Sensor
When a unit is designed with CO2 control, CO2 sensor is
needed to be supplied at field. LG DOAS includes a
CFM modulation controls sequence based on CO2
value. The sensor must be mounted in the space at a
height of approximately five (5) feet from the floor.
Wiring between the Unit and the space CO2 sensor must
be through a field-supplied, three-conductor, 20 AWG,
and stranded communication cable.
Terminations must be made per the following chart.
