SMART SYSTEM control module
A: General
Boiler model
The control will display “Knight Boiler” as the model number
because the same control is used on several models. This will
be displayed when parameter
A1
has been accessed. This
parameter is not changeable.
User code
The User Code allows the user to access and change a limited
number of control parameters.
The access code can be
changed by the user or the installer to a code of their
choosing.
To change the code, parameter
A2
must be
accessed. The default code is 0704. The code can be changed
one digit at a time by using the arrow keys on the display.
Time and date
The control uses an internal clock for the night setback
feature and for logging of events. For these features to work
correctly, the clock must be set when the boiler is first
installed or anytime the boiler has been powered off for more
than 30 days.
To set the clock, parameter
A3
must be
accessed. The date and time are displayed as “YY:MM:DD W
hh:mm”. YY = year, MM = month, DD = date, W = day (1 =
Sunday, 2 = Monday, etc.), hh = hour (24 hour time;
2:00 PM = 14:00), mm = minutes.
Software version
The software version allows the user to view the software
version in use by the control. This software controls the
operation of the boiler.
When a new software version
becomes available, the existing control can be replaced with a
new control to update the software.
Unit °C or °F
The control can be configured to display temperature in
either °C or °F. This parameter can be changed by the user or
the installer by accessing parameter
A5
. The default is °F.
Night setback temperature
Once the internal clock has been set correctly, the night
setback feature can be used to program a lower water
temperature set point for space heating. This parameter can
be changed by the user or the installer by accessing parameter
A6
. The temperature range for this parameter is 32°F to
140°F. The feature is turned off with a setting of 32°F. The
default value is 32°F.
Night setback times
If parameter A6 is set to anything other than 0°F, the night
setback feature becomes active. This will require start and
stop times to be programmed for the days that reduced
temperatures are required. These times can be changed by
the user or the installer by accessing parameter
A7
. Each day
of the week (Sunday through Saturday) will have an on and
off time.
Example:
Monday ON: 22:30, Tuesday OFF: 6:45. If you
wish to skip a day and have no night setback, leave the on and
off times the same. The default times for each day will be
00:00 (midnight).
B: Temperature settings
SH set point user
The SH set point user sets the water temperature set point for
fixed operation or the maximum temperature set point when
the outdoor air sensor is used.
This parameter can be
changed by the user or the installer by accessing parameter
B1
. The temperature range of this parameter is 50°F to 190°F.
The default value is 125°F.
C: Data logging
SH hours running
The SH hours running parameter shows the total number of
hours the boiler has been in the SH firing position. This
parameter can be viewed by the user and the installer by
accessing parameter
C1
.
DHW hours running
The DHW hours running parameter shows the total number
of hours the boiler has been in the DHW firing position. This
parameter can be viewed by the user and the installer by
accessing parameter
C2
.
Burner starts
The burner starts parameter shows the total number of times
the boiler has attempted to fire. This parameter can be
viewed by the user and the installer by accessing parameter
C3
.
Show last 10 errors
The control will log the 10 most current errors with the date
and time the error occurred. This parameter can be viewed
by the user and the installer by accessing parameter
C4
.
