CONFIGURATION AND SYSTEM SET-UP
CONFIGURATION AND SYSTEM SET-UP
CASCADE
Several Prestige Solo boilers can be setup in a cascade configuration that is controlled by the ACV-
MAX Boiler Control System.
The boilers can operate together without the need for an external cascade controller. One Prestige
will be selected as the Master and will be wired to accept all the low voltage control signals and all
the system pumps. The other Prestige boilers will be designated as Slaves and will only have a com-
munication cable connecting them to the other boilers in the Cascade System.
• The Cascade function allows up to four identical Prestige boilers to operate together in a single
heating system.
• Parallel Modulation fires as many boilers as possible to maximize system efficiency.
• The Auto rotation function rotates the lead boiler every time a call for heat is received when a
Thermostat option is chosen in CH Demand or every 24 hours when a Constant option is chosen
in CH Demand.
For more information and system setup, refer to the Installer’s Handbook manual (also available on
www.acv.com).
SYSTEM CONFIGURATIONS
The Prestige Solo boilers can be setup in different types of systems, either high or low temperature,
or both, with or without Domestic Hot Water tank. They can also be configured in a Cascade system
(using a Prestige Box or not - see on the right).
It is up to the installer to determine the best solution for the results the user is expecting.
One basic configuration is shown in this manual (see following pages), with the required accessories,
required electrical connections and ACVMAX setup using the EZ setup function.
Additional configurations requiring more advanced setup are shown in the Installer’s Handbook
(available on www.acv.com). The setup of those systems must be made exclusively by the installer
using the installer code.
For any other configuration that is not mentioned in either manuals, please contact your ACV rep-
resentative.
PRESTIGE BOX
The Prestige Box is a heating system for commercial buildings. This complete heating module hous-
es several boilers (up to 4) and consists of a specifically-designed insulated cabinet that can be
located outdoors. It is also protected against frost in cold weather conditions through the anti-frost
features of the boiler(s), and the insulation of the tubes.
The Prestige Box is comprised of a condensate neutralisation system, an expansion vessel, an elec-
tric box and safety devices among other things. Optional items can also be added in the cabinet.
The front door(s) of the cabinet can be opened for easy access to the items located inside and for
maintenance purposes.
The cabinet contains several Prestige boilers (from 2 to 4), that are hydraulically and electrically con-
nected to one another in a cascade configuration. Each boiler has however its own chimney connec-
tion. The system control is performed by the Master boiler in the cascade through the ACVMax pro-
cessor. For more information on the cascade function of the ACVMax, refer to the Installer’s Handbook,
available on www.acv.com. (ref 660Y2900).
