Reposition the device to be within the range of the Wireless Receiver. For information on typical transmission ranges, refer
to the Open-to-Wireless Application Guide.
Using the device configuration plug-in or wizard, check the configuration of the input. Refer to the Wireless Battery-less
Sensors and Switches Solutions Guide for more information.
1. Ensure the tubing is installed properly and that the tubing is not bent.
2. Verify that the high and low pressure sensors are not inversed.
Recalibrate the controller. Refer to the controller's user guide for more information.
The two mechanical stops must be positioned to stop the damper motion when it is completely closed and completely
opened. The mechanical stops can be moved by increments of 5°.
Set the Override to OFF in the wizard.
Data is not being received from the BACnet MS/TP data bus.
Data is not being transmitted onto the BACnet MS/TP data bus.
Initialization: The device is starting up.
Firmware upgrade in progress. Controller operation is temporarily unavailable. The new firmware is being loaded into
memory. This takes a few seconds. Do not interrupt power to the device during this time.
The controller is operating normally.
The device has not received a BACnet token, and therefore cannot communicate on the network: Verify that the controller's
MAC Address is unique on the BACnet MS/TP Data Bus – see Device Addressing. Make sure the controller's BAUD rate is
the same as the BACnet MS/TP Data Bus' BAUD rate (see Setting the BAUD Rate (optional)). Verify that the Max Master is
set high enough to include this controller's MAC Address (See the Network Guide).
Poor-quality power; The device has browned-out: The voltage at the 24VAC and 24VCOM terminals has gone below the
device's acceptable limit during power up.
Invalid MAC address: The device's MAC address is set to zero (0) or is set to an address higher than the Max Master. See
the Network Guide, or for the ECB-VAV UUKL controller, refer to the Distech Controls UUKL Smoke Control System Design
Guide.
