External power demand
The type of power demand can be set using the parameter “Source for external power demand. (0 –
off, 1 – 0-10 V, 2 – modbus)“. The percentages are transferred directly if the power demand is made
via modbus. If 0-10 V is selected as the source, the boiler release/boiler output can be controlled via an
adjustable input at the analogue module using a voltage signal.
Method of operation for wood chip boiler and pellet boiler
If the signal at the input is above 35%, the boiler starts in continuous load mode; if the signal drops below 30%,
the boiler shuts down.
By default 0V = 0% and 10V = 100%. This can be changed using the “Invert ext. power demand via
analogue input” parameter.
To initiate start-up via the power demand, “Automatic” mode must be selected and the contact must be closed
if a release contact is used (“Boiler release input available” parameter = YES).
Necessary parameters for setting the power demand can be found in the “Boiler – General settings” menu.
