80 Is Default.
For temperatures below -40°F (-40°C), maximum heating flow temperature set point no longer
increases and curves on the graph become horizontal. Boiler set point will override sensor
setpoint.

1. 1K Ohm (1k Ω) Outdoor Temperature
Sensor Kit - BD710487302V
•
Use the Outdoor Sensor (OAS) Kit with Heating Only
or Combi Boilers.
• Wire Control to boiler M2 terminal strip, terminals 4 and
5 as shown.
• Install/locate Control follow supplied instructions with
sensor kit and Installation, Operation and Maintenance
Manual (IOM).
Setting “Kt” Climate Curve:
1.
Boiler automatically recognizes OAS sensor when wired to
M2 terminal block. Display changes to show current default
“
Kt
” value (80). Note display value.
2.
When operating in CH mode, boiler setpoint is determined
by the
Kt
value selected and actual outside air
temperature. Refer to applicable °F (or °C) chart, (pg. 30)
for setpoint information.
• Select
Kt
range which will satisfy the desired boiler
delivery temperature based on outdoor temperature
range expected for your location. For example: if you
need 176°F water when the outside temperature is 20°F
and colder, select 35 for your
Kt
setting.
•
To change”default”
Kt
value on boiler control use
or
CH Heating buttons.
• Restrict the upper limit of the
Kt
curve by using Parameter
P16 to set the maximum boiler water temperature. P16
Default is 176°F.
3.
When OAS is installed, pressing
or
buttons will
no longer display boiler CH setpoint temperature. It now
displays the
Kt
value which can range from 10 to 90.
4.
When scrolling has stopped, boiler will automatically
“SAVE” value as new
Kt
default value and automatically
return to CH mode when no
Kt
adjustment activity
is sensed.
Kt
values can be changed in +/- 1 point
increments.
5.
To return, to verify or change current
Kt
“default value,
depress one of the CH setpoint adjustment buttons (once),
or
, while in any heating or standby mode. Adjust
Kt
value to obtain desired comfort level.
