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.

PRODUCT FEATURES

• Large, easy to read, backlit display.

• Simple programming with 4 events

for weekdays and selectable 2 or 4

events on the weekend.

• Pre-programmed with ENERGYSTAR‚

recommended settings.

• Set point and room temperature

are displayed simultaneously.

• Freeze protection.

• Low battery indicator.

• High temperature protection

(Models 8344, 8348, 8363 and 8366).

• Temporary and permanent

(vacation) hold.

• Change Water Panel indicator.

• Change air filter indicator.

• Fahrenheit/Celsius selectable.

• Adjustable differential.

OPERATING INSTRUCTIONS

COOL

In the COOL mode, the thermostat

will control the cooling system and

maintain your cooling set point.

NOTE: There is a 4-minute delay

after a cooling call is completed.

This is to protect the equipment’s

compressor from short cycling.

OFF

In the OFF mode, the thermostat

will not operate the heating or

cooling equipment. The FAN switch

can be placed in the ON position to

operate the fan continuously.

CAUTION: Do not set to OFF

mode during periods when freezing

temperatures may occur.

HEAT

In HEAT mode, the thermostat will

control the heating system.

NOTE: There is a 4-minute delay

after a heating call is completed on

heat pump models 8346 & 8365. This

is to protect the equipment’s

compressor from short cycling.

E-HEAT (MODELS 8346 & 8365 ONLY)

In E-HEAT mode, the thermostat will

activate the emergency heat with

any heat call. (Note-the AUX light in

the upper left hand corner of the

thermostat will illuminate any time

there is a call for Emergency Heat

or Auxiliary Heat. )

PROGRAM FOR HEATING AND COOLING

As part of the ENERGYSTAR program, your thermostat has been

pre-programmed with the following times and temperatures, which can be

modified as desired (see page 7).

AUTO

In the AUTO setting, the fan

operates only when the heating or

cooling equipment is on.

In the ON setting, the fan will

operate continuously.

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.
