Apartment building zoning solution - Tekmar tn2?
It's regarding zoning my house, a multi-family building in Boston.
There are 5 stories and We live on the bottom 2 floors so technically there are 4 units. There're baseboards throughout the building, so, one temperature, one zone, powered by a viessmann boiler, vitodens 200. In addition , I have an indirect tank, on priority. There is no separate control system other than the one builtin in the boiler.
My goal is to be able to control the temperature on each floor with sensors and zone valves on each floor. My initial plan is to get the tn2 house control 400, 4x indoor sensors, 4x 518 thermostats, 4x zone valves. My first question is, am I on the right direction? Also, the 400 offers some redundant features, such as outdoor reset, since my boiler is already doing the modulating. My second question is how do they coexist or whether I can disable the modulating in my boiler and let the 400 do it all?
Any advice will be greatly appreciated.
Thank you in advance!
