OPERATING INFORMATION
The Prestige SOLO boiler is controlled by the MCBA
Control module, which is a microprocessor electronic
controller. The MCBA offers various control options
which may be adjusted to the various installation appli-
cations to achieve optimum boiler efficiency and func-
tion.
The MCBA module has the capability to sense the
boiler supply and return water temperature, the flue
gas temperature, the outdoor temperature and the
storage temperature of a SMART / TR Series IDWH or
optional DHW kit (when optional NTC is installed).
The MCBA uses this information to regulate the boil-
er’s on/off operation and modulate the input rate of the
boiler to closely match the required demand of the
heating system.
PROGRAM ACCESS OF THE MCBA
To adjust the factory parameter settings of the Prestige
MCBA the installer must enter into the parameter listing
of the MCBA.
Do not attempt to adjust or revise any parameter
settings except those listed in detail throughout
this manual. A complete listing of factory set-
tings are listed on Page 26 at the end of this
manual if there is doubt or concern that a wrong
setting was revised. Failure to comply could
result in erratic or unreliable operation of the
Prestige boiler.
To enter the parameter listing of the MCBA control, the
installer must enter the activation code as follows:
1. Press and hold the MODE button
2. Continue holding the MODE and press STEP button
until STBY appears and hold both STEP and
MODE buttons for 2 to 3 seconds.
The display should read CODE
3. Release the STEP and MODE buttons on the con-
trol panel.
4. Press STEP once.
WARNING
The display should read C_ XX (XX should be
a random number from 00 to 99)
5. Press the + or - button to change the display num-
ber
C_ XX to read C_05 . Press and release the +
or - to change the display one number at a time.
Press and hold the + or - to rapidly change the dis-
play number.
6. When the display reads C_05 press STORE to
save the activation code. The display
C_05 should
flash when the code is entered and saved.
After the activation code is entered press the MODE but-
ton until the display shows
PARA . At this point the
installer can access the parameters required for appli-
cation.
Once in the parameter mode, press the STEP repeated-
ly to reach the appropriate parameter setting. The dis-
play should show the following sequence, as the STEP
button is press repeatedly:
Press STEP once- 1140
Press STEP x2 - 2_01
Press STEP x3 - 3_01
Press STEP x4 - 4186
Press STEP x5 - P_05
Press STEP x6 - P_06
Etc......
After Parameter 4 the display will continue to show P fol-
lowed by a two-digit number that increases with each
press of the STEP button.
The actual parameter values displayed on the
unit may vary depending on the application. The
parameter sequence will always occur in the
order shown.
Once a particular parameter sequence is reached,
release the STEP button. Wait a second and the display
will show the current setting for that parameter in the
right two display digits.

To Change a Parameter Setting
Use the + or - button to change the value on the
display.
Press the STORE button once to save the
change. The display should flash to indicate the
new value is stored.
If a parameter setting is changed from the facto-
ry default and the STORE button is not pressed
to save the setting, the MCBA module will auto-
matically store the setting after 15 minutes.
Ensure all parameters settings are either factory
default or revised based on the application.
Review all parameters settings using the work-
sheet on page 26 when completed and prior to
commission of the boiler. Failure to comply
could result in erratic or unreliable operation of
the Prestige boiler.
Once a parameter setting value has been
revised and stored, if the STEP button is
pressed for the next parameter setting the value
setting of that parameter will appear. The dis-
play will not show P_XX of the next sequential
parameter. The sequence of parameters may be
scrolled through, as the display will roll over
from parameter 42 to parameter 1.
If sequential parameters are being revised and since
the display will not show P_XX of the next sequen-
tial parameter, it is recommend to press and hold
the STEP button to scroll through the entire list of
parameters before making any additional changes
to avoid any potential confusion.
To exit the Code mode press the RESET button
once.

REVISING APPLICATION SETTINGS
The following sections in this manual cover various
parameters settings within the MCBA control that can be
revised based on the particular application in which the
Prestige is installed. The parameter settings may be
combined to provide the optimum application perform-
ance of the Prestige.
The installer should record each revision using the work-
sheet located page 26 in the back of the manual as the
parameter changes are being made. Prior to changing
any parameters the installer should determine what the
application requirements are and determine which
parameter revisions are needed.

DOMESTIC HOT WATER APPLICATIONS
In all domestic hot water applications the Prestige boiler
will provide a domestic priority feature in which the CH cir-
culator will be blocked from providing heated water to the
space heating zones during a domestic hot water demand.
This feature cannot be adjusted or eliminated from the
MCBA program.
DOMESTIC HOT WATER (SMART/TR
SERIES OR DHW KIT) WITH NTC SENSOR
This application requires the optional NTC sensor kit for
SMART/TR Series Indirect Fired Water Heaters or for
DHW kit. In this application the NTC sensor will monitor
the domestic water storage temperature of the IDWH.
The domestic water storage temperature will determine
the ON/OFF operation of the boiler and the modulation
input of the boiler.
Parameter Adjustments
The first parameter adjustment needed for this applica-
tion is Parameter 35, which sets the MCBA control to
accept the NTC sensor of the IDWH. Follow the steps
given in Program Access Section on page 2 until the dis-
play shows P_35 . Release the STEP button and dis-
play should show the factory setting listed below. Use
the + or - to adjust to the revised setting listed below and
press STORE to save the setting. The display setting will
flash when the setting is stored within the MCBA control.
Parameter 35 has multiple parameter settings
available in addition to the settings 12 and 13. DO
NOT set Parameter 35 to any other setting other
than 12 or 13. Failure to comply can result in errat-
ic or unreliable operation of the Prestige Boiler.
The next parameter adjustment for this application is
Parameter 1, which is accessible during normal opera-
tion and does not require entry into the CODE mode. To
exit the CODE mode, press the RESET button once.
Parameter 1 is the set point temperature for domestic
water storage in the IDWH. The heat request for domes-
tic heating is based on this parameter setting. To adjust
WARNING
the parameter setting press MODE until display shows
PARA . Press STEP once and the display should show
factory setting 1140 . Use the + or - to adjust the setting.
Press STORE to save the setting. The display will flash
when the setting is stored into the MCBA control.
If Parameter 1 is set below 134ºthen it is recommended
that Parameter 33 be reset to a higher setting. The
request for heat is based on the temperature reading of
the DHW NTC sensor and its relationship to Parameter
1. The operating temperature setpoint of the boiler is
based on Parameter 1 + Parameter 33 with a maximum
operating temperature of 194ºF. The burner ON/OFF
and modulation is based on the relationship of the boiler
supply temperature and the sum of Parameter 1 and
Parameter 33.
To adjust the DHW Set Value Addition follow the steps
given in Program Access Section on page 2 until the dis-
play shows
P_33 . Release the STEP button and the
display should show the factory setting. Use the + or -
to adjust to the revised setting and press STORE to save
the setting. The display setting will flash when the set-
ting is stored within the MCBA control
Error Codes
If Parameter 35 is set to 12 and no NTC sensor is con-
nected to the 24 volt terminal strip, DHW T-T connection
on the Prestige, then a “soft” lockout will occur. The dis-
play will show an error code of
b_38 alternating with a
status code of 9.
If Parameter 35 is set to 12 and the NTC for DHW is
short-circuited then a “soft” lockout will occur. The dis-
play will show an error code of b_33 alternating with a
status code of 9.

During these “soft” lockout conditions the burner function
is blocked for DHW as well as CH request for heat. Only
the CH circulator will respond to a request for heat.
Both error codes will reset automatically when the error
condition is corrected.
During any DHW error condition the Prestige will
continue to maintain normal CH circulator oper-
ation on a CH request for heat, but will block the
burner function for a CH request for heat. The
Prestige will block the burner and DHW circula-
tor operation on a DHW request for heat until the
error condition is corrected.
DHW NTC SENSOR DIFFERENTIAL
The MCBA module has 2 differential settings for the
burner operation when using a NTC for DHW applica-
tions. The first differential setting is Parameter 26
“Detection ON”. This parameter sets the DHW storage
temperature low limit. The burner operation will respond
when the DHW storage temperature drops below the
Parameter 1 setting minus the Parameter 26 setting.
A minimum “Detection ON” parameter setting will create
a quick burner operation response to any domestic
water draws from the storage tank. In contrast, a maxi-
mum “Detection ON” setting will result in a delay
response to domestic draws.
NOTICE
The “Detection ON” setting of Parameter 26
greatly affects the production of domestic hot
water. A minimum setting of Parameter 26 could
result in rapid responses to a DHW request for
heat resulting in a potential scald hazard. It is
strongly recommended that the installer utilizes
a thermostatic mixing valve on the hot water out-
let of the DHW storage tank. Failure to comply
could result in severe personal injury, death or
substantial property damage.
Parameter Adjustments
To adjust DHW NTC sensor differential “DETECTION
ON” value follow the steps given in the Program Access
Section on page 2 until the display shows P_26 .
Release the STEP button and the display should show
the factory setting. Use the + or - to adjust to the revised
setting and press STORE to save the setting. The dis-
play setting will flash when the setting is stored within the
MCBA control.
The second differential setting is Parameter 27
“Detection OFF”. This parameter sets the DHW storage
temperature high limit. The burner operation will cease
when the DHW storage temperature rises above the
Parameter 1 setting plus Parameter 27 setting.
A maximum “Detection OFF” parameter setting will result
in an extended burner firing cycle when responding to
any domestic water draws from the storage tank. This
extended burner firing cycle could result in a final stor-
age temperature of the domestic hot water that is higher
than the desired storage temperature setting.

Parameter Adjustments
The first parameter adjustment for IDWH aquastat con-
trol application is Parameter 35. Follow the steps given
in Program Access Section on page 2 until the display
shows P_35 . Release the STEP button and thedisplay
should show the factory setting list below. Use the + or
- to adjust to the revised setting and press STORE to
save the setting. The display will flash when the setting
is stored in the MCBA control.
Parameter 35 has multiple parameter settings
available in addition to the settings 12 and 13. DO
NOT set Parameter 35 to any other setting other
than 12 or 13. Failure to comply can result in
erratic or unreliable operation of the Prestige
Boiler.
The next parameter adjustment for this application is
Parameter 1 and Parameter 33. Parameter 1 is acces-
sible during normal operation and does not require entry
into the CODE mode. To exit the CODE mode, press
the RESET button once.
Parameter 1 and Parameter 33 combine to create the
boiler operating temperature limit during a heat request
for DHW. The operation of the burner on/off is con-
trolled by the IDWH aquastat. The modulation of the
burner is based on the current boiler temperature and
its relationship to the temperature limit established by
Parameter 1 plus Parameter 33.
If Parameter 1 is set below 134ºF then it is recom-
mended that Parameter 33 be reset to a higher setting.
The request for heat is based on the DHW aquastat
closing an end switch which is connected directly to the
24V low voltage terminal of the Prestige. The operating
temperature set point of the Prestige boiler is based on
Parameter 1 + Parameter 33 with a maximum operating
temperature of 194ºF. The burner modulation is based
on the relationship of the boiler supply temperature and
the sum of Parameter 1 and Parameter 33.
WARNING
The “Detection OFF” setting of Parameter 27
greatly affects the production of domestic hot
water. A maximum setting of Parameter 27 could
result in excessive domestic storage tempera-
ture resulting in a potential scald hazard. It is
strongly recommended that the installer utilize a
thermostatic mixing valve on the hot water out-
let of the DHW storage tank. Failure to comply
could result in severe personal injury, death or
substantial property damage.
To adjust DHW NTC sensor differential “DETECTION
OFF” value follow the steps given in Program Access
Section on Page 2 until the display shows
P_27 .
Release the STEP button and the display should show
the factory setting. Use the + or - to adjust to the revised
setting and press STORE to save the setting. The dis-
play setting will flash when the setting is stored within the
MCBA control
FROST / FREEZE PROTECTION OF THE
IDWH
This feature is only available when the storage tank tem-
perature is controlled by a NTC sensor. If the NTC sen-
sor senses a domestic storage tank temperature of 38ºF
then the Prestige will active the DHW burner and circu-
lator function. The burner will operate at minimum input
rate and the circulator will energize until the NTC sensor
senses 50ºF. At that point the boiler will shut off the
DHW burner function and DHW circulator. This feature
is always active even if the DHW operation is placed into
an OFF mode (See Parameter 2 DHW Burner /
Circulator Function Setup, page 9).
DOMESTIC HOT WATER (SMART OR TR
SERIES) WITH AQUASTAT CONTROL
This application is the standard factory setup of the
MCBA control. In this application the Prestige uses the
aquastat of the SMARTor TR Series Indirect Fired
Water Heaters to initiate a request for heat.

Error Codes
If Parameter 35 is set to 12 (DHW - Storage Tank with
NTC Sensor) and a DHW aquastat is connected to the
Prestige 24 volt terminal strip connections for DHW, then
a “soft” lockout will occur. The display will show an error
code of
b_33 or b_38 alternating with a status code of
9 depending on the status of the aquastat.
The error code display on the Prestige will
switch from error code b_33 to error code b_38
if the IDWH aquastat is adjusted from a “closed”
to “open” position. The error code display on
the unit will not switch from an error code b_38
to an error code b_33 when the aquastat is
adjusted from an “open” to “closed” position.
DHW BURNER / CIRCULATOR FUNCTION
SETUP
The type of DHW/boiler operation can be revised to the
application requirements. The Prestige offers 4 different
DHW/Boiler Function setup modes. Those function
setups are defined as:
-OFF In this mode the Prestige will NOT recognize
any request for a “call for heat” from a DHW aquas-
tat or NTC sensor. This mode shuts down the DHW
NOTICE
operation, both burner and DHW circulator function,
of the Prestige control. The Prestige will maintain
all CH operation, both burner and CH circulator
function, with no domestic priority in this mode.
-ON In this mode, factory setting, the Prestige burn-
er and DHW circulator will operate in a response to
a “call for heat” by the IDWH. This request can be
either a NTC sensor or DHW aquastat. There is
domestic priority over central heating in this mode.
-OFF + Pump Continuous In this mode of opera-
tion the Prestige will block the burner operation dur-
ing a request for “call for heat” from a NTC sensor
or DHW aquastat. The DHW circulator will remain
energized at all times even during a CH request for
heat. The Prestige will maintain all CH operation,
both burner and CH circulator function, with no
domestic priority feature.
-ON + Pump Continuous The Prestige will main-
tain continuous circulation on the DHW circulator
and will provide burner function when a request for
heat is generated by the NTC sensor for DHW or by
the DHW aquastat. The Prestige will provide
domestic priority by blocking the CH circulator func-
tion during a DHW request for heat.
When determining the type of DHW operation,
especially those applications with continuous
pump feature the installer should install a ther-
mostatic mixing valve on the outlet of the
domestic tank to prevent a potential scalding
hazard. Failure to comply could result in a
scalding hazard causing severe personal injury,
death or substantial property damage.
Parameter Adjustments - OFF Mode
The parameter adjustment to set the DWH operational
option to OFF can be done either through the STBY
mode during normal operation or by entering into the

PUMP SETUP
At the completion of a DHW request for heat the amount
of time for post pump activity can be determine. The
post pump feature allows the stored heat within the boil-
er to be absorbed in the Domestic Tank, thus preventing
any potential overheating of low temperature space
heating applications.
When utilizing and adjusting the allowable time
for DHW post pump activity it is strongly recom-
mended that a thermostatic mixing valve with
anti-scald feature be installed on the hot water
outlet of the domestic tank. Failure to comply
could result in a scalding hazard causing severe
personal injury, death or substantial property
damage.
Parameter Adjustments
The parameter adjustment for DHW post pump activity is
Parameter 21. Follow the steps given in Program
Access Section on page 2 until the display shows P_21 .
Release the STEP button and display should show the
factory setting. Use the + or - to adjust to the revised
setting and press STORE to save the setting.
The parameter setting is multiplied by 10.2 sec-
onds for the actual setting. For example the fac-
tory setting is 3 and the actual time period of the
post pump cycle is 30.6 seconds.

DOMESTIC HOT WATER APPLICATION -
DHW REQUEST FOR HEAT SETUP
At the completion of a DHW request for heat, the amount
of time for delay in reacting to a secondary DHW request
for heat can be determined. The “blocking” time feature
prevents potential short cycling of the boiler burner and
extends the life of the blower/ burner components.
During the blocking period the burner will not fire in
response to a secondary DHW. Only the DHW request
for heat circulator will begin circulating at the start of the
secondary DHW request for heat.
Long “blocking” time will effect the production of
domestic hot water and can result in the lack of
domestic hot water delivery for the application.
Parameter Adjustments
The parameter adjustment for DHW “blocking” time is
Parameter 29. Follow the steps given in Program Access
Section on page 2 until the display shows P_29 .
Release the STEP button and display should show the
factory setting. Use the + or - to adjust to the revised
setting and press STORE to save the setting.
The parameter setting is multiplied by 10.2 sec-
onds for the actual setting. For example if the
parameter setting is 03 and the actual time peri-
od of the “blocking” time is 30.6 seconds.

DOMESTIC HOT WATER APPLICATION -
DHW TO CH REQUEST FOR HEAT SETUP
At the completion of a DHW request for heat, the amount
of time for burner delay in reacting to a CH (space heat-
ing) request for heat can be determined. The “blocking”
time feature in conjunction with the DHW post pump
cycle may prevent any potential overheating of a low
temperature CH system. This blocking time period does
not affect the production of domestic hot water.
If the parameter setting is 00 (OFF setting for this func-
tion feature) and the burner is firing at the completion of
a DHW request for heat, then the burner will remain fir-
ing and the CH circulator will begin pumping. If there is
a blocking time setting, the burner will shut down for that
period, while the CH pump will circulator to the system.
Long “blocking” times may affect the comfort
level of the occupants in certain CH zones.
Parameter Adjustments
The parameter adjustment for DHW to CH “blocking”
time is Parameter 30. Follow the steps given in Program
Access Section on page 2 until the display shows
P_30 . Release the STEP button and display should
show the factory setting. Use the + or - to adjust to the
revised setting and press STORE to save the setting.
The parameter setting is multiplied by 10.2 sec-
onds for the actual setting. For example if the
parameter setting is 03 and the actual time peri-
od of the “blocking” time is 30.6 seconds.
A 00 setting of this parameter places the feature
in an OFF condition.

CH APPLICATION FUNCTION SETTING -
OUTDOOR TEMPERATURE
The CH operating temperature is controlled and estab-
lished by the use of an outdoor sensor measuring the
outdoor temperature. In this application the Prestige can
maintain constant flow through the system and maintain
a constant request for heat. The burner function is
based on the outdoor temperature reading and its rela-
tionship to the maximum and minimum allowable oper-
ating temperature in Parameters 4 and 5. This applica-
tion requires the use of a 12k NTC sensor, reference
Triangle Tube’s Outdoor Sensor Kit, connected to the
appropriate 24V terminals on the Prestige.
The use of a room thermostat is not required typ-
ically in this application. The room thermostat
has no control over the CH burner function or
the CH circulator function. The room thermostat
does provide other application options such as
Parallel Shift / Night Setback.
To operate the Prestige under this application mode sev-
eral Parameters must be revised to establish the
required operating temperatures for the application. To
configure the MCBA control to react based on the out-
door temperature, Parameter 34 must be revised
accordingly and any corresponding parameters will be
defined in detail in later sections.

In this application mode the domestic priority
function will remain, resulting in the CH circula-
tor being blocked and the boiler operating tem-
perature will reset to Parameter 1 plus Parameter
33.
Parameter Adjustment
The parameter adjustment of Parameter 34 in the CODE
mode is done by following the steps given in Program
Access Section on page 2 until the display shows
P_34 . Use the + or - to adjust to the revised setting,
listed below and press STORE to save the setting.
To control the burner and CH circulator function when in
this Heat Request - Outdoor Sensor mode the installer
has 2 options:
-Option 1 is to install a summer / winter switch in
parallel to the outdoor sensor on the 24 volt ter-
minals. The switch would create a false outdoor
temperature that would block the CH burner and
CH circulator function. Domestic hot water
would remain functional and would respond to
any request for heat from the IDWH.
-Option 2 is to reference the section on Burner
Blocking Temperature and revise the parameter
setting accordingly.
It is important that the installer references the
section regarding the Burner Blocking
Temperature. The consideration and implemen-
tation of this operating feature will prevent the
need of a summer / winter switch.

TO 10V EXTERNAL CAPACITY WITH AM4
INTERFACE
This application is generally for multiple boilers in which
there is an external boiler control to stage the boilers and
control the burner modulation. In this application the
external controller will control the burner modulation
based on the system load requirements.
The external controller will provide a 0 to 10V analog
input to the Prestige AM4 interface module based on the
time to meet the system load requirements. The initial
analog input of 1.8V or less will indicate the minimum
load. An analog input of 10V will indicate the maximum
load requirements. The actual function of the external
controller will vary from manufacturer to manufacturer.

to meet the load requirements. An analog input of 0V
will indicate the minimum system temperature of 32ºF
and an analog input of 10V relates to a maximum sys-
tem temperature of 212ºF. Because these tempera-
tures are outside the normal operating limits of the
Prestige, the minimum and maximum system tem-
perature must be set using Parameter 4 and 5. The
actual function of the external controller will vary from
manufacturer to manufacturer.
To operate the Prestige under this application mode,sev-
eral parameters must be revised to establish the
