AHU First-time Setup

  1. Run Channel Setup Wizard To Configure Analogue Outputs.
  2. Run Channel Setup Wizard To Configure Analogue Inputs.
  3. Run AHU Discover Wizard.
  4. Configure AHU Control Points.
  5. Assign A Schedule To The AHU.

The following steps define how to set up an AHU for the first time. If you would like to amend the settings of an AHU that has already been configured, see the AHU Configuration guide.

To set up an AHU for the first time, begin by discovering and configuring a WEMScontroller3, using the Auto Discover Wizard and Channel Setup Wizard. The WEMScontroller3 is ideally suited to controlling an AHU because of its 4 analogue outputs (3 of which are configurable) and 2 analogue inputs. One WEMScontroller3 is needed per AHU.

In addition to the steps above, the AHU setup requires that the system is able to measure the Outside Air Temp and the internal room space temperature. Existing temperature sensors can be used to provide these measurements.

The following process must be performed BEFORE attempting to use the AHU Discover Wizard.
