Maximum Heating Power adjustment
2
2
The maximum heating power can be adjusted between the
maximum power allowed by the boiler (22.5kW - ACO 27 and
28kW - ACO 32) and the minimum recommended power (10kW
- ACO 27 and 13kW - ACO 32) indicated in the graph below
(Parameter
2
= 20%). The value is factory set to 70% of the
maximum power.
The value set (expressed as a percentage) can be displayed
and modified as illustrated in Section 3.6.1 (parameter 2).
The display shows the value between 100% ("00" on the display)
and 1% ("01").
Use the graph below as a guide to set the boiler heating power to
suit the system load.
