how to hook up thermostat

It was time to add a remote controlled HVAC thermostat. I had reviewed many options over the last few months and ultimately I decided on the Filtrete 3m50 Wi-Fi Touch Screen Programmable Thermostat with Remote Access wow that is a long name. Why did I pick this one? The 3m50 comes with the Wifi version but you can also purchase Z-wave and ZigBee modules. The controller actually has room for two USNAP modules but I have no clue what the benefit would be to the two radios. Why did I not go with Z-wave? Lazy — All the software is ready to go. Cost I can always do it later. Most of the new thermostats are power hungry. If you are replacing an older thermostat that uses batteries or one of the old school mercury thermostats, you will have to hook up 24vac power to make the USNAP modules work.
