Open aisle configuration organizes racks in a single row
or in hot and cold aisle rows, but without containment.
The Stulz CyberRow® draws hot air from the external
environment or hot aisle, removes the heat, and supplies
cooled air to the front of IT equipment in the cold aisle.
Hot aisle containment captures the hot exhaust air from
IT equipment and prevents from mixing with cool air. The
front of IT equipment is accessed in the external cold
aisle. The Stulz CyberRow® draws the contained hot air
from the hot aisle, removes the heat, and supplies cooled
air into the external cold aisle.
Cold aisle containment captures cooled air from the
Stulz CyberRow® and prevents it from mixing with hot
air. The front of IT equipment is accessed in the contained
cold aisle. The Stulz CyberRow® draws hot air from the
external environment, removes the heat, and supplies
cooled air back into the contained cold aisle.

E² SERIES CONTROLLER DESCRIPTION
GENERAL
The 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 CyberRow® unit. 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 CONFIGURABLE
The 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 PROTECTION
Access 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

BMS INTERFACE
The E² series controller may 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.
ALARMS
Alarm 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.
SMALL BEZEL DISPLAY PANEL
The small bezel user interface display panel features an
easy to read, backlit liquid-crystal alphanumeric 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
6-key menu-driven loop structure 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 CyberRow® unit.
OPTIONAL ACCESSORIES
MECHANICAL FLOW SWITCH (OPTIONAL)
A shipped loose flow switch shall activate a loss of flow
alarm in the event of chilled water flow interruption.

personnel may perform modifications to the settings.
RESTORABLE PARAMETERS/FACTORY
DEFAULTS
Upon initial start-up the CyberRow® 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 FEATURE
The 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 CyberRow® unit to operate at night
with relaxed temperature/humidity setpoints and offsets.
A/C GROUPING pLAN OPERATION
Multiple CyberRow® 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 CyberRow® units 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 CyberRow® units 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 CyberRow® unit within the rotating group is
operationally exercised on a periodic timed basis.
