SVA – Smart VAV Actuator
The Smart VAV Actuator (SVA) is an application-specific Single Duct VAV controller for controlling the temperature in an area served by a VAV box. The SVA adopts the latest VAV technology, thus providing a more flexible control and greater reliability than the traditional VAV Controllers. The integrated brushless constant speed motor used in the SVA controller has a much longer lifetime than the standard brushed motor. The built-in air velocity pressure sensor has a high accuracy AD converter, which allows for accurate VAV air balancing. An external 10k Temperature sensor is available for installation.
The SVA controller contains a library of pre-programmed pressure-dependent and independent VAV boxes applications so that no additional user programming is required. For it to be fully functional, the operator needs to choose the most suitable pre-programmed application while setting the SVA device address. to ensure device addresses are unique on the same network and set the required temperature, minimum and maximum airflow rate set-points.
The SVA has a very unique automatic integration time process control function that senses the magnitude of the process control variable offset and compares the duration of the integration time to modulate the control signal so that any permanent process control variable offset is completely eliminated to ensure optimum building environment comfort and energy usage.
The SVA can be operated as a stand-alone or networking mode, and it supports a communication speed of up to 76.8k baud which allows rapid access to the information within the whole HVAC system.
The SVA can be connected to Smart Touch Screen (STS-SVA) to provide local and remote monitoring or controlling.
