01=Minimum power scanning test

04=heating power scanning test

03=30 Seconds

06=60 Seconds

18=180 Seconds

The % power required this is done

in the following example i.e. if you

require 18KW then the calculation is

as follows 100 / 28 x 18 = 64 (for a

28KW boiler) or 100 / 40 x 18 = 45

(for a 40KW boiler)

04=running all the time
