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 “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, by programming your thermostat and taking advantage of the times that a building is unoccupied or the occupants are asleep, an ENERGYSTAR 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. As an ENERGYSTAR partner, Aprilaire has determined that this product meets the ENERGYSTAR guidelines for energy efficiency.

EQUIPMENT STATUS OUTDOOR TEMPERATURE ROOM TEMPERATURE MESSAGE CENTER SETPOINTS UP/DOWN BUTTONS MULTI-FUNCTION BUTTONS 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 Humidifie Control (Model 58) or an Aprilaire® Model 6504 Intelligent Zon Comfort System, this information is communicated to the thermo 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 fo that particular screen. In Figure 1, the left button would be us 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. 2

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. 4 1.
