BMS INTERFACE
The
E²
series controller may incorporate a 10 Mbps
communication interface port that can be fi eld connected
through a serial interface to a Building Management
System via Modbus, BACnet, SNMP, or HTTP as confi gured
by the factory. A controller interfaced to a network must
be confi gured 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 confi gure
operating parameters for the CyberRow® unit.
OPTIONAL ACCESSORIES
MECHANICAL FLOW SWITCH (OPTIONAL)
A shipped loose fl ow switch shall activate a loss of fl ow
alarm in the event of chilled water fl ow interruption.
DIFFERENTIAL TEMPERATURE
FLOW (OPTIONAL)
A factory mounted and wired temperature sensor for inlet
and outlet water temperatures shall permit a loss of fl ow
alarm in the event the temperature difference is within 1°
F (adjustable) during chilled water valve operation.

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 identifi ed 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 confi gured 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 confi gured 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.
