FINCH II-W / FINCH II-6W → FINCH III
Use this guide to understand what stays compatible, what changes with FINCH III, and what your team should confirm before beginning the display upgrade.
Applies to FINCH II-W and FINCH II-6W displays only — not the older FINCH II or FINCH 5332E.

Upgrade overview
What stays the same
FINCH III was designed to make the upgrade familiar for installers and operators while preserving compatible parts of the existing system.
Same installation footprint
FINCH III fits the existing FINCH II-W / FINCH II-6W mounting footprint, which simplifies replacement on an existing build.
Familiar operator interface
The display layout and core operating experience remain recognizable for drivers and service teams.
Same alarm behaviour
Existing alarm expectations remain familiar, reducing the need to retrain operators on basic alarm response.
Compatible field hardware
Existing compatible probes and TD100 transmitters can remain in service when they are in good condition and suited to the application.
FINCH III capabilities
What changes
The physical upgrade is familiar, but FINCH III introduces a simpler installation and configuration workflow along with expanded system capabilities.
The programming workflow has changed
FINCH III moves configuration away from the legacy programming tools and into Titan's current software workflow.
Used with earlier hardware for direct programming and configuration.
Use Titan Portal to support system access and Titan Install to connect to and configure FINCH III hardware.
SensorLink is not used to program FINCH III. Confirm that the person completing the upgrade has access to Titan Portal and Titan Install before arriving at the truck.
Plan the installation
What hardware will you need?
The required hardware depends on the number of compartments and whether the existing transmitters and probes are compatible.
| Single compartment | FINCH III display, one compatible TD100 transmitter, and one compatible probe. Existing compatible hardware may be retained if it is serviceable. |
|---|---|
| Two to six compartments | FINCH III display, Titan multi-compartment junction box, one compatible TD100 transmitter per compartment, and a compatible probe for each compartment. |
Pre-installation check
Before you begin
Confirm these items before removing the existing display or changing the truck wiring.
- Verify that the existing display is a FINCH II-W or FINCH II-6W.
- Identify every transmitter and probe currently installed and confirm compatibility with FINCH III.
- If the system uses a TD80 transmitter, plan the TD80 → TD100 upgrade separately.
- Confirm the total number of compartments and whether a Titan junction box is required.
- Make sure the installer has working access to Titan Portal and Titan Install.
- Document the current wiring and alarm connections before removing the legacy display.
