clearly defined prompts shall allow the operator to easily move about the program and monitor the following functions and alarm conditions.

•Status: Complete status monitoring shall be provided within the status menu of the microprocessor controller, and shall include the following information: current temperature, current humidity, temperature setpoint, humidity setpoint, cooling status, heating status, humidification status, and dehumidification status.

•Alarms: Quick access to any alarm condition shall be facilitated through the menu structure. Presence of a new alarm shall sound an audible alarm. A red alarm LED on the display panel shall remain illuminated until such time that all alarms have been cleared. Alarm annunciation shall include: loss of air, clogged filter, high head pressure, low suction pressure, high temperature, low temperature, high humidity, low humidity. The temperature and humidity alarm setpoints are user adjustable.

•Setpoint: The microprocessor controller shall provide independent setpoints for heating, cooling, humidification, and dehumidification. Automatic setpoint cross-over protection shall prevent the setting of the heat setpoint above the cool setpoint, and the humidify setpoint above the dehumidify setpoint. Setpoint adjustment shall be capable of being protected via security code.

•Configuration: Flexibility shall be offered through the use of the configuration menu. It shall closely match the operating requirements by changing the configuration settings. The site configuration shall be stored in the EEPROM and be protected from unauthorized tampering by the user selectable 4-digit security password in the security menu. Configuration options shall include: Fahrenheit or Celsius display, compressor minimum off-time, power-loss restart time-delay, primary- secondary transfer functions, alarm input polarity, alarm enable, temperature deadbands, humidity deadbands, and small room delay.

•Run time: The major components within the unit (motor, humidifier and compressor) shall have independent run-timers that monitor and store the accumulated run-hours on the components. The run timers shall be provided with operator-adjustable run-time alarms for proper component maintenance.

•Security: The microprocessor shall have multiple security levels to prevent unauthorized adjustment of important system parameters. A user-selectable 4-digit password shall allow setpoint and configuration changes.

Cabinet and frame. The cabinet and frame shall be constructed from welded structural steel. Access panels shall be flush with the frame and insulated with fiberglass 1" (25 mm) in thickness, 1.5lb/ft3 (0.7kg/m3) in density.

The panels are powder coated and lift off for access to the unit. A piping and electrical access plate shall be provided in the bottom of the unit. All units require front and left side access, 24" (610 mm) minimum.

Blower system. The unit shall be configured for draw-through air pattern, to provide uniform air-flow over the entire face of the coil. The blower shall be
