There are four connections on the UC800 that support 
the communication interfaces listed. See Figure 17 for 
the locations of each of these ports.

BACnet® MS/TP
MODBUS™ Slave
LonTalk™ using LCI-C (from the IPC3 bus)
Comm 4 using TCI (from the IPC3 bus)

There are three rotary switches on the front of the UC800 
controller. Use these switches to de

fi

ne a three-digit ad-

dress when the UC800 is installed in a BACnet or MOD-
BUS system (e.g., 107, 127, etc.).

Note:

Valid addresses are 001 to 127 for BACnet and 001 
to 247 for MODBUS.

There are 10 LEDs on the front of the UC800. 

Figure 22

 

shows the locations of each LED and 

Table 26

 describes 

their behavior in speci

fi

c instances.

Controls

LED

UC800 Status

Marquee LED 

Powered. If the Marquee LED is green solid, 

the UC800 is powered and no problems exist.
Low power or malfunction. If the Marquee 

LED is red solid, the UC800 is powered, but 

there are problems present.    
Alarm. The Marquee LED blinks Red when an 

alarm exists.

LINK, MBUS, IMC

The TX LED blinks green at the data transfer 

rate when the UC800 transfers data to other 

devices on the link.
The Rx LED blinks yellow at the data trans-

fer rate when the UC800 receives data from 

other devices on the link.

Ethernet Link

The LINK LED is solid green if the Ethernet 

link is connected and communicating.
The ACT LED blinks yellow at the data trans-

Service

The Service LED is solid green when pressed. 

use.

Important

:

   

Maintain at least 6 inches between low- volt-
age (<30V) and high voltage circuits. Fail-
ure to do so could result in electrical noise 
that could distort the signals carried by the 
low-voltage wiring, including IPC.

Information is tailored to operators, service technicians, 
and owners. When operating a chiller, there is speci

fi

c 

information you need on a day-to-day basis—setpoints, 
limits, diagnostic information, and reports. Day-to-day 
operational information is presented at the display. Log-
ically organized groups of information — chiller modes 
of operation, active diagnostics, settings and reports put 
information conveniently at your

ngertips.
