Adjusting parameters

Time and date

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.  

 

CAUTION

Before changing parameters, note the 
settings so that the unit can be returned to 
its original operating parameters.

 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
