## Questions & Answers

**Q: How does the auto changeover work? can i set it to keep the temp between 65 and 74 degrees and it turns a/c and heat on as necessary?**
A: Yes I wasn't sure how it would work.  I have my account set to 78.  AC came on when it go too hot.  Hope this helps.

**Q: Hi. My old thermostat has the red wire connect to RH which then jumps to RC. With the Sensi lite, do I just attached the red wire to R? Thank you.**
A: Sensi claims there is an internal jumper which means you only have to connect the red wire which now goes to RH. However, I had to pigtail the red wire and connect to both RH and RC

**Q: Will this thermostat work on a split unit meaning natural gas heat**
A: It works on my natural gas central unit (if you need emergency heat then no this touch lite will not work for you)

**Q: Does this have a child lock?**
A: Yes, it’s called Lock Thermostat Display. It’s located in the system settings.
