Calibration
The calibration of the KN-Series boiler
should only be performed by a
licensed technician
.
All calibration settings should be adjusted based on the
boiler’s parameters. See the Boiler Installation, Operation,
and Maintenance manual (IOM).
To enter the calibration menus, place the S2 switch on the
main control board to the CAL position. A reloading
message will be displayed and then the Calibrate screen.
Be sure to set this switch back to NORM when the
calibration is complete, otherwise no external control inputs
will work (except T1-T2), the display will always indicate
CALIBRATE and some of the runtime temperatures will
not be displayed.
The
MINIMUM %
setting, the
MAXIMUM %
setting,
and the
IGNITIAN %
setting can be adjusted in the
calibration displays. The values can be changed while
running but,
ONLY IN MINIMUM FIRE
(any, but only one
of the T inputs closed or S1 in Low Fire). Prior to ignition,
the values may be changed, but the blower will not operate.
The Low Fire Hold switch (S1) is located
near the Calibration switch (S2).
While in Standby (no call for heat on any inputs), the
minimum percent may be pre-set. To set the minimum rate
while running, slide the “Low Fire” switch S1 or close any
(1), and only (1) of the (T) inputs in order to set the boiler to
MINIMUM fire.
To adjust the MININIMUM % as shown in the display,
press the Adjust button under the Minimum setting. The
percentage value will turn green. Adjust the Minimum value
to the desired setting using the arrow keys. The Minimum
setting is clamped to its lowest rated setting and cannot be
adjusted below this.Press the “check key”
once you are
done to save the setting or the “X key”
to throw out the
setting.
To adjust the IGNITION value as shown in the display,
press the Adjust button under the IGNITION setting. The
percentage value will turn green. The Blower speed will be
set here to provide the rate for ignition. While in Standby
(no call for heat on inputs), the Ignition percent may be
preset, before firing the boiler. To set the ignition rate while
running slide the “Low Fire” switch S1 to “Low Fire” or
any (1), and only (1) of the T inputs must be closed Pressing
the Adjust key here will cause the IGNITION setting to turn
green and the boiler will ramp to the ignition setting. Adjust
it using the arrow keys and then press “check key”
to
save the value. Press the “X key”
to discard the setting.
The Maximum % value is used to set the maximum fire rate
of the boiler. While in Standby (no call for heat on any
inputs), the Maximum percent may be pre-set.
The Maximum % of the boiler can also be set while
running. Close both of the (T) inputs T1 and T2 or slide the
“Low Fire” switch S1 to Low Fire and close one of the (T)
inputs, T1 or T2 to set the boiler to MAXIMUM fire.
To adjust the Maximum fire rate of the boiler, press the
Adjust button under the Maximum (%) value shown in the
display. The percentage value will turn green. Then use the
arrow keys to adjust the value up or down. After the
adjustment is completed, press the green “check key”
to
save the value. Press the “X key”
to discard the setting.
