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
®
Model 8570 Premium Programmable
Thermostat has earned the “E
NERGYSTAR
®
” 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 E
NERGYSTAR label.
E
NERGYSTAR products help you differentiate between
standard efficiency and high efficiency products. By
using E
NERGYSTAR 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
E
NERGYSTAR 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 E
NERGYSTAR partner, Aprilaire has
determined that this product meets the E
NERGYSTAR
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.
CAUTION: Do not set to OFF mode during periods when freezing temperatures could occur.
NOTE: When installed with an Aprilaire
®

THERMOSTATS. If you select YES to this, the mode setting will be set to whatever you have selected
for all the thermostats on the system.

2. Temporarily Raising and Lowering the Temperature
You can raise or lower the temperature during the current event of the program by simply

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.
