Boiler capable of operating in Outdoor Reset Mode when
included Outdoor Sensor is connected and proper CH Mode
selected.
If CH Mode = 1, ‘Outdoor Temperature Reset with Thermo-
stat’ or 2, ‘Full Outdoor Reset’ boiler will adjust CH set point
proportional to outdoor temperature as defi ned by Outdoor
Reset Curve below.
Outdoor reset curve adjusted by modifying Design and Mild
Weather reference temperatures. See points A & B of Reset
Curve below.
Calculated CH set point always limited between ‘Reset Curve
Boiler Minimum/Maximum’ temperatures. See points C & D
of Reset Curve below.

Note:
Modes only function when outdoor temperature sensor
•
connected.
If ‘Open’ outdoor sensor detected CH set point equal to
•
‘Boiler Reset Curve Design’ temperature.
Outdoor temperature used for CH set point calculation
•
measured once a minute and averaged with
previous measurement to compensate for rapid outdoor
temperature variations.
