Instructions need help
Instructions need help. Not for a dyi. You definitely need experience. I am a talented individual and I struggled with multiple things. For example the wired control units were very misleading where to connect them. There needs to be instructions fir each different model not just a vague blanket instruction. They work great. Delivery was great. I was missing screws to the faceplate of the ceiling cassettes. Other than that I had everything needed.
