Im planning on putting my HVAC on automation. My builder wants to use the Tekmar 557 (new, same as 552, but with a few more bells). I'd have a few of these in my house. They can be interfaced to several automation systems, via a tN4 controller. He likes these due to the controllers internal programming to adjust humidity and temperature based on inside, and outside feed back. If it changes inside, it adjusts. If it senses a temp drop, and humidity increase outside, it throttles up hear, and cuts humidity.
The system will be a 6-7 zone infloor heat system. (he thinks six inside, plug garage) with AC. Is there a better thermostat? Or would it be better to just put sensors in the zones and let home automation do it?
