I have two Infinity systems in my house using the older -B Infinity Zone Control thermostats. I have remote access and home automation capability through an Infinity SAM. It works just fine but i want the Touch.

My question is, if i upgrade to the Touch thermostat, do i need to get the wifi capable units or can i by the non-wifi capable units since i can already see the stats over wifi through the SAM?

If i must get the wifi units, do i need to use both of the supplied routers, or can i use just one, or even better, just use my own router (with the same port forwarding if necessary)? In that case, how can i buy just the Touch stat with no router?

And lastly, am i foolish to think all Infinity equipment is capable with the Touch?

Thx for your advice!
