Outdoor
Temperature Sensor
The boiler comes equipped with several outdoor reset curves, which are different target
temperature lines dependent on the outdoor temperature. The selected curve should be based off
of the type of heat emitter and the target temperature desired. The steeper the curve (higher the
value) the quicker the system will come up to temperature. The high temperature curve is default.
It is recommended to use this for all applications except in-floor/slab radiant.
