[TRNSYS-users] Dynamic efficiency

[Seyyed Tajdaran]

That's brilliant

The thing I am just struggling to follow is, if for instance for a boiler
the input value for the boiler efficiency is set and the Macro button is
toggled, are we expecting the efficiency to stay fixed during the time? and
how the macro is impleneted here. The problem is I can't find the
documentation of Boiler's in 2017 version.
