6.3.1 Commissioning - quick set-up
This section allows the user to carry out the minimum commissioning necessary to operate
the system for two typical applications.
It accepts the defaults set in the factory, so will only work if the original default settings have
not been altered. See default settings in Section 10, Technical information, to confirm.
Settings can then be tailored to suit the individual requirements of the customer / application
if required.
WARNING: It is essential that you comply with National / local regulations and
Guidance notes, and the boiler manufacturer’s recommendations. It is imperative
that the settings you have accepted will allow the boiler to operate in a safe manner.
