Programming Operating Schedules — The
ComfortLink™ controls will accommodate up to eight differ-
ent schedules (Periods 1 through 8), and each schedule is
assigned 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
CONFIGURATION (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 val-
ue 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 min-
utes digits will start flashing. Use the same procedure to
display and save the desired minutes value.
6. The first schedule is now complete. If a second schedule
is needed, such as for weekends or holidays, scroll down
and repeat the entire procedure for period 2 (PER.2). If
additional schedules are needed, repeat the process for as
many as are needed. Eight schedules are provided.
SERVICE TEST
General — The units are equipped with a Service Test fea-
ture, which is intended to allow a service person to force the
unit into different modes of operation. To use this feature, enter
the Service Test category on the local display and place the unit
into the test mode by changing Service Test
→
TEST from OFF
to ON. The display will prompt for the password before allow-
ing any change. The deffault password is 1111. Once the unit
enters the Service Test mode, the unit will shut down all current
modes.
TEST — The TEST command turns the unit off (hard stop)
and allows the unit to be put in a manual control mode.
STOP — The STOP command completely disables the unit
(all outputs turn off immediately). Once in this mode, nothing
can override the unit to turn it on. The controller will ignore all
inputs and commands.
S.STP — Setting Soft Stop to YES turns the unit off in an
orderly way, honoring any timeguards currently in effect.
FAN. F — By turning the FAN FORCE on, the supply fan is
turned on and will operate as it normally would, controlling
duct static pressure on VAV applications or just energizing the
fan on CV applications. To remove the force, press ENTER
and then press the UP and DOWN arrows simultaneously.
The remaining categories: INDP, FANS, ACT.C, COOL,
and HEAT are sub-menus with separate items and functions.
