## Questions & Answers

**Q: Does it come with a 4wire to 5 wire adaptor to “ create” the C wire for power to thermostat?**
A: Yes. Everything is there

**Q: do you need to purchase the bracket to mount the thermostat or can you do it without it?**
A: The Ecobee 4 comes with mounting screws and screw anchors.  I've installed three Ecobees in my home and have not needed a special bracket.  It also comes with a suitable back plate to cover up any holes left by a bigger thermostat.

**Q: Does it have a battery backup? I got rid of my Ecobee3 because it would lose its mind and not come back after a power failure.**
A: Not a changeable battery, but there is a coin-cell back up battery.

**Q: How many sensors can you connect to one ecobee4?**
A: Looks like you can pair up to 32 sensors to the Ecobee 4.
