CyberAiR Systems Offer Outstanding Advantages

Versatility• Down-Flow and Up-Flow Air Patterns• Ducted Systems• Raised Floor Mounting with Floor Stands

100% Front Service AccessFrom 60 to 730 kW, STULZ CyberAiR systems are designed for 100% Front Only Access. The compact foot-print requires minimal floor space.

Non-Proprietary PartsSTULZ CyberAiR systems incorporate non-proprietary components where possible. Most major HVAC, refrigeration and electrical distributors stock an exact model cross reference or an alternate to most factory provided components.

Microprocessor ControlPrecision temperature and/or humidity control with highly versatile and flexible E2 series controls. Designed primarily for STULZ precision air conditioners, E2 controllers offer a wide range of expanded control functions and alarms.

The E2 controller features a “menu-driven” operating environment to allow system setup and operation via an easy to read user interface display panel which is typically mounted on the front door of the STULZ CyberAiR system.

Electronically Commutated (EC) FanMaintenance free, highly reliable EC (Electronically Commutated) Fans offer considerable cost savings and long life. EC Fans do not use drive belts so belt abrasion dust is eliminated as is routine belt maintenance.Fan speed is continuously adjustable via a signal from the system controller without the use of VFD’s. EC fans offer clean, energy efficient, quiet and low vibration operation.

Complete Temperature & Humidity Control • Electrode Canister Steam Humidification

• Dehumidification Mode with - Staged Electric Reheat/Heat - Optional Hot Water Reheat/Heat

24/7 Year Round OperationOption offerings available with CyberAiR systems allow for year-round, 24 hrs-a-day A/C operation in any environment in the world.

Automatic Dual Power Transfer Switch (Optional) Two individual main power input disconnect switches shall be provided, one for each incoming power source. In the event the primary power fails or a phase loss/imbalance occurs, the automatic transfer switch immediately transfers power to the secondary power source. Once the primary power has been restored, the transfer switch automatically shifts the power load back to the primary power. The transfer time from one source to the other is user adjustable to allow staging or sequence restart of load.

In addition to the automatic transfer switch function, the local controller display shall indicate which power source has

failed. This indication is a visual depiction that allows the user to determine the status of the input source. This status shall be conveyed thru the BMS serial communications link.

A thru-the-door indicator light shall be included for a fast and local notification of available power sources.

AIR CONTROL

EC Fan Speed Control The system shall include a variable fan speed control package. The unit’s controller shall permit control of the fan speed from 100% rated air volumetric flow rate to a user define minimum fan speed setting. Minimum and maximum fan speed settings shall be user adjustable. User configured control sequences shall be available for fan speed energy savings control.

Fail Safe ModeIn the event of a fan failure, the controller shall automatically enable all remaining EC fans to increase to the maximum fan speed setting.

E² SERIES CONTROLLER DESCRIPTION

GeneralThe advanced microprocessor based E² Series controller shall be equipped with flexible software capable of meeting the specific needs of the application. The setpoints shall be default and their ranges shall be easily viewed and adjusted from the user interface display. The program and operating parameters shall be permanently stored on a non-volatile system in the event of power failure.

The controller shall be designed to manage temperature and relative humidity (RH) levels to a user defined setpoint via control output signals to the CW system. Control parameters have variable outputs from 0 to 100% of the full rated capacity.

The controller shall receive inputs for measurable control conditions (temperature, relative humidity, and dew point) via return air or room mounted sensors. The internal logic will then determine if the conditions require cooling, humidification or dehumidification. Control setpoints shall be established to maintain design conditions of the installation. The controller will respond accordingly to changes in these conditions and control the output/demand for the appropriate mode of operation until user defined conditions are achieved.

Field ConfigurableThe program for the E² Series controller shall be field configurable, allowing the operator the capability of selecting control setpoints specific to the application. Operator interface for the E² controller is provided via a door mounted user interface display panel. The display panel shall have a backlit LCD graphical display and function keys giving the user complete control and monitoring capability of the precision cooling system. The menu driven interface shall provide users the ability to scroll through and enter various menu screens.

Password ProtectionAccess to the Info Menu, Alarms Log, and the ability to monitor room conditions shall be allowed without the use of a password. Modifications to the control setpoints shall require the use of a password. The controller shall be programmed to recognize predetermined security levels before allowing access to display screens containing critical variables. Three secured menu levels (Control, Service and Factory) will support unique passwords that must be entered to access the menu screens so only authorized personnel may perform modifications to the settings.

Restorable Parameters/Factory DefaultsUpon initial start-up the CW system shall operate using the setpoints programmed by the factory. The customer may enter new operating parameters in the Control menu and the system will then operate accordingly. The new setpoints may be stored as, “Customer Default Setpoints”. The primary setpoints entered by the factory still remain stored in the controllers’ memory as, “Factory Setpoints”. The setpoints for the system may be re-adjusted in the Control menu at any time. If it becomes necessary, the customer may restore the setpoints back to the Customer Default setpoint values or to the original Factory (primary) setpoint values.

Timer FeatureThe timer shall allow the user to set up an operating schedule to automatically scale back or shut down the air conditioner during low demand or unoccupied periods. This is an energy saving feature offering the user the ability to create an operating schedule tailored to the needs of the building. An evening (night-setback) schedule may also be created, allowing the CW system to operate at night with relaxed temperature/humidity setpoints and offsets.

A/C Grouping pLAN OperationMultiple STULZ CyberAiR system controllers shall be able to be connected (grouped) to a pLAN local network, allowing

the communication of data and information from each controller to a central control terminal or Lead controller. The Lead controller display screens can be used to monitor and adjust group control variables for the individual system controllers. Each E² controller connected to the pLAN network shall be identified with its own unique address.

Multiple STULZ CyberAiR systems consisting of up to eight STULZ precision air conditioners equipped with like controllers may be controlled and monitored via the E² series controller. With multiple STULZ CyberAiR systems each unit can selectively be configured as “Active” to operate as a primary A/C, “Capacity Assist” for staged operation, or as “Standby” to come online in case of a failed air conditioning unit to ensure continuous availability. The controller may also be configured to rotate units with timed duty cycling to promote equal run-time and assure that each STULZ CyberAiR system within the rotating group is operationally exercised on a periodic timed basis.

BMS Interface (Optional)The E² series controller shall incorporate a 10 Mbps communication interface port that can be field connected through a serial interface to a Building Management System via Modbus, BACnet, SNMP, or HTTP as configured by the factory. A controller interfaced to a network must be configured for BMS communication.

AlarmsAlarm conditions shall activate a red LED indicator that backlights the alarm function key. As an option, an alarm condition may also be enunciated by an audible alarm signal. An alarm is acknowledged by pressing the alarm key. This calls up alarm display screens that provide a text message detailing the alarm conditions. After an alarm condition is corrected, the alarm can be cleared by pressing the alarm key.

Large Bezel Display Panel- Touch ScreenThe large bezel touch screen user interface display panel features a high resolution backlit liquid-crystal graphical display equipped with contrast adjustment and LED illuminated function keys. The screens that appear on the user interface display panel present data that originates from the controller I/O module. The controller is operated via a round membrane type keypad and offers an alarm log plus four different interface menu levels to the operator: Information, Control, Service, and Factory. These menus permit the user to easily view, control, and configure operating parameters for the STULZ CyberAiR system.
