ENERGYSTAR^®PROGRAM INFORMATION (Programmable Models Only)

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

®

home. If you’ve selected 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 Models 8363, 8365 & 8366 have

earned the “ENERGYSTAR^®” 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

ENERGYSTAR label.

ENERGYSTAR products help you differentiate between standard efficiency and

high efficiency products. By using ENERGYSTAR 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 ENERGYSTAR 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 ENERGYSTAR partner, Aprilaire has determined that this product

meets the ENERGYSTAR guidelines for energy efficiency.

PROGRAM EVENTS

Your thermostat has 5/2 (5 weekdays and 2 weekend days) programming

functionality, which allows the user to set four events for the weekdays

(Monday through Friday) and two or four events for the weekend (Saturday

and Sunday). The events are WAKE, LEAVE, RETURN and SLEEP. If you are

normally home on the weekend, you can set up your thermostat to use only

2 events (WAKE and SLEEP) on Saturday and Sunday.

WAKE is the time and temperature setting you desire when you wake in the

morning. The event should include extra time for the heating and cooling

equipment to heat or cool the house to a comfort level prior to getting out of bed.

NOTE: It will take some time for your heating or cooling system to reach

the desired temperature when returning from 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 WAKE event to 6:00 AM

to be sure the desired temperature is reached by 7:00 AM.

LEAVE is the time and temperature setting for the daytime hours you are

away from the house and wish to reduce the heating or increase the cooling

temperature for energy savings.

RETURN is the time and temperature setting for the evening hours.

SLEEP is the time and temperature setting for your sleep hours.
