Occupied Set Point Limiting; Unoccupied Mode Operation; Unoccupied Set Points; Occupancy Schedules - Carrier 33CS Installation, Service, And Troubleshooting Instructions

Occupied Set Point Limiting —
point limits establish the maximum allowable heating set point
and the minimum allowable cooling set point. The range of
allowable temperature limits is 50 to 99 F for heating and
cooling.
The Cooling Set Point Low Limit is set in category 1, op-
tion 1. The left set point buttons control the cooling set point
limit. Press the top set point button to raise the set point limit.
Press the bottom set point button to lower the set point limit.
The cooling set point limit is displayed in the top of the TEMP
system thermostat screen. The default value is 68 F.
The Heating Set Point High Limit is set in category 1,
option 2. The left set point buttons control the heating set
point limit. Press the top set point button to raise the set point
limit. Press the bottom set point button to lower the set point
limit. The heating set point limit is displayed in the TEMP
system thermostat screen. The default value is 75.
By limiting the occupied set points to a defined range, the
heating and cooling system will operate within desired pa-
rameters. The occupied system will minimize extended unit
cycles to heat or cool a zone.
TEMPERATURE DISPLAY — Temperature sensor infor-
mation is displayed by the TEMP system thermostat in in-
crements of 1/10° F. Temperature and units are displayed in
the top of the display. The temperature scale can be set to
either Fahrenheit or Celsius units.
To enable the Fahrenheit Temperature Display option, set
the category to 1 and the option to 6. Use the left set point
buttons to toggle the option ON or OFF. ON will display
temperature in Fahrenheit. OFF will display temperature in
Celsius.
NOTE: Absolute temperatures (temperatures not measured
by devices) are always in Fahrenheit, irrespective of the set-
ting of the Fahrenheit Temperature Display option.

UNOCCUPIED MODE OPERATION

Unoccupied mode is the time period when the TEMP sys-
tem thermostat maintains the unoccupied set point tempera-
tures. Unoccupied time periods follow the schedule of the
TEMP system thermostat zone. Unoccupied time periods al-
low for lower heating temperature set points and higher cool-
ing temperature set points to conserve energy and money
when the zone is unoccupied.
The TEMP system thermostat unoccupied time periods may
be controlled:
• locally by the TEMP system thermostat, which will follow
its own programmed unoccupied and occupied time
periods
• through communication from another device on the net-
work, which will send the TEMP system thermostat an un-
occupied schedule.
During local control the unoccupied/occupied programs
can be locked to prevent unauthorized or unintentional changes.
When the TEMP system thermostat is in a time period des-
ignated for unoccupied mode operation, zone occupants can
temporarily override unoccupied operation to the occupied
mode. During unoccupied override, the TEMP system ther-
mostat will maintain configured occupied conditions. At the
end of the override period, the TEMP system thermostat will
automatically return to unoccupied mode operation.
When the TEMP system thermostat is operating in unoc-
cupied mode, the unoccupied set points will be displayed on
the TEMP system thermostat screen.
Unoccupied Set Points —

in the zone controlled by the TEMP system thermostat
The occupied set
The unoccupied set points
during the unoccupied mode. The range of allowable tem-
peratures is 50 to 99 F for heating and 40 to 99 F for cooling.
To configure the unoccupied cooling set point, enter cat-
egory 1, option 3. The left set point buttons control the un-
occupied cooling set point. Press the top set point button to
raise the set point. Press the bottom set point button to lower
the set point. The unoccupied cooling set point is displayed
in the top left corner of the TEMP system thermostat screen.
The default value is 80 F.
To configure the unoccupied heating set point, enter cat-
egory 1, option 4. The left set point buttons control the un-
occupied cooling set point. Press the top set point button to
raise the set point. Press the bottom set point button to lower
the set point. The unoccupied heating set point is displayed
in the top left corner of the TEMP system thermostat screen.
The default value is 65.
Occupancy Schedules —
establishes the time periods when the TEMP system ther-
mostat operates in the occupied or unoccupied mode.
The unoccupied/occupied program has an individual 7-day
programming schedule with 8 time periods. Unoccupied/
occupied ON/OFF times are entered on the minute. The start
of an ON time is the beginning of the occupied mode. The
start of an OFF time is the beginning of the unoccupied mode.
NOTE: If an ON time and an OFF time are set for the same
hour, the TEMP system thermostat operates in unoccupied
mode for that entire day.
The Unoccupied/Occupied program of the TEMP system
thermostat can be configured locally using program mode.
The TEMP system thermostat will follow the holiday time
schedule on days that are configured as holidays in the Holi-
day Configuration tables. If a local occupancy schedule is
being used, then the local holiday configuration will be used.
Occupancy schedules received from the network already have
holiday information included.
PROGRAMMING SCHEDULES USING SOFTWARE —
The occupancy time schedule consists of 8 periods. From
the network access software each period may be configured.
Three configuration options are set from the software: Oc-
cupied From, Occupied To, and Days of the Week the sched-
ule is in effect. Eight different days are recognized: Monday
through Sunday, and Holiday.
OCCUPANCY SCHEDULE MODE — The unoccupied/
occupied program can be directly configured at the TEMP
system thermostat. Press both upper (or lower) set point but-
tons at the same time to enter into the program mode. The
occupancy schedule is in category 2, options 1 through 8.
Option 1 is occupied period 1. Option 2 is occupied period
2. The options continue to option 8 which is occupancy pe-
riod 8.
The procedure is different than programming other op-
tions. When category 2 is shown on the display screen, press
the select (lower right) button. The display will show option
1. This will show the start time for option 1 only. To modify
the start time for option 1, press select. Only the start time
is modified. To modify to the stop time for option 1 press the
upper left set point button. Instead of displaying option 2,
the stop time for option 1 will be shown. Press the select
button to modify the stop time. To modify the days of the
week that the occupancy period will be active, use the upper
left set point button to advance to the next option. Instead of
showing option 2, the screen will display the active days for
the occupied schedule. Each occupied period (options 2.1
through 2.8) will have three different screens associated with
it: start time, stop time, and active days.
