Understanding Trane Economizers
What Is an Economizer?
An economizer is a device that allows a building’s HVAC system to use outside air for cooling when conditions are favorable, reducing reliance on mechanical cooling systems like air conditioners. By leveraging outdoor air efficiently, economizers contribute significantly to energy savings and improved indoor air quality.
Types of Trane Economizers
Trane offers various economizer models tailored to different building requirements:
- Air-Side Economizers: Introduce outside air directly into the ventilation system.
- Water-Side Economizers: Use cooling towers and heat exchangers to reduce mechanical cooling needs.
- Hybrid Economizers: Combine both air-side and water-side features for optimal performance.

Operational Settings and Control Configuration
Understanding Control Logic
Trane economizers operate based on a set of control logic that determines when to open or close dampers:
- Temperature and humidity sensors assess outdoor air conditions.
- Mixed air temperature sensors monitor indoor conditions.
- Damper actuators adjust airflow accordingly.
Proper configuration ensures maximum energy savings while maintaining indoor comfort.
Configuring the Economizer via Manual
Steps typically include:
- Setting minimum and maximum damper positions
- Defining outdoor air temperature thresholds for economizer operation
- Adjusting humidity limits to prevent excessive moisture entry
- Calibrating sensors for accurate readings
- Programming override controls for safety
Refer to the specific Trane manual for detailed instructions tailored to your model.
