11.2 External control signal 0…10 V to regulate start-up and power modulation of each boiler
The external electric signal 0…10 V must be connected to the terminals shown in the electric
cabinet of the boiler. The signal 0…10 V will transmit to the boiler a set-up temperature value.
Voltage
0,15V U1=0V U2=10V

temperature
setpoint
F2=85ºC
F2=65ºC
These are the predefined 0...10 V values in
configuration
:
These are the setpoints that we get from 0...10 V demand:
Voltage (V) Setpoint (ºC)
1 22
2 29
3 36
4 43
5 50
6 57
7 64
8 71
9 78
10 85
If it is necessary to get different values of temperature, change the following values to get a new linear characteristic:
m = (F2-F1) / (U2-U1)
F2 = Final Temperature (ºC)
F1
= Initial Temperature (ºC)
U2 = Final Voltage (V)
U1 = Initial Voltage (V)
First of all, calculate the new slope of the linear characteristic with the new 2 fixed points (initial and final points). Once
you get the new relation ºC/V, use it to the new characteristic in order to get the new temperature setpoints.
F2 = m·(U2-U1) + F1
