Two levels of microprocessor control systems are available providing precise control and monitoring of the critical space.
The Advanced Microprocessor is standard, and the Advanced Microprocessor with Graphics is optional. The main control functions are similar for both controls.
The user must enter a
•Temperature Setpoint
•Temperature Sensitivity
•Humidity Setpoint
•Humidity Sensitivity
•High Temperature Alarm
•Low Temperature Alarm
•High Humidity Alarm
•Low Humidity Alarm
*The microprocessor may be set within these ranges; however, the unit may not be able to control to extreme combinations of temperature and humidity.
•Input diagnostics: Reviews inputs to the con- trol system.
•Control board diagnostics: Initiates a
•Output diagnostics: Tests major components by turning them on and off from the control panel. Includes: main fan, compressor, liquid line solenoid valve, hot gas bypass valve, chilled water or chilled GLYCOOL valve,
•Alarm history log: The Advanced Microproces- sor displays the 10 most recent alarms. The Advanced Microprocessor with Graphics displays the most recent 60 alarms. Both provide a time and date stamp for each event
•Run time log: Displays run time and hours for major components (also allows reset of run hours) including compressors, GLYCOOL, fan, humidifier, and reheat.

•Compressor short cycle control: Prevents compressor
•System auto restart: The auto restart feature will automatically restart the system after a power failure. Time delay is programmable.
•Sequential Load Activation: On initial
•Hot Water /
•Temperature/Humidity Sensor Calibration: The sensors may be calibrated from the front mon- itor panel to insure that all units in the room are similarly calibrated, assuring greater precision.
•Normal display: Includes present room temper- ature and humidity, active functions (cooling, heating, dehumidifying), and any alarms.
•Operating status: Displays each control opera- tion in percent.
•Read analog inputs function: Displays the present values of up to four analog inputs.
•Humidifier problem
•High head pressure
•Change filter
•Loss of air flow
•High temperature
•Low temperature
•High humidity
•Low humidity
•Compressor overload (opt)
•Main fan overload (opt)
•Low suction pressure
•Short cycle
•Loss of power
•Custom alarm (choose up to 4)
•Water under floor
•Smoke detected
•Standby GC pump on
•Loss of water flow
