The display indicates VOC in PPM, air temperature in degrees Fahrenheit or Celsius, relative humidity in %RH,
temperature setpoint in degrees Fahrenheit or Celsius and override using the BAPI Man icon. The three arrow
icons are used with the –ARW option to show VOC levels and their meaning.
The main display indicates the numeric value of the quantity being displayed. The minor display indicates the
engineering units of the value, such as VOC, °F, °C or %RH.
Temperature Setpoint Slide Pot:
Moving the slide pot enough to change the setpoint by one degree
will display the setpoint on the main display if equipped with display.
The setpoint display will hold for five seconds after moving the slide
pot.
Override Button:
When the override button is pressed on display units, the BAPI Man
icon will display. A dry resistance of less than 1 Ohm appears from
the override output (OVR) to the Ground terminal (GND). Latching
the BAPI Man icon to show that the system is in override requires
that a dry contact on your controller be used to connect terminal
EXT to ground.
