KEYPAD CONFIGURATION

Allows further configuration of system to desired application such as whether th unit displays in °F or °C, whether the display shows the set point or room air temperature, and to set controls for sensor biasing. Changes do not take affect until power is

cycled on the unit.

To enter Keypad configuration

Cycle power to unit. Press and hold the Fan Speed Button and the COOLER button for 5 continuous seconds, within 30 seconds of the unit being powered up. If the unit has had power for more than 30 continuous seconds, keypad configuration cannot be entered. When keypad configuration mode is first entered, it will default to Fahrenheit/ Celsius Display Mode.

To scroll through the Keypad Configuration Options

Press and release the Fan Speed button. The stored value will be displayed.

To modify configuration settings

Press and release the Setpoint Up or Setpoint Down buttons.

To exit Keypad Configuration

Keypad Configuration will end on its own 30 seconds after the last button is pressed or when the MODE button on the Key-

pad is pressed.

In the configuration mode, four different options can be selected by using the fan speed button. The options are described below:

Fahrenheit/ Celsius Display Switch:

Changes between degrees Fahrenheit and Celsius on the display. An “F” indicates Fahrenheit and ‘C’ indicates Celsius. De-

fault is degrees “F”.

Indoor Air Temperature Sensor Biasing for Cooling mode:

Sometimes known as an anticipator, the air temperature sensor bias is used to adjust the room air temperature reading in

cooling mode. (Not normally required.)

Indoor Air Temperature Sensor Biasing for Heating mode:

Sometimes known as an anticipator, the air temperature sensor bias is used to adjust the room air

temperature reading in heating mode. (Not normally required.)

Indoor Temperature Display:

Change between showing setpoint only on the display during heating and cooling modes “SP” or displaying

room temperature during heating and cooling modes “AA”. (“SP” mode is the default mode.)

If “SP” is selected, only the setpoint will be displayed during heating and cooling modes, regardless of what the real

temperature is in the room.

If “AA” mode is selected, the room temperature will be displayed during heating, cooling and fan only modes.

—If the mode button has been changed to either heating or cooling modes, setpoint will be displayed for 10 sec- onds. After the 10 seconds, the room temperature will again be displayed.

—If the on/off button is pressed (when the unit is off) and the last mode was either cooling or heating, the setpoint will be displayed for 10 seconds before displaying room temperature.

—During heating and cooling modes, if either the up or down setpoint key is pressed, the display will show the setpoint until 10 seconds after the last up or down key is pressed. Then the room temperature will be displayed again.

To restore factory setting

During standby of OFF mode, press fan speed and UP buttons simutaniously for 3 seconds. The display will show “00” for 3 seconds.
