User Operation
The display indicates CO
2
in PPM, temperature in °F or °C,
%RH, temperature setpoint in degrees °F or °C and override
using the BAPI Man icon. The three triangle icons are used
with the –ARW option to show CO
2
levels.
The main display indicates the numeric value of the quantity
being displayed. The minor display indicates the engineering
units of the value, such as PPM, °F, °C or %RH.
Temperature Setpoint Slidepot:
Moving the slidepot enough
to change the setpoint by one degree will display the setpoint
on the main LCD 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 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.
