Temperature Lockouts; Heating Lockout Temperature Set Point; Cooling Lockout Temperature Set Point; Pre-Occupancy Purge - Carrier 33CS Installation, Service, And Troubleshooting Instructions

To configure the Second Stage Cooling Temperature Limit
option, set category 4, option 6. Use the left set point buttons to
raise or lower the set point until the desired temperature is
shown. The range of acceptable values is 45 to 50 F, in one de-
gree increments. The default is 50 F.
First Stage Heating Temperature Limit — If the duct
entering-air temperature rises above the First Stage Heating
Temperature Limit and the LAT Monitoring function is ON,
the TEMP system thermostat will deenergize first stage
heating.
To configure the First Stage Heating Temperature Limit op-
tion, set category 4, option 7. Use the left set point buttons to
raise or lower the set point until the desired temperature is
shown. The range of acceptable values is 110 to 180 F, in one
degree increments. The default is 110 F.
Second Stage Heating Temperature Limit — If the duct
entering-air temperature rises above the Second Stage Heating
Temperature Limit and the LAT Monitoring function is ON,
the TEMP system thermostat will deenergize second stage
heating.
To configure the Second Stage Heating Temperature Limit
option, set category 4, option 8. Use the left set point buttons to
raise or lower the set point until the desired temperature is
shown. The range of acceptable values is 105 to 160 F, in one
degree increments. The default is 105 F.
High/Low Temperature Limit Display — When a Heating or
Cooling Temperature Limit is exceeded the TEMP system
thermostat flashes the appropriate system annunciators.
COOL flashes when a Low Temperature Limit is exceeded.
HEAT flashes when a High Temperature Limit is exceeded. An
SE11 alarm will be issued.
HEATING AND COOLING TIME GUARD — When the
Time Guard Between Modes option is ON, the TEMP system
thermostat cannot change system modes until the heating/
cooling time guard period has expired. The heating and cool-
ing time guard is 5 minutes.
When the Time Guard Between Modes option is OFF, the
TEMP system thermostat cannot change system modes until a
30-second time delay has expired.
To configure the Time Guard Between Modes option, set
category 4, option 2. Use the left set point buttons to toggle the
option ON and OFF. The default is ON.
UNOCCUPIED TIME GUARD — The Unoccupied Time
Guard determines how long the TEMP system thermostat will
wait before starting the heating/cooling equipment when the
TEMP system thermostat goes from unoccupied to occupied
mode. The length of the time guard is 0 to 189 seconds (deter-
mined by the first 6 bits of the address of the heating/ cooling
equipment). This keeps the equipment from starting simulta-
neously which keeps peak energy usage down.
TIME GUARD OVERRIDE — When the Time Guard Over-
ride option is set to ON, the TEMP system thermostat heating/
cooling time guard and Unoccupied Time Guard are reset to
30 seconds.
NOTE: When the Time Guard Override option is used, the
TEMP system thermostat will automatically reset the Time
Guard Override to OFF.
When the Time Guard Override option is set to OFF, the
heating/cooling time guard and Unoccupied Time Guard deter-
mine the time guard length based on the TEMP system thermo-
stat device address.
To configure the Time Guard Override option, set category
4, option 3. Use the left set point buttons to toggle the option
ON and OFF. The Time Guard Override option will return to
OFF when the override is complete. The default is OFF.
POWER-UP TIME GUARD — The power-up time guard
determines how long the TEMP system thermostat will wait
before starting the heating/cooling equipment when the TEMP
system thermostat is powered up. The length of the time guard
is 5 minutes plus 0 to 189 seconds (determined by the first 6
bits of the address of the heating/cooling equipment). This
keeps the equipment from starting simultaneously which keeps
peak energy usage down.
Temperature Lockouts —
out temperatures can be configured to lock out the system
mode based on the outside-air temperature. When the Heating
Temperature Lockouts option is set to ON, and the outside-air
temperature exceeds the Heating Lockout Temperature Set
Point, the TEMP system thermostat will not select a system
Heating Mode. If the system is currently in the system heating
mode, the TEMP system thermostat will complete the current
system mode.
NOTE: In order to use lockout temperatures the TEMP system
thermostat must have an outdoor-air sensor wired to the relay
pack, or must be receiving outdoor-air temperature over the
network.
When the Cooling Temperature Lockouts option is set to
ON, and the outside-air temperature drops below the Cooling
Lockout Temperature Set Point, the TEMP system thermostat
will not select a system Cooling Mode. If the system is current-
ly in the system cooling mode, the TEMP system thermostat
will complete the current system mode.
When either the Cooling or Heating Temperature Lockout
options are set to OFF, the System Heating and Cooling Mode
Lockout functions are disabled.
To configure the Cooling Temperature Lockout option, set
category 4, option 11. Use the left set point buttons to toggle
the option ON and OFF. The default is OFF.
To configure the Heating Temperature Lockout option, set
category 4, option 13. Use the left set point buttons to toggle
the option ON and OFF. The default is OFF.
Heating Lockout Temperature Set Point —
Heating Lockout Temperature Set Point establishes the system
outside-air trip temperature for the Temperature Lockouts and
the Supplemental Heat Lockout.
To disable the TEMP system thermostat heating lockout
functions, set the Heating Lockout option to OFF.
To configure the Heating Lockout Temperature Set Point,
set category 4, option 14. The range of values is 10 to 80 F in
5° F increments. Use the left set point buttons to increase or de-
crease the set point. The default is 60 F.
Cooling Lockout Temperature Set Point —
Cooling Lockout Temperature Set Point establishes the system
outside air trip temperature for the Temperature Lockouts
function.
To disable the TEMP system thermostat cooling lockout
functions, set the Cooling Lockout option to OFF.
To configure the Cooling Lockout Temperature Set Point,
set category 4, option 12. The range of values is 10 to 80 F in
5° F increments. Use the left set point buttons to increase or de-
crease the set point. The default is 40 F.
Pre-Occupancy Purge —
purge option is set to ON, the TEMP system thermostat will
open the economizer and start the indoor-fan motor to send
fresh air into the zone 60 minutes before the occupied mode is
programmed to start. If the Auxiliary Relay is configured for
economizer control, the auxiliary relay will be energized.
When the Pre-Occupancy Purge option is set to OFF, the
purge will not occur.
NOTE: The Pre-Occupancy Purge will not work if the monitor
thermostat is configured to receive a global schedule.
To program the Pre-Occupancy Purge option, configure cat-
egory 4, option 17. Use the left set point buttons to toggle the
option ON or OFF. The default is OFF.
