Configure FP AHU Control Points

  1. Auto Discover WEMScontroller4.

  1. Click the new FP AHU icon, which will present the FP AHU Control Screen.

The icon should look like that of a standard AHU with a red spot to indicate that the Object has not been configured. For more information on other icon statuses that are possible for FP AHUs, see FP AHU Icon Statuses.

    2. The Outside Air and Space Temp dropdowns need to be configured using existing outside air and room space temperature sensors. All other selections required on this screen are based on the relays and analogue inputs that were automatically created after the WEMScontroller4 was discovered and the Auto Build button was pressed.

The topmost slot of the 4 Space Temp dropdowns must be populated in order for the room space temperature to act as a valid temperature reference. Filling the other 3 slots can allow the system to use temperature averaging, depending on which Temperature Mode has been selected.

Set the FP AHU control points

To edit the settings in the Info Panel and to edit the setpoint values in the graph at the bottom of the screen, use the Advanced button. For more information on how these settings work, see FP AHU Configuration.

FP AHUs do not use a Schedule in the way standard AHUs do, as they are designed to be in an always-on state. See the FP AHU Configuration section for a guide on configuring the block graph at the bottom of the screen.

  1. Once all settings have been adjusted as required, click Save to confirm the choices and then Close to return to the Floorplan.
