## Questions & Answers

**Q: How did everyone else get the red wire in if it is so tightly screwed in? I can’t seem to get it to budge, even with the correct size screwdriver.**
A: I used a small flathead that fit in the slot. Then used pliers on the shaft of the screwdriver. I used the pliers to turn the screwdriver and I was able to loosen the screw

**Q: Where can I find an owners manual?**
A: Jeezus people, if the person is asking isn’t it obvious he does not have it in the box?!! The least helpful answers ever. I inherited the thermostat from a previous owner and in search for a manual, too. Guess what— no box!!

**Q: How do I put it on. I cannot program it**
A: Hi, thank you for reaching out with this. We would like to gather some more information on your specific system so that we can provide assistance on how to program. Please reach out to our support team on Facebook/Twitter with a private message. We look forward to hearing from you soon. -Jim

**Q: does this thermostat use a battery for power? and how long should the battery last if it needs one**
A: Hi there, this thermostat requires 2 AAA batteries, battery life depends on the usage, we recommend replacing batteries at least every year. - Maria
