C. Technical Menu - Cascade Master Menu Structure
The technical menu levels and parameter selection options for
boilers configured as Master and Followers are different than those
configured as standalone boilers. The differences are as follows:
Master Boiler
– Retains the technical menu levels available in a
standalone boiler while adding menu level 25 for parameters speci-
fic to Cascade Management.
NOTE:
Some parameters normally ac-
cessed via menu levels 2 and 8 for a single boiler are now accessed
via the Cascade Management menu – see below:
• Automatic Temperature Control moves from 2.2.4 to 25.1.0
• Outdoor Temperature Reading Correction: from 2.4.9 to
25.1.1
• CH Boost Interval: from 2.4.4 to 25.1.2

Follower Boiler
– Retains technical menu level 0 for setting the boiler
address. Loses menu levels 4, 5, and 6 normally used for managing CH
settings (Followers do not manage CH), and moves menu levels 2 and
8 to new menu level 34 (for Follower 1) [35-40 for Follower 2-7].
NOTE:
The Master boiler also has access to the Follower menu of each
Follower in the cascade system.
