Precision Digital Controls sells and installs the ASIC/1 family of preprogrammed controllers for HVAC management. They have built in control sequences to cover most equipment configurations, and optional features to extend control to cover common applications.

Pre-programmed VAV Controller with integrated actuator

The ASIC/1-6000 pre-programmed digital controller is an integrated VAV controller and actuator.  Suitable for pressure-independent of pressure-dependent applications, can be used with electric heat, hot water valve reheat, and fan powered boxes.

  • Integrated damper actuator, onboard calibrated airflow sensor
  • Lighting control, variable user adjust, trending, afterhours overide, auto-changeover...
