We are now offering new HMI & FANC firmware versions (v1.07 & v1.10) for our LTR-1200.

Therefore, from now on, we will send all our new LTR-1200 quotations and order confirmations (and the resulting devices) with firmware versions (HMI FW v1.07 and FANC FW v1.10) as standard. Order confirmations with different versions as well as your existing specific customer requests will remain valid.

If you would like a different HMI / FANC firmware version, please contact our sales team.

The most important changes:

• The new FANC firmware supports the new fans that will be installed in the LTR-1200 in the future. We are changing the fans due to changes in the supply chain. The new fans have the same specifications as the previous ones; minor change in the fan control, no change in the application expected.
• The new HMI firmware version supports TEC Controllers with firmware version ≥6.20; please specify the desired firmware version of the TEC controllers when ordering in the future.
• The new HMI firmware version also enables support of the Meerstetter TEC Controllers TEC-1091, TEC-1161, TEC-1162, TEC-1163, TEC-1166, TEC-1167. Please note that these devices are not supported by the LTR-1200, a new standard solution is in the development pipeline. However, the HMI-1119 can already be used with these devices as part of individual customer projects.
• Various bug fixes

Supported devices:

• HMI-1119: HW version 0.50 – 1.21
• FANC-1118: HW version 1.00 – 1.31

More information on the firmware updates and the new features can be found in the HMI-1119 Software Release Notes (PDF) and the FANC-1118 Software Release Notes (PDF).

Update the LTR-1200

The firmware can be updated by yourself. To do this, download the latest HMI-1119 software package and the latest FANC-1118 software package from our website and install the firmware according to the instructions in the LTR-1200 Update Instructions (PDF)

Please note:

• An update is only required if you need the new functionalities (e.g. support of TEC Controller FW ≥6.20 or the new fan generation).
• If your system is running stably and you do not require these changes, we recommend not updating unnecessarily.

Attention: The new TEC Controller firmware version 6.20 is only compatible with HMI software version ≥v1.07. In addition, the new fans are only compatible with FANC software version ≥v1.10.
