MENU ITEM DESCRIPTION
BOILER MODEL
• MUST be set to correct model.
• Check the boiler model against the model listed on the
boiler’s rating plate. Change the selection to the correct
model if not. Also verify the model number on the
Evergreen control display at power-up. Failure to correct
would result in severe personal injury, death or substan-
tial property damage.
CONTROL TYPE
• Select single, master or shadow. Must be set to Single for
basic mode.
HIGH ALTITUDE
• If the boiler is installed at an altitude above 5500
feet, select YES for high altitude. The control will automatically
adjust fi ring rates (blower speeds) to compensate for altitude.
Altitude MUST be set correctly to avoid risk of severe personal
injury, death or substantial property damage.
LP GAS
• MUST be correct — YES if LP Gas is used or NO
if natural gas is used. Follow screen instructions to change
if necessary.
ODT SENSOR
EXEMPT
• Select YES only if boiler is exempt from the requirement
for outdoor reset operation stipulated in Section 303 of
the 2007 Energy Act. See information provided elsewhere
in this manual.
MANUAL RESET
HIGH LIMIT TEMP
• 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.
WWSD TEMP
• WWSD stands for warm weather shut down. It
means the boiler will not be allowed to fi re if the out-
side 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.

The outdoor sensor must be installed to use this function.
ADJUST OUTDOOR
• Use this setting to calibrate the outdoor sensor when needed
to compensate for variations in lead length or other factors
that could affect total resistance in sensor circuit.
CIRCULATOR
EXERCISING
• For each circulator, select whether you want the control
to automatically start the circulator and run for 10 sec-
onds for each 72-hour period of inactivity.
FREEZE PROTECT
CIRCS
• This function automatically fi res the boiler at low fi re and
starts the circulators chosen if the heat exchanger sensors
detect a temperature less than 45 °F. Burner is turned on
if temperature drops below 40 °F. Circulators and burner
turn off when the temperature rises above 48 °F.
RESET FACTORY
DEFAULTS
• Use this function to restore all control settings to factory
default values — will require complete restart and setup
of control after resetting. Record information from
the MAINTENANCE screen and any history informa-
tion that may be of use in the future. ALL stored data is
eliminated when reset to defaults except for boiler model
number.
