Page 28

NOTE: Refer to the Owner’s Manual for thermostat operating instructions.

1.PLACE THE THERMOSTAT ON THE BASE.

2.TURN ON POWER TO THE HVAC SYSTEM.

The display will show the Aprilaire screen for approximately 5 seconds (up to 10 seconds if installed as part of a Model 6504 Intelligent Zone System).

After this initial screen the thermostat will enter operational mode.

3.VERIFY OUTDOOR TEMPERATURE SENSOR CONNECTION (if optional outdoor temperature sensor installed).

If an outdoor temperature sensor has been installed and is operational, an outdoor temperature will appear on main display.

4.CHECK FAN OPERATION

• Turn on the fan (set to ON).

The thermostat G terminal will energize and the system blower will start. The Fan Status on the display will show “FAN ON.”

If an AHC has been installed, allow the fan to operate for no less than 40 seconds. If an AHC is not part of this installation, you can turn the fan off at any time. A humidity value can be displayed only after at least 40 seconds of blower run-time to ensure the humidity reading is representative of the room air.

Turn the fan off (set to AUTO).

5.VERIFY AHC CONNECTION (if optional Automatic Humidifier Control installed).

Ensure that the AHC has power (the green status light on the AHC should be on) and make sure the AHC is functioning properly – see AHC installation procedure for start up and diagnostics.

From the Main Screen, press the “INFO” button.

The outdoor temperature and relative humidity will be displayed for five seconds after which the contact screen will be displayed (see page 33 for additional information on the contact screen).

When the humidifier is operating, the message “HUMIDIFIER ON” appears at the message center, alternating with the time and date and any other currently active messages.
