CHAPTER 9 - CTRLMAX OPERATION
The ControlMax (CTRLMax) Boiler Management System
is designed to be exible yet easy to use. CTRLMax
monitors and controls the PRESTIGE Excellence to pro-
vide heat as eciently as possible. CTRLMax includes
many advanced features:
• Two central/space heating (CH) call inputs with
separate outdoor reset curves.
• Domestic Hot Water (DHW) call input with optional
priority.
• EZ Setup feature allows the installer to quickly cus-
tomize CTRLMax for each installation.
• Mixing valve control to simultaneously heat dual
temperature heating systems.
• Cascade function allows up to six PRESTIGE Solo boil-
ers to operate together in a single heating system.
• Modbus interface for integrating with building
management systems.
All CTRLMax features are easy to use through a graph-
ical display where information is presented either
graphically or in plain English, so code charts are not
required. Fig. 21 below shows an CTRLMax display ex-
ample of the PRESTIGE Excellence red for a domestic
