Honeywell Home RTH2510B1018 7-Day Programmable Thermostat – Precise 1°F Control & Flexible Scheduling

7-Day Scheduling for true daily flexibility

When your daily routine isn’t the same from week to week, the Honeywell Home RTH2510B1018 offers independent programs that you can tailor for each day. With four program periods per day—wake, leave, arrive, and sleep—comfort settings can align with individual schedules, helping you stay comfortable on your terms rather than a generic timetable.

Precise comfort at a glance This thermostat provides accurate temperature control within ±1°F, so you can enjoy steady comfort without constant readjustments. The backlit digital display and intuitive interface make it simple to view and set the target temperature, even in dim lighting or from across the room.

• Separate daily programs for wake/leave/arrive/sleep
• Accurate ±1°F temperature control
• Backlit display for quick visibility
• Manual override anytime for immediate adjustments

Maintenance, timing, and memory

The Early Start Function helps ensure the programmed temperature is reached by the scheduled time, so rooms feel comfortable when you expect them to. Built-in reminders prompt you about battery and filter changes, and the unit retains its programming if power is interrupted.

• Early Start ensures temperatures reach the set point on time
• Reminders for battery and filter changes
• Programming retention during power outages
