AUTO = Local/ System/ WWS Setpoint is used
4-20mA input is mapped to a setpoint.
OUTDOOR AIR RESET
OA RESET
OFF
Outdoor reset ratio (boiler water temp/outside air temp).
WARM WEATHER SD
NO
If set to YES, the boiler /system shuts down when the
temperature exceeds the WWS SETPOINT.
WWS SETPOINT

°
F
(40 – 100
°
F)
Temperature at which boiler shuts down, operation is below
this.
If boiler is running using either OA RESET or WWS and the
OA OVR input is closed the OA RESET slope is overridden
and runs at local setpoint until OA OVR input opens.
SET OA SETPOINTS

Boiler water temp setpoint when OA temp is at HIGH
OATEMP These four setpoints determine the OA reset
slope.
