Outdoor reset curve adjustment
(K-Factor)
NOTE: If set to RC mode, adjusting this
value will not have any effect on the
controller or boiler.
This button adjusts the relation of boiler
temperature to outside temperature. Ideally
the slope should create an intersection
between maximum boiler temperature and
outdoor design temperature (climate zone
temperature)
Example: If outdoor design temp is 14°F and
max boiler supply is set to 122°F (perhaps
for in-floor heating), a value of 1.00 should
be entered here.
If the user wants to adjust this (because the
area does not seem to heat well) it should be
done in increments of 0.10 every 2 days to
allow the boiler time to adjust to the changes.
