This may appear a newbie question.
I got a new colored viewstat and never used before. I just need the AxLink power source or I need an aux power supply.

This is a case where you do not use the Axlink Power. So leave the '+' unconnected.
The T-Stat gets it's power from the HVAC unit. I myself am still skeptical about this as I've had many an Aprilaire and AMX viewstat blown up by a jittery HVAC guy.
Having said that, I asked the AMX tech support folks and they assured me that it's now okay and that the new color T-Stats can take the beating.

I take it a step further. I use a dedicated, backed up power supply of my own for all thermostats in a system.

How well does that work when the customer has an hvac problem not related to the automation system? A truck roll every time? I've had several jobs with other mfgr's tstats where we had to show up because the hvac tech couldn't figure out why it didn't work...Like it not being wired properly at the unit. Yup, definitely our fault on that one.
