USER'S GUIDE

HOW TO USE THIS MANUAL

This manual is for the exclusive use of ACV-approved installers.

The rst section of the manual contains a description of the ACVMax controller and of the keys, screens

and menus used to make the adjustments.

The next section presents various heating system diagrams and the list of the accessories required

for each specic system. The electrical connection diagrams are also included as well as the specic

settings of the ACVMax to be made using the installer access code provided in this manual.

Finally, the last section contains the explanation of the status and information messages as well as the

blockage and error codes displayed on the ACVMax screen, which will allow the installer to troubleshoot

the possible faults.

For any other heating system conguration than those in this manual, please contact your ACV repres

entative.

BOILER EASY SETUP

The main parameters of the Prestige boilers can be set up using the EZ (easy) setup function of the

controller. The EZ setup function allows the user/installer to quickly setup the appliance for immediate

operation according to the system conguration. Refer to the appliance Installation, Operation and

Maintenance Instructions.

APPLIANCE DESCRIPTION AND OPERATION

ACVMAX OPERATING INFORMATION

The ACVMax system control is designed to be exible yet easy to use. It monitors and controls the

boiler to operate as eciently as possible. ACVMax monitors the boiler supply, return and ue gas

temperatures and operates the igniter, gas valve and blower. It uses this information to modulate the

boiler’s ring rate to maintain the required setpoint. ACVMax oers many advanced control options,

which may be adjusted for various applications to achieve optimum boiler eciency and operation.

• Two central / space heating (CH) call inputs with separate outdoor curves.

• A Domestic Hot Water (DHW) call input with optional priority.

• System temperature sensing and control with an optional system temperature sensor.

• A cascade function. It allows up to four Prestige Solo boilers (2 pumps) to operate together in a single

heating system.

• A Modbus interface for integrating with building management systems.

These advanced features are adjustable in the Installer Menu after entering an access code. Refer to

"Installer Code" on page 5 for more details

CONTROL PANEL DESCRIPTION

1. ACVMax LCD Display - It is the setup interface of the boiler and indicates the parameter values,

the error codes and the set-up status of the parameters. It displays a series of screens, each showing

information and/or icons. The main icons are detailed hereafter.

2. Installer button - Allows the installer to access the menus of the ACVMax controller to set up the

system.

3. Arrow keys and OK key - To browse through the screens of the ACVMax controller, set up the boiler,

increase and decrease the displayed values and validate the selections and access the Easy set-up screens.

The OK key is also used to RESET the boiler after a blocking (following the instructions on the screen).

HOME PAGE DESCRIPTION

INSTALLER CODE

Through the use of the specic code «54», the installer can access various setup screens, in order to

dene a large set of parameters and adapt the operation of the ACVMax to the system conguration.

To navigate on the screen, use the UP, DOWN, LEFT and RIGHT keys, OK then the OK key to validate

a selection. To increase/decrease values, use the UP and DOWN keys. or LEFT and RIGHT,

according to the situation

General remarks

• Entering the installer access code allows the installer to make adjustments for 30

minutes. After 30 minutes, the access code will need to be entered again to make any

adjustments.

• If the end user misuses the installer code to access installer-specific parameters and

makes changes that cause a system failure, any warranty claim will be void.
