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.

By programming your thermostat and taking advantage

of the times that a building is unoccupied or the

occupants are asleep the thermostat can reduce heating

and cooling bills by as much as $150. 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.

MESSAGE CENTER

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

and the name of the current event if running the temperature

program. 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 Digital Humidifier

Control (Model 58) and Humidifier the message center will also

inform you if the humidifier is operating.

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 Digital Humidifier

Control (Model 58) or an Aprilaire®Model 6504 Intelligent Zoned

Comfort 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 temperature(s) 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 generally 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.

Notes on Temperature Adjustments

The Cool setting must always be 2° or 5° (F or C)

higher than the Heat setting. The value (2° or 5°) is

selectable. The thermostat will automatically change

the temperature setting not being adjusted to maintain

this difference even if both settings are not shown on

the display.
