FT.ST ) if the building pressure deviates from the
Building Pressure Set Point ( BP.SP ). Periodically, at the rate set
by the Fan Track Learn Rate ( FT.TM ), the delta cfm is adjusted
upward or downward with a maximum adjustment at a given in-
stance to be no greater than Fan Track Max correction ( FT.AD ).
The delta cfm cannot ever be adjusted to be greater than or less
than the Fan Track Max Clamp ( FT.MX ).
Set Clock on VFD (If Installed)
The clock set mode is used for setting the date and time for the
internal clock of the VFD. In order to use the timer functions of
the VFD control, the internal clock must be set. The date is

SET on display screen and press ENTER (SOFT KEY 2).
The clock set parameter list will be displayed.

Programming Operating Schedules
The Comfort Link controls will accommodate up to eight dif-
ferent schedules (Periods 1 through 8), and each schedule is as-
signed to the desired days of the week. Each schedule includes
an occupied on and off time. As an example, to set an occupied
schedule for 8 AM to 5 PM for Monday through Friday, the
user would set days Monday through Friday to ON for
Period 1. Then the user would configure the Period 1 Occupied
From point to 08:00 and the Period 1 Occupied To point to
17:00. To create a different weekend schedule, the user would
use Period 2 and set days Saturday and Sunday to ON with the
desired Occupied On and Off times.
NOTE: By default, the time schedule periods are programmed for
24 hours of occupied operation.
To create a schedule, perform the following procedure:
1. Scroll to the Configuration mode and select CCN CON-
FIGURATION (CCN). Scroll down to the Schedule
Number ( Configuration

CCN

SC.OV=SCH.N ). If
password protection has been enabled, the user will be
prompted to enter the password before any new data is
accepted. SCH.N has a range of 0 to 99. The default value
is 1. A value of 0 is always occupied, and the unit will
control to its occupied set points. A value of 1 means the
unit will follow a local schedule, and a value of 65 to 99
means it will follow a CCN schedule. Schedules 2-64 are
not used, as the control only supports one internal/local
schedule. If one of the 2-64 schedules is configured, then
the control will force the number back to 1. Make sure the
value is set to 1 to use a local schedule.
2. Enter the Time Clock mode. Scroll down to the LOCAL
TIME SCHEDULE ( SCH.L ) sub-mode, and press
ENTER. Period 1 ( PER.1 ) will be displayed.
3. Scroll down to the MON point. This point indicates if
schedule 1 applies to Monday. Use the ENTER command
to go into Edit mode, and use the UP or DOWN key to
change the display to YES or NO. Scroll down through the
rest of the days and apply schedule 1 where desired. The
schedule can also be applied to a holiday.
4. Configure the beginning of the occupied time period for
Period 1 (OCC). Press ENTER to go into Edit mode, and
the first two digits of the 00.00 will start flashing. Use the
UP or DOWN key to display the correct value for hours, in
24-hour (military) time. Press ENTER and hour value is
saved and the minutes digits will start flashing. Use the
same procedure to display and save the desired minutes
value.
5. Configure the unoccupied time for period 1 ( UNC ). Press
ENTER to go into Edit mode, and the first two digits of the
00.00 will start flashing. Use the UP or DOWN key to display
the correct value for hours, in 24-hour (military) time. Press
ENTER and hour value is saved and the minutes digits will
start flashing. Use the same procedure to display and save the
desired minutes value.
