switch placed in the CAL position. If the control is power cycled in
this condition, the factory program will overwrite the existing
running program. If in the LOAD FIRMWARE menus, STORAGE
LOCATION 0 will be an allowed storage location.
When set to DUAL FUEL, input T3/ RESERVED, OPTION input
is used to control the DUAL FUEL OPTION relay via K8 contacts
on J4.2 &.6. When set to NO OPTION the input T3/RESERVED,
OPTION relay K8 on J4.2 &.6 is inactive.
When set to BASE LOAD, the Option Relay K8 on J4.2 &.6 is used
as an enable contact for a base load boiler. The J4.1 &.5 0-10vdc/4-
20mA output is used to modulate the base load relay if it is of the
modulating type.
The limitation of the OPTION menu is that Dual Fuel cannot be
used with a Base Load boiler.
The product type allows configuration of the control for a product
(and given a personality). This allows the control to be
used/interchanged with many products. The following fields will be
adjusted for the personality of the product.
This defines a boiler as condensing or non-condensing.
This is the BTU input rating of the boiler. This value is not used
with this released version and is displayed only for reference. Future
releases may incorporate this feature. Check the revision history
sheet on the website.
This is the blower type associated with the product. This should not
be changed manually. Due to earlier models of KNs using Variable
Frequency Drives, this setting needs to be adjusted for Whirlwind
(Ametek) models. The default is for a VFD.
This defines the mass of the boiler. This value is not used with this
version and is displayed only for reference and future applications.
Check the revision history sheet on the website.
This is the turndown of the boiler. For the KN-series the default is
5:1 and determines the minimum firing percentage. 5:1 = Min 20%,
4:1 = Min 25%, 3:1 = Min 33%.
NOTE: The boiler must be set up for operation at this Turndown
rate using the Calibrate settings. This TURNDOWN setting only
controls the displayed percentage.
This is the Altitude in feet of where the boiler is installed. On
Ametek Blowers it limits the blower output for low altitudes and
allows a higher output at higher altitudes. This setting sets the upper
range limit of the MAX VFD setting.
