Nibe Display Units 718337 and 718255 are indeed compatible with a wide range of Nibe heat pumps and indoor modules. These units are sold as hardware-only replacements—meaning they don’t come with pre-installed software, so uploading the correct firmware is essential after installation.

Here’s a quick breakdown of the compatible models:

• Heat Pumps: F370, F470, F730, F750, F1145, F1155, F1245, F1255, F1345 (across various kW ratings)
• Indoor Modules: VVM 310, 320, 325, 500
• Control Modules: SMO 20, SMO 40

If you're planning a replacement or upgrade, make sure the software version matches your system’s requirements.
