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.

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).
