SYSTEM CONFIGURATION
CON (Continuous)
Allows fan to run continuously, circulating air even when the temperature setting has been satisfied. This switch
helps to maintain the room temperature closer to the thermostat setting.
CYC (Cycle)
This setting allows the fan to cycle on and off with the compressor or electric heater. The fan stops a short time
after the temperature setting is satisfied.
Set point Temperature Limits
Provides a restricted range of temperature control.
Room Freeze Protection
O
If unit senses a room temperature below 40 F, the fan motor and electric strip heat will turn on and warm the
O
room to 50 F. The fan stops a short time after the temperature is satisfied.
KEYPAD CONFIGURATION
Keypad Configuration
Allows further configuration of system to desired application. 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 Set point Up or Set point Down buttons.
To exit Keypad Configuration
Keypad Configuration will end on its own 30 seconds after the last button press or when the MODE button on the
Keypad is pressed.
Fahrenheit/ Celsius Display Switch:
Change between degrees Fahrenheit and Celsius on the display. An "F" indicates Fahrenheit display and "C"
indicates Celsius. Default 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 when 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 when in heating mode. (Not normally required.)
Indoor Temperature Display:
Change between showing set point 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 set point 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, set point will be displayed for 10
seconds. After the 10 seconds, the room temperature will again be displayed.
* If the on/off button is depressed (when the unit is off) and the last mode was either cooling or heating mode, the
set point will be displayed for 10 seconds before displaying room temperature.
* During heating and cooling modes, if either the up or down set point key is depressed, the display will show the
set point until 10 seconds after the last up or down key press. Then the room temperature will be displayed again.
SYSTEM CONFIGURATION
DIP SWITCHES
Auxiliary dip switch controls are located behind front
panel, through an opening below the control panel.
To access, remove front panel.
Dip switches are accessible without opening the
control box. Unit must be powered OFF to effectively
change their status.
Factory settings for dip switches will be in the DOWN
position.
Functions for functions of each dip switch position.
Electric Heating Only / Emergency Heat (For heat Pump Units Only)
This setting is typically used for Emergency heating.
Wall Thermostat Enable
A wired wall thermostat can be connected to the unit. If it is, this dip switch must be moved to the Wall.
Thermostat Enable Position, before the wall thermostat will begin control.
Heat and Cool Fan CON/CYC Dip-switches
Allows the fan to operate in continuous or cycle modes while the unit is in heating or cooling mode (continuous or
cycle).
