AP-VMA1220-0

The Johnson Controls AP-VMA1220-0 variable air volume, or VAV, controller is an extremely effective and all-inclusive solution for finely controlling airflow in HVAC systems. Its integrated design combines an actuator, pressure sensor, reheat feature, and fan power choice into a single pack to simplify installation and save costs. By providing sophisticated control capabilities, the AP-VMA1220-0 controller aims to guarantee maximum comfort and energy efficiency in a variety of commercial and industrial areas. Precise control and monitoring of the ventilation system are made possible by the built-in actuator, which precisely modifies damper locations in accordance with specified airflow setpoints. In order to adapt to various climatic circumstances, the reheat feature enables precise temperature control by modulating the reheat coil. In order to ensure optimum air distribution and circulation, the fan power choice operates a ventilation fan. The AP-VMA1220-0 controller is very adaptable since it works with common cooling features and reheat, and it can be used with single-duct systems, parallel systems, and series fan-powered boxes. Because it is pre-assembled, the controller's installation is fast and simple, and its sophisticated diagnostic functions enable better system monitoring. The AP-VMA1220-0 can tolerate temperatures of between -40 and 158 degrees Fahrenheit while being stored, and it runs at a supply voltage of 20 to 30 volts AC. This VAV controller is long-lasting and dependable in HVAC applications since it is housed in sturdy plastic. Overall, the AP-VMA1220-0 is designed to provide accurate airflow control, energy efficiency, simple installation, and maximum comfort in a variety of HVAC systems.
