## Questions & Answers

**Q: What is the distribution Id?**
A: The distribution ID is 11151

**Q: If there is a power outage will the clock reset automatically or have battery backup for the outage**
A: This unit design does not have a battery backup or has auto clock reset. When ever there is eletric current disruption, you must manually reset your clock, date, and day.

**Q: Does the screen backlight turn off automatically or is it always on?**
A: turns off automatically

**Q: I need a controller that switches 120v on when remote sensor a is < builtin sensor b, and sensor b > 70 degrees.  can this unit do it?**
A: No, I'm afraid this thermostat can't do the required task. You can either set remote (floor) sensor temperature settings or built-in (ambient) temp. settings. As soon as measured temp. on sensor that is set to be in control (floor or ambient mode) drops below settings, the controller will switch 120V or 240V on.
