Alarm conditions activate an audible and visual indicator. An alarm shall be acknowledged through a button located on the user interface. The C-6000 alerts to the following alarm conditions (if applicable): (Note: Remote Sensor installation is available as an option.) SYSTEM SETUP & ADJUSTMENTS The C-6000 shall be completely factory pre-programmed, and therefore, most applications will require no field setup. However, the “default” set points and their ranges are easily adjusted from the C-6000 interface. UNIT STATUS DISPLAY • Current Dry Bulb Temp Set Point • Current Relative Humidity Set Point • Actual Time Current Unit Status: The C-6000 LCD Graphic Display shall indicate current unit functions: 3-6 • • • • • SENSOR LOCATION OPTIONS: The C-6000 LCD Graphic Display shall indicate current room status: The User Interface shall feature an easy to read, liquid-crystal, graphical display.

High Temperature Low Temperature High Humidity Low Humidity High Head Press. Low Suction Press. Comm. Failure       Dirty Filter Loss of Air Flow Firestat Smoke Detection Leak Detection Sensor Failure Summary Alarm Contact: A summary alarm dry-contact (n/o or n/c) connection shall be available for remote annunciation of an alarm condition. An additional user-defined custom alarm drycontact shall also be available on most system configurations. Alarm History: The C-6000 controller provides users with a recorded history of the previous 80 alarms, including the time and date of the alarm. CONTROL INPUTS/OUTPUTS The C-6000 is capable of both digital (on/off) and analog input and output device control.

Microprocessor Controls - C-6000 An expansion board shall increase the capability by providing and additional 8 digital inputs and 8 digital outputs. Power Loss Restart In the event of a loss of power to the system, the C-6000 can be configured for Automatic or Manual Restart. The C-6000’s non-volatile memory enables the system to restart when power is restored, without the loss of the “last” stored set points and other system configuration settings. Sequential Load Activation To minimize the total in rush current loads during system startup/restart, the C-6000 controller shall be configured for time-delay sequence startup. The user can designate specific unit restart time-delays, as well as, each unit’s respective electric heater and/or humidifier. Unit restart delay can be adjusted from 0 to 10 minutes. Electric heater and/or humidifier restart delay can be adjusted from 0 to 60 seconds. Start Delay: After a power loss, the C-6000’s Start Delay feature allows the Precision A/C to operate with a delayed start period (adjustable up to 42 minutes). SECURITY Keypad Lockout The C-6000 includes a 2-level password protection feature that prevents unauthorized users from making changes to system setpoints and settings available directly from the multi-function interface. DIAGNOSTICS AND SERVICE MODE The C-6000 shall incorporate a unique self-diagnostics algorithm that continually tests systems functions and hardware operation. In the event of such a failure, the user will be alerted to the condition via a visual and audible alarm. Control Board The Control Board shall initiate a self-test of the control system. number of “standby” units can be designated as any number. Automatic timed change over is designated between 1 and 255 hours. Automatic change-on-failure can be user customized by selecting which normally displayed alarms will result in a switchover to the “standby” unit. As well, standby units can be sequenced to maintain temperature and or humidity as needed. It is necessary that the remote sensor option be utilized for this function. The Multi-Unit Sequencing function shall exist inherently within the standard C-6000 controller. Interconnect wiring between the RS-485 data bus ports as well as field configuration from the C-6000 user interface shall be all that is required to incorporate this feature. When BMS communication is required (MIB Gateway), the RS-485 serial port shall be utilized for the MIB interface. The Multi-Unit Sequencing function shall then be accomplished in the same manner as described above but via the MIB Gateway.

The system shall provide premium setpoint accuracy while controlling the room conditions rate of change, minimizing the equipment energy consumption and maximizing the system’s operating life and reliability. Recovery Delay After a power loss, the C-6000’s Recovery Delay feature allows the Precision AC A/C to operate without initiating any high or low temperature or humidity alarms for a delayed period. This feature allows the A/C time (adjustable up to 42 minutes) to “pull-down” the conditioned space’s load without nuisance alarms during initial startup or power loss restart.

The secondary/backup mode of cooling shall be a dual compressor, DX refrigerant circuit. The C-6000 microprocessor's Alternate Water Source program algorithm shall analyze input data from factory provided and installed water flow switch, aquastat and return room air temperature, and relative humidity sensors. Based on this data, the C6000 microprocessor shall automatically control the sequencing of the primary AWS chilled water to and from the secondary/backup dual compressor DX modes of operation. If chilled water is available, the system shall operate like a chilled water unit, without the compressors operating.
