHW mode, and in cooling mode, the unit doesn't
run according to heating curve.
3. When the unit is working in ECO mode, it only works according to the heating curve, can't set temperature
by controller or App.
