Control Configuration Checklist- Refer to check-
list CL- 1 for recording site specific unit control configurations.
Programming Operating Schedules -- The
ComJbrtLink TM controls wilt accomlnodate 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 offtilne. As an example, to set an
occupied schedule for 8 AM to 5 PM tbr 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 difl_em weekend schedule, the user
would use Period 2 and set days Saturday and Sunday to ON
with the desired Occupied On and Offthnes.
NOTE: By default, the time schedule periods are pro mmnlned
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_C_--x_CH.O=SCH.3_). It"
password protection has been enabled, the user will be
prompted to enter the password before any new data is
accepted. S(_/L.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 wilt follow a local schedule, and a value of 65 to 99
means it will tbltow 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 confimlred, then
the control will tbrce the number back to 1. Make sure the
value is set to 1 to use a bcal schedule.
2. Enter the Time Clock mode. Scroll down to the LOCAL
TIME SCHEDULE (S(_.L) sub-lnode, and press
. Period 1 (PER.l) will be displayed.
3. Scroll down to the MON point. This point iMicates if
schedule 1 applies to Monday. Use the _ com-
mand to go into Edit mode, and use the [] or [] 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.
Configure the beginning of the occupied time period for
Period 1 (OCC). Press _ to go into Edit mode,
and the first two digits of the 00.00 will start flashing. Use
the [] or [] keyto display the correct value for hours,
in 24-hour 0nilitary) time. Press _ and hour value
is saved and the minutes dints will start flashing. Use the
saane procedure to display and save the desired minutes
value.
5. Conllgnlre the unoccupied time for period 1 (UN{). Press
to go into Edit mode, and the first two digits of
the 00.00 wilt start flashing. Use the [] or [] key to
display the correct value for hours, in 24-hour (military)
time. Press _ and hour value is saved and the
minutes digits will start tlashing. 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 tbr weekends or holidays, scroll do,am
and repeat the entire procedure for period 2 (PER.2). It"
additional schedules are needed, repeat the process for as
many as are needed. Eight schedules are provided. See
Table 35 for an example of setting the schedule.
SERVICE TEST
The Service Test function can be used to verify proper oper-
ation of compressors, heating stages, indoor tan, outdoor finis,
power exhaust tans, economizer, and atann relay. Use of
Service Test is recommended at initial system start up and dur-
ing troubleshooting. See Table 36.
Sin:ice Test modeehas the following changes fiom nonnal
operation:
• Normal compressor timeguards and other staging delays
are reduced to 30 seconds or less.
• Circuit alerts are limited to 1 strike (versus 3) before
changing to alarm shut down state.
• The status of ALM.N is iNlored so all alerts and alarms
are broadcast on CCN.
• The words "SERVICE TEST" are inserted into every
atann message.
Smqce test can only be turned ON/OFF at the unit display.
Once mined ON, other entries may be made with the display or
through CCN.
NOTE: Service Test mode may be password protected. Refer
to Scrolling Marquee section on page 3 for more information.
To tum Service Test on, change the value of TEST to ON.
To turn service test off; change the value of TEST to OFF.
The independent (INDP) submenu is used to change output
stares for the economizer, power exhaust stages, and the alarln
relay. These independent outputs can operate simultaneously
with other Service Test modes. All outputs return to norlnal
operation when Smqce Test is mined off When the economiz-
er is using the factory default Digital Control Type (_bnfigura-
Iion--gECON--gE.(TL is 1 or 2) then the Economizer Calibra-
tion feature may be used to automatically check and reset the
economizer actuator range of motion.
The fans (FANg) submenu is used to change output status
for the indoor thn and outdoor tan stages.
The cooling (COOL) submenu is used to change output sta-
res for the individual compressors. Compressor starts are stag-
gered by 15 seconds. The thns (FA_Ig) and heating (HEAl)
service test outputs are reset to OFF for the cooling service test.
Indoor fans and outdoor tans are controlled nonnalty to main-
tain proper unit operation. All normal cooling alarms and alerts
are functional.
When charging unit, all outdoor thns may be tbrced on in
cooling service test modes by setting the Outdoor Fan Override
(OEOIO to on.
NOTE: Circuit A is always operated with Circuit B in
Humidi-MiZer TM system equipped units.
For units with the factory Humidi-MiZer option, the
Humidi-MiZer (HZMR) submenu is used to change the output
stares to operate the circuits in different Humidi-MiZer modes
or to separately test the Humidi-MiZer valve operations. The
tans (FANS), cooling (COOL), and heating (HEAT) semce
test outputs are reset to OFF for the Humdi-MiZer service test.
Indoor and outdoor thns are controlled normally to maintain
proper unit operation. All normal cooling alarms and alerts are
functional.
The heating (HEAl) submenu is used to change output sta-
res for the individual heat stages, gas or electric. The thns
(FANS) and cooling (COOL) smqce test outputs are reset to
OFF for the heating service test. Indoor and outdoor fmls are
controlled norlnalty to maintain proper unit operation. All nor-
mal heating alarlns and alerts are functional.
NOTE: Field terlninal strip terlninal R must be connected to
W1 for the heat to operate in service test. Alert number T410
will occur as a relninder if not done. If the normal unit control
mode is therlnostat mode, then relnove the R-W1 jumper after
completing service test.
