USER’S GUIDE
HOW TO USE THIS MANUAL
The Installer's Handbook is for the exclusive use of ACV-approved installers. The manual
contains all relevant information to set up a system based on an Evo appliance controlled
with ACVMax Touch.
It contains:
• A general description of the ACVMax Touch interface controls, functions and icons
• A detailed description of all the screens, menus and parameters, with the exception of
the Cascade menus. As ACVMax cannot control an Evo cascade, the cascade menus
and functions are not described in this manual.
Cascades of Evo appliances must be controlled by an external controller (e.g. Bus-
connected).
• A series of typical hydraulic diagrams for dierent system configurations, as well as the
parameter settings for each configuration, when applicable.
• A list of the error codes displayed on the ACVMax Touch screen, the problem they are
related to and proposed solutions.
For simple configurations, the EZ setup function of the ACVMax Touch can be
used. Refer to the Installation, Operation and Maintenance manual provided
with the appliance, or get it from the Download center at www.acv.com.
For more complex systems, with additional pumps, several configurations have already
been preset in the ACVMax Touch controller to help you. Please refer to the table of con-
tents to see the predetermined configurations for the chosen appliance type.
For any other heating system configuration than those in this manual, please contact your
ACV customer support.
Finally, this manual has some interactive features : interactive table of contents, interactive
buttons, cross-references within the document, etc. Clicking on the displayed at the
top of the pages will automatically bring you back to the last viewed page.

CONTROL PANEL DESCRIPTION
ACVMAX TOUCH OPERATING INFORMATION
The ACVMax Touch controller is designed to be flexible yet easy to use. It monitors and
controls the appliance to have it operate as eciently as possible. ACVMax monitors the
appliance supply, return and flue gas temperatures and operates the electrodes, gas valve
and blower. It uses this information to modulate the appliance firing rate to maintain the
required setpoint. ACVMax oers many advanced control options, which can be adjusted
for various applications to achieve optimum appliance 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 - Not applicable to Evo appliances and not described in this manual.
The Cascade feature is not applicable to Evo units, as a cascade of Evo models
must be controlled by an external controller. Refer to the relevant Evo model
Installation, Operation and Maintenance manual for more information.
• A Modbus interface that allows integration with building management systems.
These advanced features are adjustable in the Installer Menu after entering an access
code. Refer to "Installer Code" for more details.

for five minutes.
Screen brightness - it can be adjusted at the Home screen by touching and holding
simultaneously the and soft keys for 2 seconds. Touch the and soft key to
increase or decrease the contrast. Touch to end the process.
3- Installer function - The installer is provided with full access to all available features
after simultaneously touching the and soft keys for 5 seconds and entering a
specific access code (refer to “Installer Code”).
4- Arrow touch keys and OK/Reset touch key - The ACVMax Touch navigation is per-
formed through soft keys that react to the touch and emit a short beep when tapped.
Four arrow soft keys , , , are used to browse through the screens and
menus of the ACVMax controller, set up the appliance, increase and decrease the displayed
values and validate the selections. The center soft key (OK/Reset) is used for validation
and to RESET the appliance after a blocking (following the instructions on the screen).
Exert a light and short touch (tap) on the soft keys to activate their function.
Holding the touch too long will not generate any reaction from the
ACVMax Touch, unless it is a combination of soft keys meant to be touched
simultaneously for a determined duration, as instructed in this manual. The
arrow keys can also be held longer to increase or decrease values faster.
5- Sleeping mode soft key - The soft key is used to put the appliance in a sleeping mode.
When touching the soft key, the unit is in a sleeping mode but is not
isolated from power supply. Therefore, live current is still present in the
unit. For your safety, disconnect electrical power supply to the unit before
maintenance or making any electrical connections to avoid possible
electric shock hazard. Failure to do so can cause serious injury, or death.
• When putting in sleeping mode using the soft key, the appliance will
not react to any heat demand. However, the basic appliance protection
functions (such as frost protection, etc.) remain active.
• In addition, the arrow soft keys are no longer illuminated, and the
soft key lighting is dimmed.

CH Settings
Parallel Shift allows the CH setpoint to be externally adjusted when a Constant option is chosen in Demand Type. When a Con-
stant option is chosen in Demand Type, continuous CH1 and CH2 heating calls are generated. Simultaneous CH1 and CH2 calls
will result in the Appliance operating at the highest CH1 or CH2 setpoint. The CH1 or CH2 Thermostat terminals with the highest
setpoint will be used to adjust the setpoint. If the Thermostat terminals with the highest setpoint are open, the CH setpoint will
decrease by the Parallel Shift Value. If the Thermostat terminals with the highest setpoint are closed, the CH setpoint will return
to the highest CH1 or CH2 setpoint
Touch the LEFT or RIGHT soft keys to adjust the Parallel Shift Value then touch the OK key to store the setting.
Default: 0°C
CH Call Blocking sets the minimum time between burner firings for central heating calls. At the completion of a burner firing,
the CH Call Blocking time will begin. The burner will not fire again until after the CH Call Blocking time has elapsed. The CH
Call Blocking time only prevents the burner from firing, the central heating circulators will respond to a central heating call. This
blocking time has no aect on domestic hot water calls. The CH Call Blocking feature prevents short cycling of the burner and
extends the life of the burner components.

is chosen in DHW demand.
• Increase this value up to at least 70°C to enable the DHW Boost function
The DHW on differential setting greatly affects the production of domestic hot water. A low setting could result in a rapid
response to a domestic hot water call resulting in a potential scald hazard. It is strongly recommended that the installer
use a thermostatic mixing valve on the hot water outlet of the Indirect Water Heater. Failure to comply could result in
severe personal injury, death, or substantial property damage.
DHW Storage Adder is used to compute the appliance setpoint when the Sensor option is chosen in Demand Type. The appli-
ance setpoint will be DHW Setpoint + DHW Storage Adder for a domestic hot water call.

DHW To CH Call Blocking sets the minimum time between a DHW burner firing and a CH burner firing. At the completion of a DHW burner
firing, the DHW to CH Call Blocking time will begin. The burner will not fire again for a central heating call until after the DHW To CH Call
Blocking time has elapsed. This feature only prevents the burner from firing, the central heating circulators will respond to a central heating
call. This blocking time has no aect on domestic hot water calls. The DHW To CH Call Blocking feature prevents the burner from firing
when switching from a domestic hot water call to a central heating call. This allows the remaining heat in the heat exchanger to be dissipat-
ed and potentially satisfy the central heating call.
Touch the LEFT or RIGHT soft keys to adjust the DHW To CH Call Blocking time then touch the OK key to store the setting.
Default: 1 min.
The Antilegionella Function ensures that an Indirect Water Heater is heated at least once per week to prevent the growth of Le-
gionella bacteria.
Touch the UP or DOWN soft keys to select Enabled or Disabled then touch the OK key to store the setting.
• Enabled- When the Thermostat option is chosen in Demand Type, a domestic hot water call is generated for 15 minutes once
per week to heat the Indirect Water Heater.
When the Sensor option is chosen in Demand Type, a domestic hot water call is generated until the DHW storage temperature
reaches 60°C once per week. When the Sensor option is chosen in Demand Type, the weekly timer is reset whenever the
DHW storage temperature reaches 60°C to prevent unnecessary firings. This function will be active even if DHW Operation
has been set to Disabled. The appliance setpoint is at 80°C during the antilegionella cycle.
• Disabled - The Appliance will only fire in DHW mode when a domestic hot water call is received.
Default: Enabled
The antilegionella function should only be enabled when an Indirect Water Heater is installed. Enabling the
antilegionella function without an Indirect Water Heater will result in the Appliance firing once per week in DHW
mode. This could cause a Manual Reset Hard Lockout of the appliance.
The antilegionella function is most effective when the Sensor option is chosen in DHW demand. The use of an Indirect
Water Heater Sensor ensures that the domestic hot water is heated to 60°c at least once per week.
