The Honeywell T5 thermostat with flexible programming provides great energy savings and a comfortable home. With a 7-day schedule (5-2 days), or weekly programming, it automatically transitions from heating to air conditioning and vice versa. In the event of a power outage, this device retains your program in memory. The thermostat can installed as a battery-powered or wired unit. It is equipped with a low battery warning, a 12 or 24-hour time display and a sleek touchscreen with cool blue backlight for easy reading of temperature and humidity levels. The clock is connected in real-time and automatically adjusts for daylight savings time, while the smart response learning system analyzes your selections and provides the right heating or cooling temperature at the right time for you. The thermostat is compatible with most systems and comes with a 1-year limited warranty.
