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.
