This easy-to-operate 1-Week Programmable Thermostat allows you to precisely control the temperature in your home exactly when you want it. With the ability to customize your schedule with four options – 'wake', 'leave', 'return', and 'sleep' – this programmable thermostat provides added comfort and efficiency. Simple step-by-step instructions are included, making DIY installation a breeze.
Designed for one-week programming, this thermostat from Honeywell can save you significant money on your energy bills. By adjusting the temperature when you are away or asleep – times when optimal comfort is not necessary – your heating and cooling equipment will run less, resulting in substantial savings. The single program covers the entire week, with four distinct periods per day.
Simple and effective, this digital thermostat offers precise temperature control within 1 degree Fahrenheit. The intuitive interface and easy-to-read display provide one-touch access to adjust the setpoint temperature. The straightforward operation keeps programming simple, even for DIY installation.
To ensure reliable performance, this thermostat features built-in battery change reminders (2 AAA batteries required) and retains the setpoint in memory during power outages. Display options include Fahrenheit or Celsius, as well as 12 or 24-hour clock format. However, please note that this model does not have backlit display.
Versatile in its functionality, the thermostat is compatible with heating, cooling, and heat pump systems (without auxiliary heat). It does not work with electric baseboard heat (120-240 V), heat pumps with backup, or multi-stage heating/cooling systems. This thermostat is designed for indoor use only.
The permanent and temporary override capabilities allow you to easily adjust the temperature as needed, providing added convenience and control. With its one-week programming and precise temperature regulation, this Honeywell thermostat is an excellent choice for improving the comfort and efficiency of your home.
