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).
