Setup wizard
Th
e Noble Combi Boiler control has a Setup Wizard feature
that can be used to help with the initial start-up of the unit.
Th
is Setup Wizard will walk an installer through the most
commonly required parameters.
Th
e Setup Wizard is automatically accessed the fi rst time the
unit is powered up from the factory and will allow setting
of certain parameters without the need to enter the installer
password. Once the Setup Wizard is completed or canceled,
it can only be accessed again by going through the Installer
Menu.

Parameters in the setup wizard
- TIME/DATE
- SPACE HEAT SETPT (COLDEST DAY)
• This is the space heating water temperature set
point that will be used in Space Heating Mode.
If outdoor reset is used, this parameter represents
the water temperature on the reset curve
corresponding to the coldest day outdoor
temperature. When outdoor reset is in use, if
outdoor temperature falls below the OUTDOOR
TEMP COLDEST DAY parameter, space heating
set point can go higher than this setting.
• Range: 68°F – MAX SH SETPT (185°F by default)
•
Default:
125°F
-
MAX SH SETPT
- SPACE HEAT SETPT (COLDEST DAY)
• Th
e MAX SH SETPT should be set to the highest space
heating water set point that can be used for the specifi c
space heating system. Th
is parameter is the upper limit
of what the user can adjust the SH SETPT (COLD DAY)
parameter to. Th
is parameter also serves as a limit of
space heat set point that can be generated by the outdoor
reset curve in the event that outdoor temperature falls
below the coldest day outdoor temperature setting.
• Range: 60°F – 190°F
•
Default:
185°F
-
OUTDOOR TEMP COLDEST DAY
• When outdoor reset is used, this is the outdoor
temperature used on the reset curve corresponding to the
SPACE HEAT SETPT (COLDEST DAY). Th
is parameter
should be set to the outdoor temperature used in the heat
load calculation for the cold design day.
• Range: -40°F – 75°F
•
Default:
10°F
-
OUTDOOR TEMP – WARM WEATHER
SHUTDOWN
• When the outdoor temperature rises above this
point, the control will block all space heating
demands (DHW demands will still be active).
Space heating operation will resume when outdoor
temperature falls 10°F below this point.
• Range: 32°F – 104°F
•
Default:
70°F
- AUTO RESET HI LIMIT
• When the outlet temperature exceeds the Automatic
Reset High Limit setting, automatic high limit
action occurs. Th
e boiler shuts down until the
outlet water temperature cools below 10°F under
this setting and a 60 second timer has elapsed. Note
that this setting applies to both SH and DHW
Modes.
• Range: 32°F – 200°F
•
Default:
200°F
- MAN. RESET HI LIMIT
• If the outlet temperature continues to increase aft er
automatic reset high limit action, the Manual Reset
High Limit action occurs when the outlet water
temperature exceeds this setting. Th
is will require
a manual reset before operation can resume. Note
