The TQ-D32 air quality transmitters are designed to control fresh air flow in air conditioning systems. Two different models are available.
TQ-D32-CO2 determines the air quality through measurement of CO2 concentration (ppm).
The output signal can be used to control fresh air fans and dampers according to the ventilation load. It is equipped with a single output which automatically determines whether to run in current or voltage mode, no more jumpers or switches to worry about.
