Controls Interface
Unit Controller — General
The FWCD controller is a rugged microprocessor-
based controller designed for the hostile
environment of the HVAC/R industry. It is
designed to be the primary manager of the FWCD
product.
The controller provides flexibility with setpoints
and control options that can be selected prior to
commissioning a system or when the unit is live
and functioning. Unit display presents pressure,
temperature and alarm information with history in
a clear and simple language format, informing the
user of the chiller status. See wiring diagram in the
wiring section of this manual and attached to the
inside of the control panel door.
A password is required to access chiller setpoints.
Use password code 2112 to access many of these
features. A factory code may be required to allow
access to critical areas, and can only be entered by
a factory representative.
An RS-485 port is provided for communication
with other manufacturers’ systems.
Additionally, a built-in RS-485 to RS-232
converter allows communication over the RS-485
network via the RS-232 port.
Other features include the integration of BACnet
IP
®
and MODBUS
®
into the unit controller.
Optional communication cards are available for
communication via LONW
ORKS
®
, Johnson N2 and
BACnet MS/TP
®
. This should be ordered with the
chiller if required. An ethernet connection is also
provided on each unit. While field changes can be
made, please ensure that the unit is ordered set up
for required communications to ensure that factory
testing includes end user configuration.
A complete software support package is available
for your PC allowing for system configuration,
dynamic
on-line
display
screens,
remote
communication, graphing and more. Downloads
for the MCS-Connect software are available at
www.mcscontrols.com
at
no
charge.
All
information needed to run the unit is available
from the unit display; however, a laptop computer
is invaluable for ease of use of diagnosing or
changing the unit setpoints.
Note: Not all setpoints can be changed with MCS-
Connect; some require a configuration change.
A serial cable is included in each shipment for the
convenience of the field technician. If you do not
have a laptop with a serial port, you will require a
converter such as a Black Box item number
#IC199A-R3 serial-to-USB adaptor.
The FWCD standard configuration allows for the
unit to start at the lowest stage possible, and then
add compressors as needed to meet demand.
Important: All configuration changes need to be
done by factory representatives to ensure proper
operation of the unit within design parameters.

Software Installation and Setup
Downloading and Installing Unit Controller
(MCS-Connect) Software
Go to www.mcscontrols.com.
Go to the software page and select MCS-
CONNECT. Select SAVE. After downloading,
open and select RUN. Follow prompts and
software will be installed on your computer.
If your computer does not have a serial port, you
will need to purchase a USB to Serial adapter.
(Computer stores should have this.) Install the
software for the adapter. If your computer has a
serial port, you will not need an adapter.
Start the MCS-CONNECT software. Select
SETUP>COMMUNICATIONS and then change
LOCAL COM PORT to match your computer.
Select SAVE and then OK.
