Access 4.x

Manual control


The functions of the Access controller can be switched to "manual" mode during testing and commissioning. If any of the functions such as fan, heating/cooling sequence, damper, input, or output are set to manual mode, an alarm indication will be displayed.


Caution: Manual control should exclusively be employed for testing and commissioning activities.



The available manual control options are as follows:


  • Inputs can be manually set to replicate the required values of connected sensors, transmitters, or switches.
  • Outputs can be manually activated to control components, indicators (DO), and adjust speed or capacity (AO).
  • Fans can be manually operated at specific levels, setpoints, or output values.
  • Heating/Cooling sequences can be configured to achieve the desired outputs from connected peripheral devices.
  • Modbus-controlled actuators (dampers) can be manually set to move and lock at desired positions.
