Advanced Microprocessor
Temperature & Humidity
Controller with Alarms
The A/C unit shall be provided with SATS’ CompTrol 5000® Micropro-cessor based Temperature and Humidity controller with Alarms. The controller shall incorporate a “user-friendly” operating environment, to allow easy system setup and opera-tion.
The CompTrol 5000® (C-5000) is a complete microprocessor based control system designed for operat-ing, controlling and monitoring the precision air conditioning unit. The C-5000 controller shall include a full-featured LCD graphical display for visual indication of the unit operating conditions.
USER INTERFACE:
The User Interface shall feature an easy to read, liquid-crystal, graphical display. The attractive unit mounted interface, allows the operator to
visually monitor and customize unit functions and settings. The controller is operated via a 4-key menu-driven windows type structure, in three different modes; Information, Opera-tion, and Service.
FIELD CONFIGURABLE:
The C-5000 controller is field pro-gram configurable and capable of matching the unique needs of any data center, telecommunication or other critical area.
SENSOR LOCATION:
As a standard, the C-5000 tempera-ture and humidity sensor shall be factory unit mounted in the return air stream of the Precision AC unit.
SYSTEM SETUP & ADJUSTMENTS:
The C-5000 shall be completely factory preprogrammed, and there-fore, most applications will require no field setup. However, the “default” set points and their ranges are easily
adjusted from C-5000 keypad/
display.
UNIT STATUS DISPLAY:
The C-5000 keypad displays current unit functions and room status:
Current Dry Bulb Temp
Current Relative Humidity
Actual Time
Current Unit Status:
System ON/OFF Cooling Heating Humidifying Dehumidifying Reheating Run Times
The historical run-time in hours of the following major components is available directly from the C-5000 keypad/display: (if applicable)
• Evaporator Blower Motor • Compressor
• Humidifier
• Chilled Water Valve
ALARM CONDITIONS:
Alarm conditions activate an audible and visual indicator. An alarm shall be acknowledged through a button located on the keypad display. The C-5000 alerts to the following alarm conditions (if applicable):
High Temperature Dirty Filter
Low Temperature Smoke Detection
High Humidity Firestat
Low Humidity Leak Detection
High Head Press GC Pump Failure
Low Suction Press Sensor Failure
Loss of Air Flow Comm. Failure
Summary Alarm Contact:
A summary alarm dry-contact (n/o) connection shall be available for remote annunciation of an alarm condition.
Alarm History:
The C-5000 controller provides users with a recorded history of the previ-ous 80 alarms, including the time and date of the alarm.
CONTROL INPUTS / OUTPUTS:
The C-5000 is capable of both digital (on/off) and analog input and output device control. Prior to shipment, each Precision AC unit’s C-5000 is factory program configured to match the unit’s system operational require-ments.
Temperature Anticipation:
The C-5000 shall incorporate a self-calibrating and self-adjusting control logic that adjusts the response of the SATS air conditioner to changes in temperature and humidity. The system shall provide premium
C-5000 Series Controls:

setpoint accuracy while controlling the room conditions rate of change, minimizing the equipment energy consumption and maximizing the system’s operating life and reliability.
POWER LOSS RESTART:
In the event of a loss of power to the system, the C-5000 can be config-ured for Automatic or Manual Re-start. The C-5000’s non-volatile memory enables the system to restart when power is restored, without the loss of the “last” stored setpoints and other system configu-ration settings.
Sequential Load Activation:
To minimize the total in rush current loads during system startup/restart, the C-5000 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 compressor, electric heater and/or humidifier. Unit restart delay can be adjusted from 0 to 10 minutes. Unit compressor, electric heater and/or humidifier restart delay can be adjusted from 0 to 60 seconds.
Recovery Delay:
After a power loss, the C-5000’s Recovery Delay feature allows the Precision 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 (15 to 60 minutes adj.) to “pull-down” the conditioned space’s load without nuisance alarms during initial startup or power loss restart.
COMPRESSOR OPERATIONS:
Short Cycle Protection:
Each compressor shall be protected from frequent compressor cycling through the C-5000’s minimum
compressor ON and minimum compressor OFF short cycle timers.
Cold Start Time Delay:
Each compressor of a DX Split System shall be provided with the C-5000’s Cold Start compressor time delay. The Cold Start timer delays, and therefore, overrides the system’s refrigerant low suction pressure switch during system startup. This allows the system time to build sufficient discharge pressure during cold weather startup.
SECURITY:
Multiple security levels prevent unauthorized adjustment of critical system parameters. The user may select a four-digit password for setpoint and configuration changes.
Password Protection:
The C-5000 includes a selectable password protection feature that prevents unauthorized users from making changes to system setpoints and settings available directly from the multi-function keypad/display.
DIAGNOSTICS & SERVICE MODE
The C-5000 incorporates a unique self-diagnostics algorithm that
continually tests system 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:
Initiates a self-test of the control system.
Input Diagnostics:
All system inputs and output devices are continuously monitored for proper operation.
TWO UNIT SEQUENCING:
Critical control applications shall be addressed with the C-5000 two-unit sequencing program logic. Under an A/C failure condition the controller will automatically initiate the unit operation of the designated standby/ backup unit, as well as, locally and remotely alert the alarm condition. The two-unit sequencing control logic shall automatically initiate the current standby unit upon a system failure alarm condition.
The control is programmed to automatically change from the current primary unit operation to secondary/standby unit operation via two methods:
1) Automatic Timed (every 7 days) 2) Automatic Changeover on Unit Failure
As well, the control shall also enable the standby/backup unit in the event that the primary unit is not able to handle the cooling requirement. As the maximum room temperature limits are reached with the primary unit, the standby/backup unit shall become enabled to assist in the cooling requirement until room conditions are back within a satisfac-tory range.
