Honeywell's 5-1-1 Day Programmable Thermostat let's you program weekdays separate from Saturday and Sunday.
The 5-1-1 Thermostat is a very easy-to-use programmable thermostat with intuitive logic that responds to your choices and schedule for optimal comfort and energy savings. The menu-driven programming makes it simple. The large, backlit display shows room temperature, set temperature and current time all at once. It features precise comfort control of +/-1°F for maximum comfort.
This thermostat is compatible with heating and cooling plus some heat pumps. It does not work with heat pumps with back-up heat, multi-stage heating/cooling systems, and electric baseboard heat (120-240V).
