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 efficiently 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 offers many advanced control options, which can be adjusted
for various applications to achieve optimum appliance efficiency 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
for more details.

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.
