DESCRIPTION
• 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 num-
ber on the control display at power-up. Failure to
correct would result in severe personal injury, death
or substantial property damage.
• Select single, master or shadow. Must be set to Single
for basic mode.
• If the boiler is installed at an altitude above
5500 feet, select YES for high altitude. The control
will automatically adjust firing rates (blower speeds)
to compensate for altitude. Altitude MUST be set
correctly to avoid risk of severe personal injury, death
or substantial property damage.
• If boiler outlet water temperature exceeds this
temperature, the Control will shut down the boiler
and enter lockout. Changing this setting is NOT
recommended.
• 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.

The outdoor sensor must be installed to use this
function.
• 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.
• For each circulator, select whether you want the
control to automatically start the circulator and run
for 10 seconds for each 72-hour period of inactivity.
• This function automatically fires the boiler at low
fire 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.
• 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 information that may be of use in the
future. ALL stored data is eliminated when reset to
defaults except for boiler model number.
