Can you recommend a compatible alternative? Thank you. January 10, 2024 at 1:52 pm #4746 Khris JamesModerator Certainly! Based on your requirements, I recommend the FMM-101 as a suitable replacement for your System Sensor M501M. It offers similar functionality and should work seamlessly in your system. If you have any more questions, feel free to ask. Author Posts Viewing 2 posts - 1 through 2 (of 2 total) You must be logged in to reply to this topic.
