ENERGY STAR^®Program Information

About half of all energy used by households goes to heating and cooling the

home. By selecting a programmable Aprilaire^®Electronic Thermostat, you

have made a significant step toward conserving energy usage and costs,

while improving your indoor comfort.

In fact, the Aprilaire Electronic Thermostat Model 8554 has earned the ENERGY STAR designation of

the U.S. Environmental Protection Agency (EPA). This means that your Aprilaire Thermostat is a highly

efficient, cutting edge product that is good for the environment. It saves energy and costs less to

operate than similar products that do not qualify for the ENERGY STAR label.

ENERGY STAR products help you differentiate between standard efficiency and high efficiency products.

By using ENERGY STAR Star products you are helping to prevent air pollution while saving money on your

utility bills.

According to the EPA, taking advantage of the times that a home is unoccupied or the occupants

are asleep, an ENERGY STAR thermostat can reduce heating and cooling bills by as much as 30%. The

Aprilaire Thermostat has programmable capabilities that allow you full flexibility to set your heating

and cooling systems to meet your comfort and energy needs. As an ENERGY STAR partner, Research

Products has determined that this product meets the ENERGY STAR guidelines for energy efficiency.

Setting Or Changing The Program

Programming your Aprilaire Electronic Thermostat involves selecting the temperature you want in your

home and selecting the time you want it to be that temperature. Your Aprilaire Thermostat will allow a

maximum of 4 time schedules per day. Each time schedule is known as an “event.” The Morning event

is typically when you wake up and is the first event of the day. The Day event is typically set when you

leave for work. The Evening event is typically set when you come home from work and the Night event

is set when you go to bed. Each event will have 2 temperatures, 1 heating temperature and 1 cooling

temperature. The cooling temperature must be at least 2 degrees higher than the heating temperature.

Your Aprilaire Thermostat allows 1 program for Monday through Friday and 1 program for Saturday and

Sunday. Complete the chart on page 7 with your desired temperatures and time schedules before

beginning programming.

Progressive Recovery

Your Aprilaire Thermostat is equipped with a programming feature called “Progressive Recovery.”

This feature assures that your house will economically achieve the desired comfort temperature at

the programmed time when returning from an economy or setback temperature. For example, if you

like a wake-up temperature of 68°F at 6:00 AM from a setback of 65°F it is not necessary to set the

morning program for 5:00 AM. The thermostat will automatically start warming your house in advance

so your comfort temperature is reached on time.The progressive recovery feature must be activated

in order to work.

To activate the progressive recovery

mode simultaneously press the

PROGRAM and FAN buttons. A small

thermostat icon, “

“, will appear

under the clock. Once in this mode

proceed with programming your

thermostat remembering to use exact

times for each event time change.

NOTE: If not using Progressive Recovery, it will take some time for your heating or cooling system to

reach the desired temperature when returning from a setback. Therefore, it is suggested you set your

program time before the actual time you want your home to reach the desired temperature. For example,

if you get up at 7:00 AM and have a 6 degree setback, set your Morning event at 6:00 AM to be sure the

desired temperature is reached by 7:00 AM.
