Tracer™ UC400 Controller Operations
Modify Default Units: Use these drop-down lists to change the default units of measure
displayed for various device inputs or capabilities, such as Temperature, Gaseous Pressure,
Fluid Pressure, Cooling Capacity, and so on.
To set the controller units of measure
1. Click the Units expanding box.
2. Select your preferred Number Format from the Number Format drop-down list.
3. Select your preferred units of measure by clicking either the I-P (Inches and Pounds) or SI
(Standard International Units) option button in the Default Units group box.
4. Check the Modify Default Units check box if you want to change the default units of measure
displayed for various device inputs or capabilities, such as Temperature, Gaseous Pressure,
Fluid Pressure, Cooling Capacity, and so on.

the Modify Default Units group box.
6. Click Save.
Communication
Type: Displays the protocol that controllers use to communicate with other controllers on the
link. (The controller uses a different protocol to communicate with Tracer TU.)
Baud Rate: If the protocol is BACnet or Modbus, you can use this drop-down list to specify the
baud rate of the link, which depends on the network device to which the controller is being
linked.
Device ID
• Current Device ID: Displays the Device ID of the controller. The default Device ID is set
to the UC800 MAC address set on the rotary dials. The Device ID can also be soft set.
• Soft Set Device ID: If the BACnet protocol is being used, you can enter a soft set Device
ID. This is useful for integration with third-party equipment. (Select the check box to
activate the entry box.)
• Remove Soft Set ID: Use this button to clear the current value out of the Soft Set Device
ID box. You can then enter a new value. (You do not need to click this button when you
enter the first Soft Set Device ID. Use it only to change the Soft Set Device ID.)
To Set Up the Soft Set Device ID
You can specify a soft set device ID using the Tracer TU service tool tab Controller Settings screen
on the Controller Settings Utility tab, if the BACnet protocol is being used at your job location. A
soft set device ID is useful when you are integrating Trane equipment into a non-Trane
environment.
1. Select the Soft Set Device ID check box.
2. If no soft set ID is present, or if you want to change the existing soft set ID:
a. Select the Soft Set Device ID check box.
b. Enter a new ID.
c. Click Save.
d. Cycle the power to the controller to make the change effective.
3. If a soft-set ID is present, and you want to return it to a hard set device ID.
a. Click Remove Soft Set ID.
b. Click Save.
c. Cycle the power to the controller to make the change effective.
