What is Safety Protection?

Safety Protection is a feature that alerts you if the home gets too cold or too hot. This is set under the menu option on the setting for both low and high temperatures. The system will automatically turn on either cooling or heating if the home's interior temperature reaches either the low or high setting. A notification is also sent to the Home screen notification area and Lennox S40 Thermostat App.

To turn on the Safety Protection feature under Menu > System Settings > Heat & Cool > Safety Protection.
