Figure 1: Digital Display Zone Sensor
The digital display zone sensor has the
functionality of the full-featured Trane
DDC zone sensor with a liquid crystal
display (LCD). The zone sensor is
compatible with Trane VAV and VariTrac
controllers. The display can be toggled in
the field from zone temperature to zone
setpoint and can be viewed in either
Fahrenheit or Celsius. A communications
jack is provided for Trane portable edit
terminal devices. Additionally, the On/
Cancel buttons allow the system to run in
the occupied mode during nighttime
operation. The ability to override to
maximum and minimum airflow or
position for field balancing is included in
the sensor. Please visit
contact a local Trane representative for
more information.
