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?

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.

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.

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

Will this thermostat work on a split unit meaning natural gas heat

It works on my natural gas central unit (if you need emergency heat then no this touch lite will not work for you)

Does this have a child lock?

Yes, it’s called Lock Thermostat Display. It’s located in the system settings.
