Description
The Honeywell W7212A1017/B Economizer Logic Module is a control unit used to regulate the intake of outdoor air for cooling. It evaluates temperature and humidity condition, then directs dampers to open or close based on whether outside air can support cooling demand. Installed in rooftop units and air handling equipment, it assists maintain balanced airflow and stable indoor conditions in HVAC systems. This module acts as the decision-making point between sensors and damper controls, allowing the system to shift between outside air use and mechanical cooling as operating conditions change.
