About half of all energy used by households goes to

heating and cooling the home. By selecting a program-

mable Aprilaire®Electronic Thermostat, you have made

a significant step toward conserving energy usage and

costs, while improving your indoor comfort.

In fact, the Aprilaire®Model 8570 Premium Programmable

Thermostat has 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.

MESSAGE CENTER

Normally this is where you will find the current date and time.

If the thermostat is in a Hold State, the thermostat will display

when the Hold State is scheduled to end. The area is also used

to give information on when you should replace your air filter or

UV lamp, when you should service your humidifier and general

HVAC equipment.

When installed with an Aprilaire®Automatic Humidifier Control

and Humidifier, the message center will also inform you if the

humidifier is operating.

When installed with an Aprilaire®Model 6504 Intelligent Zone

System, more information is displayed in this area. For instance,

if you own an Energy Recovery Ventilator (ERV), or an Electronic

Air Cleaner (EAC) the thermostat will be able to display whether

they are active.

EQUIPMENT STATUS

In this area of the display, the thermostat will show the

equipment’s mode and whether the equipment is active. A typical

message in this area would be HEAT MODE when the equipment

is not running and HEATING when the equipment is active.

OUTDOOR TEMPERATURE

The thermostat has terminals that can be hooked up to an

outdoor temperature sensor. If this is installed, outdoor

temperature will be displayed in this area of the screen.

When installed with an Aprilaire®Automatic Humidifier Control

or an Aprilaire®Model 6504 Intelligent Zone System, this

information is communicated to the thermostat so there is no

need for the extra outdoor temperature sensor.

ROOM TEMPERATURE

The large temperature on the screen is the room temperature.

The scale can be changed from Fahrenheit to Celsius if desired.

SETPOINTS

The setpoints are the temperatures to which the thermostat

is controlling.

MULTI-FUNCTION BUTTONS

The multi-function buttons are used throughout the thermostat

menu system and have many functions. The description on the

screen directly above the button is what that button is used for in

that particular screen. In Figure 1, the left button would be used

for INFO and the right button would be used for MENU.

UP/DOWN BUTTONS

These buttons are used to raise and lower temperature and to

navigate through the thermostat’s menus.

OPERATING YOUR THERMOSTAT

Backlight Operation

When any button is pressed, the backlighting will

illuminate. Once the backlight is on, subsequent button

presses will perform their respective tasks.

Using the Up & Down Buttons and Multi-Function

Buttons on the Thermostat

This thermostat uses a menu driven display and four (4)

buttons. The Up and Down buttons are used to move

between selections in the menu and to raise and lower

different parameters such as temperature, days,

minutes etc., depending on which screen you are

viewing. The multi-function buttons have a variety of

uses. The portion of screen directly above these

buttons will display the button’s function. For instance,

when the main screen is being viewed, the buttons are

titled INFO and MENU from left to right respectively.

To access the menu of the thermostat, press the right

multi-function button. From here if you would like to

change the fan operation, press the down button until

the word FAN is highlighted, then press the

multi-function button titled SELECT (right button).

Within this screen, use the up and down button to

highlight the desired fan operation and press SELECT

again and you are done.

Notes on Temperature Adjustments

The Cool setting must always be 2° (F or C) higher than

the Heat setting. The thermostat will automatically

change the temperature setting not being adjusted to

maintain this 2° difference, even if both settings are

not shown on the display.

1. Setting the Mode of Operation – Heat, Cool, etc.

The thermostat can be set to OFF, HEAT, COOL, AUTO and EMERGENCY HEAT (EMERGENCY HEAT

for heat pumps only) modes. To set the mode, press the MENU button on the main screen.

Once in the Main Menu screen, use the down button to move the highlighted text to MODE.

Press SELECT. Once in the Mode Menu, use the Up/Down Buttons to navigate to the desired mode,

then press SELECT.

Example: Placing thermostat in HEAT MODE.

2. Temporarily Raising and Lowering the Temperature

You can raise or lower the temperature during the current event of the program by simply

pressing the Up/Down buttons.

Example: The Setpoint is at 68°, you want the temperature to be 72°.

If you are in AUTO Mode, both heat and cool settings will be displayed on the hold screen.

First you can change the Heat setting, then the Cool setting. If you do not want to change one

of these settings, simply press select to go to the next setting or to go to the main screen.

The message center displays when the thermostat will return to programmed operation.

Press the RESUME PROG. button to return to programmed operation at any time.

3. Fan Operation

The thermostat can operate the fan in 3 ways:

• AUTO (on only during heating and cooling calls)

• ON (always on)

• PROGRAMMED FAN (fan follows the program set in the program screen)

The FAN MENU, located in the MAIN MENU, has these three options for you to choose from.

NOTE: When installed with an Aprilaire®Model 6504 you will be given the option to CHANGE ALL

THERMOSTATS. If you select YES to this, the fan setting will be set to whatever you have selected for

all the thermostats on the system.
