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.
