Honeywell Home RTH21B X2P Flex Schedule Programmable Thermostat, White

The Honeywell Home RTH21B X2P Flex Schedule Programmable Thermostat puts climate control in your hands with an intuitive push-button interface and customizable scheduling. This white rectangular thermostat works with most single-stage heating and cooling systems to deliver precise temperature management throughout your home, whether you're using gas, oil, electric forced air, or hot water heat. The backlit LCD display stays visible in low-light conditions, making it easy to monitor and adjust settings at a glance day or night.

Managing your home's comfort has never been simpler. The X2P Flex Schedule lets you create distinct schedules across seven days, including weekday and weekend options, so your heating and cooling automatically adapts to your routine. A dedicated vacation mode temporarily reduces HVAC activity while you're away, helping lower utility bills without sacrificing comfort when you return. The push-button layout eliminates complicated menus, making it accessible for all ages, and the neutral white finish complements any interior décor.
