## Questions & Answers

**Q: Can this be used for a gas insert fireplace?**
A: Yes, it is a millivolt thermostat. It takes two wires from the gas fireplace.  There is a safety strip you have to remove to activate the thermostat.

**Q: Is this setup to handle AUX heat?**
A: Hi Gilbert, this is a millivolt thermostat that can control a single stage heat only system. You can contact our tech support team at (800) 468-1502 or through social media and we will be happy to recommend you a thermostat compatible with Aux heat. - Maria

**Q: What is the lowest temperature it can be set at without being in the off position? I need it as a low limit to hold around 40 degrees.**
A: The lowest is about that.

**Q: Is the off position really off, or just the lowest setting?**
A: Hi Chris, thank you for reaching out! The Off system setting at the thermostat will ask the HVAC system to go off. If you need further assistance, contact us at 1-800-468-1502, or through Facebook and Twitter under Honeywell Home.- Charlie
