APPLICATIONS The ASIS/1-5000C series controllers contains the most frequently used VAV applications and has personalities for cooling only, heating only and cooling with hot water or electric reheat, and constant or intermittent fan. The ASIS/1-5000C series controllers can operate stand-alone or provided the RS-485 communicating interface and Modbus protocol for system integration.

GENERAL The ASIS/1-5000C series integrated VAV controllers is a pre-programmed communicating digital controller, with or without an integral damper actuator for the control of pressure independent Variable Air Volume (VAV) and Fan-Powered VAV terminal units. The controller maintains the space temperature by varying the air volume and includes an on-board airflow sensor. The controller monitors zone temperature through a temperature sensor or WS series zone temperature sensor and calculated the correct air volume to be distributed to the space by comparing the zone temperature with the cooling and re-heating setpoints. The ASIS/1-5000C series controllers to be fully operational, the operators needs only to enter a unique device address, select the appropriate personality for the application, and verify or modify duct area and airflow K-factors. No user programming or calibration is necessary. Pre-tuned PI algorithms mean that controllers can accurately maintain zone temperature.
