| How do Hunches work? | When your phone leaves your home area and nobody interacts with Alexa for a while, Alexa might have a hunch nobody’s home. If no one interacts with Alexa for a while at night, she might have a hunch everyone is asleep. When someone interacts with Alexa or uses smart devices, she can tell that someone is home. Alexa learns from your daily interactions and improves over time.

You can also help Alexa know when you go to bed or leave home by saying, “Alexa, goodnight.” or “Alexa, I’m leaving.” |

## Questions & Answers

**Q: Can I hook multiple thermostats and one household to one account? I have three HVAC units**
A: Yes, presently I have three seperate thermostats and adding another to a singe account.  Each controls a separate hvac unit.

**Q: My RC  terminal has a jumper wire to the RH terminal as well. How do I wire my Smart thermostat**
A: Y terminal=Yellow wire 
G terminal=Green
C terminal=Blue wire
W terminal=White wire
R terminal=Red wire    On the bottom right hand of the new thermostat wiring terminal there is a blue switch that slides up and down, slide it to the up position. This is the position of the switch for the jumper wire application
I hope this is helpful, please feel free to contact me, good luck

**Q: I have an old three wire thermostat (yellow, white and blue) will it work or need anything additional for installing this?**
A: If you have a 3 wire cable, it won’t work unless you have a heat only home. 
You would need the add a wire adapter or run a new thermostat 5 or 7 wire cable

**Q: Can you set specific times for the heat to turn on or off?**
A: Yes. The app makes it easy to set a schedule with preferred temperatures for each of the following: “Away”, “Home”, and “Sleep”. You can also adjust the temperature outside of that schedule and it will hold until the next scheduled change. You can set it to “Auto” (which keeps the temperature between preferred cook and heat songs), “cool”, “heat”, or “off”.
