*This default is model number dependent. VFD2 Deceleration Time (DECL) — This configuration sets the deceleration time from maximum output frequency to zero. Power to the VFD must be cycled in order for a change to this configuration to take effect. VFD2 Switching Frequency (SW.FQ) — This configuration sets the switching frequency for the drive. Power to the VFD must be cycled in order for a change to this configuration to take effect. VFD2 Type (TYPE) — This configuration sets the type of VFD communication. This configuration should not be changed without first consulting a Carrier service engineering representative. Remote Control Switch Input — The remote switch input is located on the RXB board and connected to TB201 terminals 3 and 4. The switch can be used for several remote control functions. See Table 68. Table 68 — Remote Switch Configuration ITEM EXPANSION RANGE UNITS CCN POINT REMT Remote Input State ON/OFF RMTIN RM.CF Remote Switch Config 0 - 3 RMTINCFG RMI.L RemSw Off-Unoc-Strt-NoOv Open/Close RMTINLOG Remote Input State (InputsGEN.IREMT) — This is the actual real time state of the remote input. Remote Switch Config (ConfigurationUNIT RM.CF) — This is the configuration that allows the user to assign different types of functionality to the remote discrete input. • 0 — NO REMOTE SW — The remote switch will not be used. • 1 — OCC-UNOCC SW — The remote switch input will control the occupancy state. When the remote switch input is ON, the unit will forced into the occupied mode. When the remote switch is OFF, the unit will be forced into the unoccupied mode. • 2 — STRT/STOP — The remote switch input will start and stop the unit. When the unit is commanded to stop, any timeguards in place on compressors will be honored first. When the remote switch is ON, the unit will be commanded to stop. When the remote switch is OFF the unit will be enabled to operate. • 3 — OVERRIDE SW — The remote switch can be used to override any internal or external time schedule being used by the control and force the unit into an occupied mode when the remote input state is ON. When the remote switch is ON, the unit will be forced into an occupied state. When the remote switch is OFF, the unit will use its internal or external time schedules. Remote Switch Logic Configuration (Configuration SW.LGRMI.L) — The control allows for the configuration of a normally open/closed status of the remote input switch via RMI.L. If this variable is configured OPEN, then when the Table 67 — Exhaust Fan VFD Configuration ITEM EXPANSION RANGE UNITS CCN POINT DEFAULTS E.VFD EXHAUST FAN VFD CONFIG N.VLT VFD2 Nominal Motor Volts 0 to 999 Volts VFD2NVLT 460* N.AMP VFD2 Nominal Motor Amps 0 to 999 Amps VFD2NAMP 28.7* N.FRQ VFD2 Nominal Motor Freq 10 to 500 Hz VFD2NFRQ 60 N.RPM VFD2 Nominal Motor RPM 50 to 30000 RPM VFD2NRPM 1750 N.PWR VFD2 Nominal Motor HPwr 0 to 500 H.P.

Correspondingly, if RMI.L is set to CLOSED, the remote input switch will perceive a closed switch as meaning OFF. See Table 69. Hot Gas Bypass — The ComfortLink control system supports the use of an optional minimum load hot gas bypass valve (MLV) that is directly controlled by the ComfortLink control system. This provides an additional stage of capacity as well as low load coil freeze protection. Hot gas bypass is an active part of the P-Series ComfortLink capacity staging and minimum evaporator load protection functions. It is controlled though the Minimum Load Valve function. The hot gas bypass option consists of a solenoid valve with a fixed orifice sized to provide a nominal 3-ton evaporator load bypass. A hot gas refrigerant line routes the bypassed hot gas from the discharge line of circuit A to the suction line of circuit A. An additional thermistor in the suction line allows the unit control to monitor suction superheat. When the unit control calls for hot gas bypass, the hot gas bypasses the evaporator and adds refrigeration load to the compressor circuit to reduce the cooling effect from Circuit A. The hot gas bypass system is a factory-installed option installed on Circuit A only. This function is enabled at ConfigurationCOOLMLV. When this function is enabled, an additional stage of cooling capacity is provided by the unit control staging sequences (see Appendix C). Space Temperature Offset — Space Temperature Offset corresponds to a slider on a T56 sensor that allows the occupant to adjust the space temperature by a configured range during an occupied period. This sensor is only applicable to units that are configured as Multi-Stage SPT control (ConfigurationUNITC.TYP = 4). ITEM EXPANSION RANGE UNITS CCN POINT SP.O.S Space Temp Enable/ SPTOSENS Offset Sensor Disable SP.O.R Space Temp Offset Range 1 - 10 SPTO_RNG SPTO Space Temperature Offset +- SP.O.R ^F SPTO Space Temperature Offset Sensor (ConfigurationUNIT SENSSP.O.S) — This configuration disables the reading of the offset slider. Space Temperature Offset Range (Configuration UNITSENSSP.O.R) — This configuration establishes the range, in degrees F, that the T56 slider can affect SPTO when adjusting the slider from the far left (-SP.O.R) to the far right (+SP.O.R). The default is 5° F. Space Temperature Offset Value (TemperaturesAIR.T SPTO) — The Space Temperature Offset Value is the reading of the slider potentiometer in the T56 that is resolved to delta degrees based on SP.O.R.
REMOTE SWITCH LOGIC CONFIGURATION (RMI.L) OPEN CLOSED SWITCH STATUS TIME CLOCK CONFIGURATION This section describes each Time Clock menu item. Not every point will need to be configured for every unit. Refer to the Controls Quick Start section for more information on what set points need to be configured for different applications. The Time Clock menu items are discussed in the same order that they are displayed in the Time Clock table. The Time Clock table is shown in Table 70. Hour and Minute (HH.MM) — The hour and minute of the time clock are displayed in 24-hour, military time. Time can be adjusted manually by the user. When connected to the CCN, the unit can be configured to transmit time over the network or receive time from a network device. All devices on the CCN should use the same time. Only one device on the CCN should broadcast time or problems will occur. Month of Year (MNTH) — This variable is the current month of the calendar year.

If this variable is set to NO, then the period’s occupied time schedule will not be used on Friday. This variable can be set for Periods 1 through 8. SATURDAY IN PERIOD (PER.XDAYSSAT) — This variable is used to include or remove Saturday from the schedule. Each period is assigned an occupied on and off time. If this variable is set to YES, then Saturday will be included in that period’s occupied time schedule. If this variable is set to NO, then the period’s occupied time schedule will not be used on Saturday. This variable can be set for Periods 1 through 8. SUNDAY IN PERIOD (PER.XDAYSSUN) — This variable is used to include or remove Sunday from the schedule. Each period is assigned an occupied on and off time.

HOLIDAY IN PERIOD (PER.XDAYSHOL) — This variable is used to include or remove a Holiday from the schedule. Each period is assigned an occupied on and off time. If this variable is set to YES, then holidays will be included in that period’s occupied time schedule. If this variable is set to NO, then the period’s occupied time schedule will not be used on holidays. This variable can be set for Periods 1 through 8. OCCUPIED FROM (PER.XOCC) — This variable is used to configure the start time of the Occupied period. All days in the same period set to YES will enter into Occupied mode at this time. OCCUPIED TO (PER.XUNC) — This variable is used to configure the end time of the Occupied period. All days in the same period set to YES will exit Occupied mode at this time. Local Holiday Schedules (HOL.L) — This submenu is used to program the local holiday schedules. Up to 30 holidays can be configured. When a holiday occurs, the unit will follow the occupied schedules that have the HOLIDAY IN PERIOD point set to YES. Holiday Start Month (HD.01 to HD.30MON) — This is the start month for the holiday. The numbers 1 to 12 correspond to the months of the year (e.g., January = 1). Holiday Start Day (HD.01 to HD.30DAY) — This is the start day of the month for the holiday. The day can be set from 1 to 31. Holdiay Duration (HD.01 to HD.30LEN) — This is the length in days of the holiday. The holiday can last up to 99 days. Daylight Savings Time (DAY.S) — The daylight savings time function is used in applications where daylight savings time occurs. The function will automatically correct the clock on the days configured for daylight savings time.
