OPERATING INFORMATION
The Prestige Boiler is controlled by the MCBA Control
Module, which is an electronic microprocessor controller.
The MCBA offers many control options, which may be
adjusted for various applications to achieve optimum
boiler efficiency and operation.
The MCBA Control Module has the ability to sense the
boiler supply and return water temperatures, the flue gas
temperature, the outdoor temperature, and the domestic
water temperature in a SMART/TR Series Indirect Water
Heater with the optional IDWH Sensor Kit PSRKIT22.
The MCBA uses this information to regulate the boiler’s
on/off operation and to modulate the firing rate of the
boiler to closely match the required demand.
ENTERING MCBA ACCESS CODE
The installer must enter the MCBA Access Code to
adjust the advanced parameter settings of the MCBA.
The Access Code can be entered as follows:
1. Press the MODE button until the display shows
STBY
.
2. Press and hold the MODE and STEP buttons
together for 2 to 3 seconds until the display shows
CODE
.
3. Press the STEP button once and the display will
show
C_
XX
where
XX
represents a random num-
ber.
4. Press the “+” or “–“ buttons to change the number
displayed to read
C_54
. Press and hold the “+” or
“–“ button to rapidly change the number.
5. When the display reads
C_54
, press the STORE but-
ton to save the Access Code. The display should
flash to indicate that the Access Code was saved.
After the Access Code has been entered, the advanced
parameters can be accessed by pressing the MODE
button until the display shows
PARA
. Once the display
shows
PARA
, press the STEP button to reach the
appropriate parameter. The display should follow the fol-
lowing sequence:
Press STEP once-
1140
Press STEP x2 -
2_01
Press STEP x3 -
3_01
Press STEP x4 -
4186
Press STEP x5 -
P_10
Press STEP x6 -
P_11
Etc......
After Parameter 4, the display will show P followed by
the parameter number. Once a particular parameter is
reached, the display will change to show the current set-
ting of that parameter.
The actual parameter values displayed on the dis-
play may vary depending on the application, but the
sequence will always occur in the order shown.
Changing a Parameter Setting
1. Use the “+” or “–“ button to change the parameter set-
ting.
2. Press the STORE button to save the change. The
display should flash to indicate that the change was
saved.
3. Press the RESET button to leave the Access Code
mode.
If a parameter setting is changed but the STORE but-
ton is not pressed to save the setting, the MCBA will
automatically store the setting after 15 minutes.
Ensure all parameters are at their factory settings or
appropriately revised for the application prior to
commissioning the boiler. Failure to comply could
result in erratic or unreliable operation of the
Prestige boiler.
Once a parameter setting has been revised and
stored, pressing the STEP button will display the
setting of the next parameter without showing
P_
XX
. To avoid confusion, It is advisable to contin-
ue pressing the STEP button until Parameter 46 is
reached. The next press of the STEP button will
cause the display to roll over to Parameter 1.
Continue pressing the STEP button until the next
parameter to be adjusted is reached and revise the
setting.
