CHAPTER 1
CHAPTER 1 - OPERATING INFORMATION
1.1. General
The ControlMax (CTRLMax) system control is designed
to be exible yet easy to use. It monitors and controls
the boiler to operate as eciently as possible. CTRLMax
monitors the appliance supply, return and ue gas tem-
peratures and operates the ignitor, gas valve and blow-
er. It uses this information to modulate the appliance
ring rate to maintain the required setpoint. CTRLMax
oers many advanced control options, which may 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 op-
tional priority.
• System temperature sensing and control with an
optional system temperature sensor.
• A cascade function (Prestige and Instinct Solo appli-
ances only). It allows, for example, up to six boilers
to operate together in a single heating system.
• A Modbus interface for integrating with building
management systems.
Accessing the functions is done through the user inter-
face, that presents itself in two dierent versions:
1.1.1 PRESTIGE and HEATMASTER Control Panel
Description
1. CTRLMax LCD Display - It is the setup interface of
the appliance 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.
2. Installer button - Allows the installer to open the ac-
cess code window of the CTRLMax controller and set
up the system once the code has been entered.
3. Arrow keys and OK key - To browse through
the screens of the CTRLMax controller, set up
the appliance, increase and decrease the dis-
played values and validate the selections.
The OK key is also used to RESET the appliance after
a blocking (following the instructions on the screen).
1.1.2 Main settings of the PRESTIGE and HEAT
MASTER CTRLMax Display
Screen backlight - it will illuminate when any key is
depressed, and remain illuminated for ve minutes.
Screen contrast - it can be adjusted at the Home screen
by pressing and holding the OK key, then pressing and
holding the LEFT key along with the OK key. Press the
UP and DOWN key to increase or decrease the contrast
while holding the OK and LEFT keys depressed. All keys
must be released and the procedure performed again
to switch between increasing and decreasing contrast.

1.1.3 INSTINCT Control Panel Description
1. CTRLMax LCD Display - It is the setup interface of
the appliance 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.
2. Installer function - By touching simultaneously the
up and down arrow keys for 3 seconds, the installer
can open the access code window of the CTRLMax
controller and set up the system once the code has
been lled in.
3. Arrow soft keys and OK/Reset key - To browse
through the screens and menus of the CTRLMax con-
troller, set up the appliance, increase and decrease the
displayed values and validate the selections. The OK/
Reset key is also used to RESET the appliance after a
blocking (following the instructions on the screen).
4. On-O soft key - To shut down the unit.
When touching the soft key, the unit shuts
down 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 servicing or
making any electrical connections to avoid
possible electric shock hazard. Failure to do
so can cause serious injury, or death.

• When shutting down using the soft key,
the appliance will not react to any heat de-
mand. However, the basic appliance pro-
tection functions (such as frost protection,
etc.) remain active.
• In addition, the arrow soft keys are no lon-
ger illuminated, and the soft key light-
ing is dimmed.
The CTRLMax navigation is performed through soft keys
that react to the touch and emit a short beep when tapped.
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 CTRLMax, 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.
Navigation through the menus and selection of items/
modication of values is performed through four arrow
soft keys , , , . The center soft key is used
for validation (and for Reset in some cases).
The installer is provided with full access to all available
features after simultaneously touching the and
soft keys for 3 seconds and entering a code.

Thermostat & Outdoor Curve – A central heating call from a dry contact
switch will enable the appliance and the setpoint will vary with the outdoor
temperature for central heating calls.
Thermostat & Setpoint - A central heating call from a dry contact switch will
enable the appliance and the setpoint will be xed for central heating calls.
Constant & Outd. Curve - The appliance will maintain setpoint and the central
heating circulators will be constantly enabled without an external call from a
dry contact switch. The central heating circulators will be disabled when the
outdoor temperature exceeds the Warm Weather Shutdown Temperature set-
ting. The setpoint will vary with the outdoor temperature for central heating
calls.
Constant & Setpoint - The appliance will maintain setpoint and the central
heating circulators will be constantly enabled without an external call from a
dry contact switch. The central heating circulators will be disabled when the
outdoor temperature exceeds the Warm Weather Shutdown Temperature set-
ting. The setpoint will be xed for central heating calls.
0 - 10V Modulation Signal - This option allows the appliance ring rate to be
controlled by an external control system with a 0-10 VDC signal. Based on the
control input voltage, the appliance will start to operate for heat demand. The
CH temperature is limited by the Absolute maximum temperature.
• 0 – 2V appliance is o.
• 2 – 10 V linear power increase from minimum to maximum output.
• 10 – 2 V linear power decrease from maximum to minimum output.

The appliance capacity can be dened by adjusting this value,
100% means Maximum CH output, 0% means minimum CH
output. It is therefore possible to adjust the CH capacity to the
installation needs.
Example: when set to 60%, the real appliance capacity is the
appliance minimum capacity plus 60% of the dierence be-
tween the maximum and minimum capacity.

CH Minimum Capacity sets the lowest limit of the CH capac-
ity. The appliance capacity can be dened by adjusting this
value and the CH Maximum capacity. It is therefore possible to
adjust the CH capacity to the installation needs.
Example: when the CH minimum capacity is set to 20%, the
real appliance capacity is the appliance minimum capacity
plus 20% of the dierence between the maximum and mini-
mum capacity.
Adjust the CH Minimum Capacity using the LEFT or RIGHT
keys, then store the setting with the OK key.
Default: 0%
Absolute Max CH Setpoint limits the setpoint during a cen-
tral heating call.This setting can be used to prevent a user from

ing screen will be displayed in EZ Setup if the user attempts to
raise the setpoint above the Absolute Max CH Setpoint. The
Absolute Max CH Setpoint will be displayed on the outdoor
curve in EZ Setup if the user selects an outdoor curve which
goes above the Absolute Max CH Setpoint.
Adjust the Absolute Max CH Setpoint using the LEFT or RIGHT
keys to then store the setting with the OK key.
Default: 186°F
CH1 Max. Setpoint is the maximum setpoint for a CH1
heating call when an Outdoor Curve option is chosen in
Demand Type. CH1 Maximum Setpoint is the xed setpoint
for a CH1 heating call when a Setpoint option is chosen in
Demand Type.
Adjust the CH1 Maximum Setpoint value using the LEFT or
RIGHT keys, then store the setting with the OK key.
Default: 180°F
CH1 Min. Setpoint is the minimum setpoint for a CH1
heating call when an Outdoor Curve option is chosen in
Demand Type. This setting is not applicable when a Set-
point option is chosen in Demand Type.
CH1 Min. Setpoint must be set equal or below the CH1
max. setpoint.

CH Post Pump Time sets how long the central heating
circulators will continue to operate at the completion of a
heating call. Any call during the CH Post Pump Time will be
ignored until the post pump has completed. The CH Post
Pump Time feature allows the heat remaining in the appli-
ance at the completion of a call to be sent to the heating
system, which will improve the overall eciency of the sys-
tem.

or a 0- 10V Modulation Signal when the outdoor temperature ex-
ceeds the Warm Weather Shutdown Temperature setting.
Adjust the Warm Weather Shutdown Temperature value us-
ing the LEFT or RIGHT keys, then store the setting with the
OK key.
The Warm Weather Shutdown icon ( ) is displayed on the
home screen when the outdoor temperature reaches the
Warm Weather Shutdown Temperature.
Default: OFF.

The Freeze Protection menu allows the feature to be enabled
and disabled. The built-in frost protection mechanism activates
the system pumps as soon as the ow temperature [NTC1
probe] drops below 46°F. As soon as the ow temperature is at
42°F, the burner starts up until the ow temperature rises above
60°F. The pumps continue to run for around 10 minutes.
Select Enabled or Disabled using the UP or DOWN keys,
then store the setting with the OK key.
• Enabled –The Freeze Protection feature protects the in-
stallation from freezing at a predetermined system ow
temperature.
• Disabled – The Freeze Protection feature is disabled.
Only the pumps operate.
Default: Enabled
Frost Protection Setpoint allows to dene the outside air
temperature at which the anti-freeze function is activated
(only available if an outdoor temperature sensor is connected).
The pumps are activated when the outside temperature drops
below the threshold dened in this menu.
Adjust the Frost Protection Setpoint using the LEFT or
RIGHT keys, then store the setting with the OK key.
In order to enable the protection of the whole
system against freezing, all the valves of the
radiators and the convectors should be com-
pletely open.
Default: -22°F
CAUTION
The appliance should NEVER be installed in
a location where freezing could occur. Sub-
jecting the appliance to freezing conditions
could lead to freezing of the condensate pos-
sibly causing serious injury or death.
Freeze Protection should only be disabled
when the system contains antifreeze to pre-
vent the system from freezing. Serious damage
could occur to the appliance as well as the en-
tire heating system if Freeze Protection is dis-
abled without antifreeze in the system.

Parallel Shift allows the CH setpoint to be externally adjusted
when a Constant option is chosen in Demand Type. When a
Constant 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
Adjust the Parallel Shift Value using the LEFT or RIGHT keys,
then store the setting with the OK key.
Default: 0°F
CH Call Blocking sets the minimum time between burner
rings for central heating calls. At the completion of a burn-
er ring, the CH Call Blocking time will begin. The burner
will not re again until after the CH Call Blocking time has
elapsed. The CH Call Blocking time only prevents the burn-
er from ring, 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.
Adjust the CH Call Blocking value using the LEFT or RIGHT
keys, then store the setting with the OK key.
Default: 2 min.
