HIGHLIMITTEMP
y If boiler outlet water temperature exceeds this tempera-
ture, the Evergreen control will shut down the boiler and
enter lockout. Changing this setting is NOT recom-
mended.
WWSDTEMP
y WWSD stands for warm weather shut down. It means
the boiler will not be allowed to fire if the outside
temperature is greater than the WWSD setting.
When the boiler is kept off because the outside tem-
perature is above WWSD, the graphic display will show
WWSD, and the boiler will remain in standby until the
outside temperature drops below WWSD temperature.
WWSD does not apply to DHW systems.
e outdoor sensor must be installed to use this function.
ADJUSTOUTDOOR
y Use this setting to calibrate the outdoor sensor when needed
to compensate for variations in lead length or other factors
that could aect total resistance in sensor circuit.

onds for each 72-hour period of inactivity.

tion that may be of use in the future. ALL stored data is
