7InRow RD Technical Data Manual
Microprocessor Controller
Microprocessor Controller
The microprocessor controller is
standard on each unit. The controller
provides precision control for the
demanding requirements of the fol-
lowing environments:
• Computer rooms
• Telecommunication facilities
• Clean rooms
• Power equipment
• Medical equipment rooms
• LAN/WAN environments
The easy-to-use display interface
allows the operator to select options
from the menu-driven interface to
control and monitor the connected air
conditioning system.
Open Architecture
The InRow RD protocol is open for
integration with all building manage-
ment systems. Communication
interface on the system can be Mod-
bus RS485 or Ethernet.
Control Type
The controller utilizes proportional/
integral/derivative (PID), a time-
proven precision environmental con-
trol method. This allows for custom
tuning of control variables to achieve
desired system response.
Functions
• Supply and return air conditions
• Operational mode control
• Event logging
•Alarms
• Redundant group control
• Fan speed adjustment
• Input/output module programming
Logging
The event log keeps a record of all
alarms and events. Each event log
contains a time/date stamp as well as
operating conditions at the time of
occurrence. The controller also dis-
plays run time, in hours, for major
components (air filters, fans, and
condensate pump, as well as humidi-
fier, heater, and compressor for the
air-cooled unit).
Display Interface
The backlit, four-line by twenty-
character display interface is pass-
word configurable.
