This user-friendly 1-Week Programmable Thermostat is designed to make your home comfortable precisely when you need it. Featuring a programmable weekly schedule, it allows you to customize your settings with four options – 'wake', 'leave', 'return', and 'sleep' – for precise temperature control and enhanced comfort. The simple step-by-step instructions provided with the thermostat make DIY installation a breeze.

A Honeywell programmable thermostat can significantly reduce your energy bills. By adjusting the temperature when you're away or asleep – times when optimal comfort isn't necessary – your heating and cooling equipment will run less, leading to substantial savings. This single-piece thermostat offers a single, user-friendly program for all days of the week, with four daily periods: wake, leave, return, and sleep. Its simple and effective design ensures reliable performance.

Crafted from durable plastic and imported for your convenience, this thermostat offers a range of features:

ONE WEEK PROGRAMMING: Set a single, identical program for the entire week, with four daily periods (wake, leave, arrive, sleep). PRECISE TEMPERATURE CONTROL: Accurately maintains temperature within +/- 1 degree Fahrenheit. DIGITAL DISPLAY: Easy-to-read digital display with an intuitive interface for quick access to temperature setpoints. EASY INSTALLATION: Simple DIY installation and straightforward operation for hassle-free programming. REMINDERS: Built-in battery change reminders (2 AAA batteries required for operation). SET POINT RETENTION: Retains temperature setpoints in memory during power outages. DISPLAY OPTIONS: Supports Fahrenheit or Celsius, and 12 or 24-hour clock formats. (Note: This thermostat is not backlit.) OVERRIDE OPTIONS: Allows for both permanent and temporary temperature overrides. COMPATIBILITY: Works with heating, cooling, and heat pump systems without auxiliary heat options. (Not compatible with electric baseboard heat, heat pumps with backup, or multi-stage heating/cooling systems. For indoor use only.)
