The network variable output communicates outdoor
air damper status (0 to 100% open) of the device.
This network variable output communicates the out-
door air temperature in degrees Celsius to other
devices. The valid range is from -40°C to 100°C with a
resolution of 0.01°C.
This network variable output communicates the space
CO2 concentrations in parts-per-million to other
devices. The valid range is from 0–2000 ppm with a
resolution of 1 ppm.
This network variable output communicates the space
temperature in degrees percent to other devices. The
valid range is from 0% to 100% with a resolution of
0.005%.
This network variable output communicates the space
relative humidity in degrees Celsius to other devices.
The valid range is from -15°C to 50°C with a resolution
of 0.01°C.
This network variable communicates unit status infor-
mation to other devices.
Binary Bind to this network variable input to communicate
the discharge air cooling setpoint in degrees Celsius
to the device. The valid range is from 0°C to 30°C with
a resolution of 0.01°C.
Bind to this network variable input to communicate
the discharge air heating setpoint in degrees Celsius
to the device. The valid range is from 10°C to 70°C
with a resolution of 0.01°C.
Bind to this network variable input to communicate
the duct static pressure in Pascals to the device. The
valid range is from 0 Pa to 1250 Pa with a resolution
of 1 Pa.
Bind to this network variable input to communicate
the duct static pressure in Pascals to the device. The
valid range is from 0 Pa to 1250 Pa with a resolution
of 1 Pa.
Binary Bind to this network variable input to communicate
economizer operation enable or disable to the device.
Bind to this network variable input to communicate
emergency overrides to the device.
Bind to this network variable input to communicate
the application mode to the device.
