I am working with an HOA with nearly same criteria but older General controllers and my suggestions were Virginia mh3000, Alpha, or MCE. Those HMC1000's are a solid controller. I see lots of them and they have little to no issues. Two alphas just hit the ground in 3-4 weeks from time of order (impressive turnover).
Maybe someone else here could confirm but Im not sure if the HMC1000 has DLM programming.
