NOTICE
User’s Information Manual
Adjusting parameters
CAUTION
Before changing parameters, note the
settings so that the unit can be returned to
its original operating parameters.
The control uses an internal clock for the night setback feature
and for logging of events. For these features to work properly,
the clock must be set when the boiler is first installed or any
time the boiler has been powered off for more than four (4)
hours. This parameter must be accessed to set the clock.
NOTICE
The internal clock does not adjust for
Daylight Savings Time and therefore,
will require a manual adjustment.
To set the clock, access the clock menu as described in the
User section. Rotate the NAVIGATION dial (if needed) until
the arrow (>) is pointing to “TIME & DATE”. Press the
NAVIGATION dial once. If the date and time are incorrect,
press the NAVIGATION dial again. The hours value will
begin flashing. Rotate the NAVIGATION dial until the hour
and AM/PM values are correct. Press the NAVIGATION
dial again. The minutes value will begin flashing. Rotate
the NAVIGATION dial to adjust the minutes. Repeat this
procedure to adjust the month, date and year. Save the
new settings as described in the Saving Parameters section
(this page).
