    Fig. 3. Mounting the wallplate.3.Remove the wallplate from the wall and drill two 3/16
    inch holes in the wall (if drywall) as marked. For firmer
    material such as plaster, drill two 7/32 inch holes.
    Gently tap anchors (provided) into the drilled holes until
    flush with the wall.
    4.Position the wallplate over the holes, pulling wires
    through the wiring opening.
    5.Loosely insert the mounting screws into the holes.
    6.Tighten mounting screws.
    WIRING
    All wiring must comply with local electrical codes and
    ordinances. Follow equipment manufacturer wiring
    instructions when available. Refer to Fig. 15 and 16 for typical
    hookups. A letter code is located near each terminal for
    identification. Refer to Table 4 for terminal designations.

    System and Fan Settings
    The system default setting is Heat and the fan default setting
    is Auto. Use the System and Fan keys or switches to change
    the settings. See Fig. 8. The fan settings can be set for each
    program period individually. The system selection is for all the
    program periods.
    System settings control the thermostat operation as follows:
    Em Heat: Emergency heat output is controlled as Stage 1
    heat. Cooling system is off. Compressor is de-
    energized.
    Heat: The thermostat controls the heating.
    Off: Both the heating and cooling are off.
    Cool: The thermostat controls the cooling.
    Auto: The thermostat automatically changes between
    heating and cooling operation, depending on the indoor
    temperature.
    Fan settings control the system fan as follows:
    On: Fan operates continuously.
    Auto: Fan operates with equipment.
    INSTALLER SETUP
    NOTE: For most applications, the thermostat factory
    settings will not need to be changed. Review the
    factory settings in Table 6 and if no changes are
    necessary, go to the Installer System Test section.
    The Installer Setup is used to customize the thermostat to
    specific systems. Some of the options include temperature
    display, changeover and outdoor temperature display. Installer
    Setup numbers are listed in Table 6. The table includes all the
    configuration options and the factory settings for the
    thermostat.
    A combination of key presses are required to use the Installer
    Setup feature.
    —To enter the Installer Setup, press and hold the Information
       i   key with the increase â–² and decrease â–¼ keys until the
    first number is displayed. All display segments appear for
    approximately three seconds before the number is
    displayed. See Fig. 9 and 10.
    —To advance to the next Installer Setup, press the Time ▲
    â–²
    key.
    —To change a setting, use the increase ▲ or decrease ▼
    key.
    —To scroll the Installer Setup numbers backwards, press the
    Time â–¼
