8.4.2 Analog control (0 -10 Volt dc)

The heat output modulates between the minimum and the maximum value on the
basis of the voltage supplied by an external analog (0 -10V, volt free) input (terminal
connections 1 (gnd) and 2 (+)).
- Temperature based (20 to 90°C) set the x value of the boiler control operation
parameter (A) to 4.
To set the ratio between voltage and the desired flow temperature, see Par. 6.6.15
and the graph below.
- Output based - fixed parameters (18 to 100%), see graph below.
0 Volt = boiler off
0.5 - 1.8 Volt = heat input 18%
1.8 - 10 Volt = boiler modulates between 18 and 100% on demand
Set the x value of the boiler control operation parameter (A) to 5.
NOTE: When using an external analog (0 -10V), the factory default 03should be
changed to 00.
