UC800 Specifications
Power Supply
eq uiip an mo
The UC800 (1A22) receives 24 Vac (210 mA) power from the 1A2 power supply located in the chiller control panel.
Wiring and Port Descriptions
The following figure illustrates the UC800 controller ports, LEDs, rotary switches, and wiring terminals. The numbered list following the figure corresponds to the numbered callouts in the illustration.

Communication Interfaces
There are four connections on the UC800 that support the communication interfaces listed. Refer to
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)
Rotary Switches
There are three rotary switches on the front of the
UC800 controller. Use these switches to define a threedigit address when the UC800 is installed in a BACnet® or MODBUS® system (e.g., 107, 127, etc.).

UC800 Status
Powered.
If the Marquee LED is green solid, the

Adjusting the Tracer AdaptiView
Display Arm
The Tracer® AdaptiView™ display arm may become too loose or too tight and may need adjustment. There are three joints on the display arm that allow the display to be positioned at a variety of heights and following figure).
Figure 36.
Joint locations on the display arm
To adjust the tension on the display arm:
• At each joint in the display arm, there is either a hex screw in the proper direction to increase or decrease tension.

• Joint 3 tension on a gas spring, which allows the Tracer®
AdaptiView™ display to tilt up and down.
• Joints 1 2 are covered by a plastic cap. Remove the plastic cap to access the hex bolt. Adjust using a
13 mm wrench as necessary.
• To adjust the swivel rotation tension of the Tracer®
AdaptiView™ display, adjust the hex bolt located in the support arm base plate, as described in the final step in
