The Côr® 5 Thermostat is a user-friendly, programmable device at our most attractive price point. This wall-mounted, low-voltage unit is 7-day, 5/2-day and 1-day programmable. There’s no need for batteries to store user-configured settings within its memory. During power loss, its internal memory saves settings for an unlimited time, and the clock continues to run for at least 12 hours. Programmable scheduling allows you to easily customize settings for times when you’re home, sleeping or away. You can set your schedule for four periods per day (Wake, Away, Home and Sleep) or two periods per day (Wake and Sleep).
