CHAPTER 9 - ACVMAX OPERATION
The ACVMax Boiler Management System is designed to
be exible yet easy to use. ACVMax monitors and con-
trols the PRESTIGE Solo to provide heat as eciently
as possible. ACVMax 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 ACVMax 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 ACVMax features are easy to use through a graphical
display where information is presented either graphi-
cally or in plain English, so code charts are not required.
Fig. 25 shows an ACVMax display example of the PRES
TIGE Solo red for a domestic hot water demand.
