Description
York S1-03109182000 VAV/Economizer Expansion Control Board Module is used to control economizer, and variable air volume operations in HVAC systems in rooftop units and air handling equipment. It operates by taking input signals on sensors and controllers and sending outputs to dampers and other related parts to control airflow and outside air intake. It is set up as an expansion module, and is linked to the main control board, and system wiring to operate in coordination. This allows proper control of airflow and energy-efficient ventilation and allows the system to remain stable.
