Risk of failure to bring in outdoor air during occupied periods.
For units with electrically operated outdoor-air dampers, outdoor-air is only taken in during occupied
periods. Outdoor-air intake requires definition of occupied periods. Unless otherwise specified in the
submittal data, exhaust function (if any) requires definition of occupied periods.
Units are shipped with no occupied periods defined.
Some units may use an internal seven-day time clock controlling the intake of outdoor air during Occupied
periods. In this case the times of the occupied periods must be set as shown here.
NOTE: The clock is based on 24-hour (military) time. See Startup - Set Internal Clock, first page previous.
If asked for a password, enter 1793 for units made before April 2005. For units made since April 2005, enter 17
or 1793.
NOTE: In the images and the discussion,
“aa”, “bb”, “cc”, “dd”, “ee”, “gg”, “hh”, “ii”,
“kk”, “nn”, “pp”, and “rr” are placeholders.
Your screen will actually show the current
values for your unit.
NOTE: Units ship with all values set to 00.
This means that no outdoor air will be
brought in until occupied periods are
defined, as shown on this page.
