What to do if Distech Controls ECB-VAV-N Controller is powered but does not turn on?
- C
  Courtney SimsAug 21, 2025
  If the Distech Controls Controller is powered but does not turn on, it might be due to a blown fuse or incorrect power supply polarity. Disconnect the power and check the fuse integrity, then reconnect the power. Also, verify that consistent polarity is maintained between all controllers and the transformer, ensuring that the 24VCOM terminal of each controller is connected to the same terminal on the secondary side of the transformer.

What to do if hardware output is not operating correctly in Distech Controls ECB-VAV-N?
- J
  Janet RossAug 26, 2025
  If the Distech Controls Controller's hardware output is not operating correctly, it could be due to a blown fuse (auto-reset fuse), an output wiring problem, or a configuration issue. To resolve this, disconnect the power and output terminals, wait a few seconds for the auto-reset fuse to cool down, and then check the power supply and output wiring. Reconnect the power. Also, check that the wiring is correct according to this manual and according to the peripheral device’s manufacturer. Using EC-gfxProgram, check the configuration of the input. Refer to the EC-gfxProgram user guide for more information.

How to troubleshoot when hardware input is not reading the correct value in Distech Controls ECB-VAV-N Controller?
- I
  ibowersAug 28, 2025
  If a hardware input on the Distech Controls Controller is not reading the correct value, check the input wiring to ensure it is correct according to this manual and the peripheral device’s manufacturer. Using EC-gfxProgram, check the configuration of the input. Refer to the EC-gfxProgram user guide for more information. Be aware that an over-voltage or over-current at one input can affect the reading of other inputs; respect the allowed voltage/current range limits of all inputs. Consult the appropriate datasheet for the input range limits of this controller. Finally, use a voltmeter to check the voltage on the input terminal. For example, for a digital input, a short circuit shows approximately 0V DC and an open circuit shows approximately 5V DC.

What causes flow sensor to not give proper readings with Distech Controls ECB-VAV-N?
- D
  Dave LeeSep 1, 2025
  If the flow sensor is not giving proper readings with your Distech Controls Controller, ensure the tubing is installed properly and that it is not bent. Also, verify that the high and low pressure sensors are not inversed.

Why is my Distech Controls ECB-VAV-N not turning on even though it's powered?
- A
  Alejandro CaldwellSep 9, 2025
  If your Distech Controls Controller is receiving power but not turning on, there could be a few reasons. Here's what to check: * **Blown Fuse:** If it's a 24V controller, the fuse may have blown. Disconnect the power, check the fuse, and reconnect the power. * **Power Supply Polarity:** Make sure that consistent polarity is maintained between all controllers and the transformer. Ensure the COM terminal of each controller is connected to the same terminal on the secondary side of the transformer. * **Insufficient Power:** If it's a 24V controller, the transformer may not be powerful enough. Verify that the transformer used is powerful enough to supply all controllers.

What to do if Distech Controls ECB-VAV-N wireless devices are not working correctly?
- J
  Juan FischerSep 12, 2025
  If wireless devices associated with your Distech Controls Controller aren't functioning as expected, consider the following troubleshooting steps: * **Device Association:** Verify that the device is associated with the controller using the device configuration wizard. * **Power:** Recharge the device with light if it's solar-powered, or replace the battery if it's battery-powered. Also, ensure sufficient light intensity (200lx for 4 hours/day) for solar-powered devices. * **Distance:** Reposition the device to ensure it's within range of the Wireless Receiver. * **Configuration:** Check the device configuration using EC-gfxProgram to ensure it's enabled.
