Installation Manual
2.2 FAC Controller
An FAC controller is used to control the unit. The controller can connect
to the FC bus via the 4 pin FC connection.

FAC Controller
2.2.1 MAC Address
The physical MAC address of the FAC adjustable between 4-127
and is set via the DIP switch on the front of the unit. When multiple
controllers are connected on the same FC bus, each controller ‘s MAC
address must be unique.
2.2.2 BACnet Instance Number
The BACnet instance number of the FAC is factory-set to a random
unique value from 0-4,194,304. This ensures that every controller will
have a unique BACnet instance number on any possible network.
2.2.3 End Of Line (EOL) Resistor
When an FAC controller is used as a terminator at the end of a FC
bus line, the EOL resistor dip switch can be switched on for best
performance.
2.2.4 Fault Light Status
•Blink 5Hz - Not all possible room modules are connected. This
is normal.
•Blink 2Hz - Startup in progress
•Off Steady - No Faults
•On Steady - No Software
2.2.5 Current Loop DIP Switches
These should all be set to disabled. Enabling these switches will cause
incorrect sensor values.
2.3 BACnet IP To MS/TP Router (ESCO-IPN)
The BACnet IP to MS/TP Router exchanges information between
networks and allows the controller to communicate on an IP network.
One router is required for each MS/TP network.

ESCO-IPN
The BACnet router has a USB 2.0, Type B receptacle which is only used
to obtain power from a computer or USB adapter. A mains adapter
and cable is supplied. The router connects to the FC bus via screwed
terminals.
Address Type Default Address
IP Address 192.168.92.68
Subnet Mask 255.255.255.0 (/24)
A reset switch is available inside a small hole located on the side of the
case. If you press the reset switch with a paper clip (or similar device)
for at least 1 second, the switch resets to the default values of the IP
address, gateway address, and netmask. After you use the reset switch,
you need to reboot the router. The BACnet/IP to MS/TP Router contains
a Web server. You can access the Web server from any Internet-
compatible computer on the local network. To configure the router, you
need a computer with an Ethernet connection, router, and standard
Web browser.
2.4 Interconnection
The FC bus connects via the following MSTP cabling:
ESCO-MSTPC30M - Ecosmart Connect MSTP cable reel 30m
ESCO-MSTPC150M - Ecosmart Connect MSTP cable reel 150m
Suggested Wiring Colouring:
White +
Green -
Black COM
Red Unused
On the SA Bus, the + and - wire are one twisted pair, and the COM and
SA PWR are the second twisted pair of wires. These cannot be used with
RJ12 connections and must be stripped and connected using screwed
terminals. The shield must be earthed at the control panel end only and
be made continuous along the bus length. Room Modules must not be
fitted more than 150metres (cable length) from the controller.
2.5 Touch Screen (ESCO-LCD) Field Advanced Display (FAD)
The ESCO-LCD is a user friendly operator interface featuring BACnet®
communication and a colourful, graphic display with touch-screen
interface. It is powered by 12-24VAC / VDC and connected via the FC
bus.
