The Honeywell RTH7500D is a basic programmable thermostat for the average home user. The system is simple enough that home owners are encouraged to install it themselves, with step-by-step instructions in the manual. 7-day programmability allows a separate program to be set for each day of the week, enabling people to account for times when they are out of the house. Smart Response Technology adjusts pre-heating and cooling accordingly. This can save up to 33 percent on annual heating and cooling costs. The display is backlit to enable reading in low light, and indicates the time, date, temperature, and if its time to change the filter. This thermostat is compatible with regular heating and cooling, as well as heat pump systems. It does not, however, work with electric baseboard heat (120-240V).
