The Robertshaw® RS4000 Value Series nonprogrammable thermostats are designed with Pop-Up Wizards to customize thermostat settings with an instant startup menu. According to the company, the units significantly reduce installation and setup. The series includes one heat-one cool and two heat-two cool models, and are fully compatible with all standard heating and cooling systems. Features include an easy-to-read, backlit digital display that shows the room temperature, set point temperature, and which system is running; security lockout; memory retention; adjustable temperature differential and upstaging; and low-temperature freeze protection that turns on heat automatically when the temperature goes below 41°F.
