Specs & Pricing

How ventilation controllers fit into HVAC systems

Ventilation controllers manage air handling processes using data from sensors such as temperature, humidity, and air quality measurements. Based on this data, they control field devices like fans, dampers, and actuators to regulate airflow and operating modes.

When connected to monitoring or building automation systems, ventilation controllers also enable alarms, trend monitoring, and centralized management across one or multiple buildings.

Air handling units (AHUs)

Centralized ventilation systems in commercial buildings

Ventilation systems in residential multi-dwelling buildings

Ventilation system upgrades and renovation projects

Relevant for:

System integrators and building automation contractors

HVAC manufacturers and OEMs (AHU builders)

Property owners and facility managers operating centralized ventilation
