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

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 oc-
cupied mode. The length of the time guard is 0 to 189 sec-
onds (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.
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 de-
termine the time guard length based on the TEMP system
thermostat device address.
To configure the Time Guard Override option, set cat-
egory 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 Heat-
ing 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 sys-
tem 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 sys-
tem 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 Cool-
ing Lockout Temperature Set Point, the TEMP system ther-
mostat will not select a system Cooling Mode. If the system
is currently 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 and cooling lock-
Heating Lockout Temperature Set Point —
Heating Lockout Temperature Set Point establishes the sys-
tem outside-air trip temperature for the Temperature Lock-
outs 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 decrease the set point. The default is 60 F.
Cooling Lockout Temperature Set Point —
Cooling Lockout Temperature Set Point establishes the sys-
tem outside air trip temperature for the Temperature Lock-
outs 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 decrease 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 moni-
tor thermostat is configured to receive a global schedule.
To program the Pre-Occupancy Purge option, configure
category 4, option 17. Use the left set point buttons to toggle
the option ON or OFF. The default is OFF.
The TEMP system thermostat has zone metering capabili-
ties. The available functions allow the TEMP system ther-
mostat to meter zone usage in 3 ways:
• usage of the heating/cooling equipment to maintain zone
temperature conditions (amount of time the zone demand
matches the System Mode).
• usage of the zone in addition to the normal occupied sched-
ule (amount of time the zone is in Unoccupied Override).
• amount of time zone demand matches system mode dur-
ing the unoccupied override.
HVAC Usage Meter —
stat has a HVAC usage meter that can accumulate up to
32,767 minutes (about 22 days) of HVAC usage. Through
communication, the amount of time accumulated in the meter
can be accessed, recorded, and reset to zero. Once the maxi-
mum amount of time has been accumulated, the TEMP sys-
tem thermostat stops metering and a Meter Full Error occurs.
To configure the HVAC Usage Meter option, set category
7, option 6. Use the left set point buttons to configure the
option ON or OFF. The default is OFF.
To disable the HVAC Usage Meter, set the option to OFF.
No metering occurs.
Override Usage Meter —
Meter option is set to ON, the meter will record the minutes
the zone is in unoccupied override mode. When the Over-
ride Usage Meter option is set to OFF, zone metering for this
mode will not occur. The override usage meter can accu-
mulate up to 32,767 minutes (about 22 days) of override
usage.
