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.

On Lockout and Blocking
On Lockout
•
On Lockout, Blocking and Warning: the error relay is activated at a non-volatile lockout (e.g. CH Flow NTC defect), at a blocking error (self-resetting errors) (e.g. Gas-pressure switch not closed ), or at a warning (e.g. low water pressure warning).
•
On Lock-out and blocking: the error relay is activated at a non-volatile lock-out or a
blocking error.
•
On Lockout: the error relay is activated at a non-volatile lock-out only.
The selection depends on the alarm feedback requirement from the customer.

Stage Delay sets the time delay before enabling or disabling a boiler in the Cascade System.
The Stage Delay begins once the Master boiler determines that a boiler must be enabled to
reach the setpoint or when the Master boiler determines a boiler should be disabled because
of a decreasing load.

Adjusting the Stage Delay will have the following effects:
0 sec.
255 sec.
• Increasing Stage delay
DE
- Reaching the setpoint could take longer due to a longer delay between enabling boilers.
- Overshooting the setpoint could occur due to boilers staying on longer before being disabled.
• Decrease Stage delay
- Overshooting the setpoint could occur due to boilers being enabled quicker.
- Boilers will be disabled quicker, possibly increasing boiler cycling and decreasing runtimes.

Setting the Minimum Firing Rate below the recommended minimum will result in boilers being
enabled too quickly which may cause sharp increases in temperature from the Cascade System.
Setting the Minimum Firing Rate above the recommended minimum will delay the enabling of
boilers which may lower the system efficiency.
Press the LEFT or RIGHT buttons to adjust the Minimum Firing Rate then press the OK button
to store the setting.
Default : 25%
Only make changes after being instructed to do so by ACV as changing of this

The CH or DHW Boilers setting specifies how many boilers in a Split Cascade System will respond to a domestic hot water call. The CH or DHW Boilers always include the Master boiler. The
remaining boilers will only respond to central heating calls. This allows the Cascade System to
satisfy both central heating and domestic hot water calls at the same time. At the completion
of a domestic hot water call, the CH or DHW Boilers will again be available to respond to central
heating calls.
Press the LEFT or RIGHT buttons to adjust the CH or DHW Boilers setting then press the OK
button to store the setting
DE
The maximum number of boilers in a cascade is 4. Therefore, do not select a higher
number than 3 in this menu as one should never adjust to the same number as he
has appliances in the cascade. This would override the Split of the system. Failure
to comply may result in faults in the cascade operation.

Through the Auto Rotation function, the number of burning hours is equalized over all appliances.
When the function is Enabled, the appliances will all run an equal amount of time. This helps
balancing wear over the appliances.
When the function is Disabled, there is no levelling of burning hours and the first appliances in
the sequence will run more than the last one in the sequence.

The Cascade System must be configured after wiring is completed and any required
adjustments are made in Cascade Settings. Refer to "Cascade system connection (4-boiler
Cascade)" on page 50 before using this function.
The Cascade Autodetection function automatically finds and configures all boilers in the Cascade System.
This eliminates the need to manually configure each boiler of the Cascade System. Select Cascade Autodetection on the Master boiler then follow the on-screen instructions to perform Cascade Autodetection.
NL
Once Cascade Autodetection is finished, a message will be displayed indicating how many boilers have
been found. If the number of boilers found is correct, press OK to finish Cascade Autodetection.
If the number of boilers found is not correct, check the cascade communication cables between the boilers
and repeat Cascade Autodetection process.

CONFIGURATION OF REGULAR SYSTEMS - PRESTIGE SOLO/EXCELLENCE (3-WAY VALVE)
FR
NL
ES
GENERAL
PUMPS
This section contains information on the electrical connections, hydraulic connections and ACVMax
controller set-up for Prestige 24-32 Solo/Excellence, that are required to operate the system
configuration you have selected.
For simple configurations, the EZ setup function of the ACVMax can be used (refer to the Installation,
Operation and Maintenance manual provided with the appliance).
For more complex systems, with additional pumps, several configurations have already been preset
in the ACVMax controller to help you. Please refer to the following pages to see the predetermined
configurations.
For any system that is not mentioned in this manual, please contact your ACV representative.
The pump configurator system is based on the demands of the hydraulic system that you design. In the
table below, you will find the 4 configurations that have been preset in the ACVMax controller for the
Prestige 24-32 Solo/Excellence (identified as "Solo/Excel. (3-way valve)" in the Prestige Model selection
menu), based on different hydraulic schemes that can be used.
The table shows which relays are activated under which condition.
The names in the table refer to the demand done by CH1 by CH2 or DHW respectively, the demand to
open/close the Motor of a mixing valve or reflect the activation of the alarm (error) or Flame output relay.
In the following pages, you will find these diagrams with a configuration number that corresponds to
the setting in the display.

Description
Standby
Indicates that the Prestige is ready to respond when a demand is received.
CH Demand
A central heating call has been received.
DHW Demand
A domestic hot water call has been received.
CH / DHW Demand
Central heating and domestic hot water calls are being received simultaneously. Both calls are being satisfied simultaneously because domestic hot
water priority has been disabled.
DHW Priority
Central heating and domestic hot water calls are being received simultaneously. Domestic hot water call is being satisfied first because it has priority
over central heating calls.
Priority Timeout
Central heating and domestic hot water calls are being received simultaneously. The domestic hot water priority time limit has been exceeded.
Priority will now switch back and forth between central heating and domestic hot water calls until one call is satisfied.
External Demand
An external modulation call has been received.
Slave Operation
The Prestige is a slave in a cascade system.
Manual Operation
The burner or circulators have manually been enabled in the Installer Menu.
CH Burner Delay
The burner will not fire until the call blocking time has elapsed.
DHW Burner Delay
The burner will not fire until the call blocking time has elapsed.
CH Setpoint Reached
The burner is not fired because the supply/system water temperature exceeds the setpoint. The central heating circulator continues to operate and
the burner will fire again once the supply/system water temperature drops below the setpoint.
DHW Setpoint Reached
The burner is not fired because the supply/system water temperature exceeds the setpoint. The domestic circulator continues to operate and the
burner will fire again once the supply/system water temperature drops below the setpoint.
CH Post Pump
The central heating circulator is running to remove heat from the Prestige at the completion of a call.
DHW Post Pump
The domestic hot water circulator is running to remove heat from the Prestige at the completion of a call.
Freeze Protection
Freeze protection will end once the supply/system water temperature is raised to 16ºC.
Boiler Protection
The burner firing rate is being reduced because of an excessive difference between the boiler supply and return temperatures. The firing rate will
begin increasing once the temperature difference is less than 25ºC.
Lockout Description
The lockout which currently has the Prestige shut down is displayed.
