Why is my Distech Controls Controller not turning on even though it's powered?
- S
  scottrossAug 18, 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 ECL/ECB-600 wireless devices are not working correctly?
- C
  Carrie GrahamAug 23, 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.

What to do if Distech Controls ECL/ECB-600 Controller does not communicate on a large network?
- B
  brianmartinNov 4, 2025
  If your Distech Controls Controller communicates well over a short network but fails on a larger one, consider these potential issues: * **Network length:** Ensure the total wire length does not exceed the specifications outlined in the Network Guide. * **Wire type:** Verify the wire type matches the specifications in the Network Guide. * **Network wiring:** Double-check all wire connections to ensure they are correct. * **Network termination:** Check the network terminations, as incorrect or broken terminations can affect communication integrity based on the controller's position on the network. * **Number of controllers:** Ensure the number of controllers on a channel does not exceed 50. If it does, use a router or a repeater. * **Max Master parameter:** Configure the maximu...

What to do if Distech Controls ECL/ECB-600 Controller hardware output is not operating correctly?
- M
  Monique WheelerNov 8, 2025
  If a hardware output on your Distech Controls Controller isn't working correctly, consider the following: * **Blown Fuse:** If it's a 24V controller with an auto-reset fuse, disconnect the power and output terminals, wait a few seconds for the fuse to cool down, check the power supply and output wiring, and then reconnect the power. * **Wiring Issues:** Verify the output wiring is correct, referring to the module's hardware installation manual and the peripheral device's manufacturer specifications. * **Configuration Problems:** Use EC-gfxProgram to check the output configuration to ensure it is enabled. * **Actuator Problems:** If using a 0-10V output with a 24VAC powered actuator, check the polarity of the 24VAC power supply connected to the actuator. Reverse the 24VAC wire if n...

What to do if Distech Controls Controller hardware input is not reading the correct value?
- J
  Jennifer HughesNov 13, 2025
  If a hardware input on your Distech Controls Controller isn't reading the correct value, here's what to check: * **Wiring:** Ensure the wiring is correct, following the module's hardware installation manual and the peripheral device's manufacturer's recommendations. * **Circuits:** Use a voltmeter to check the voltage on the input terminal. For a digital input, a short circuit should show approximately 0V, while an open circuit should show approximately 5V. Correct the wiring if there's a fault. * **Configuration:** Verify the input configuration using the controller configuration wizard. * **Voltage/Current:** An over-voltage or over-current at one input can affect other input readings. Ensure you're respecting the allowed voltage/current range limits for all inputs. Check the ap...

What to do if Distech Controls Controller device does not communicate on the BACnet MS/TP network?
- S
  Stephanie CherryNov 26, 2025
  If your Distech Controls Controller isn't communicating on the BACnet MS/TP network, consider these potential causes: * **Voltage Issues:** For 24V controllers, check for 'Poor-Quality Power' status, verify the power supply voltage is within 24VAC/DC ±15%, and check for tripped fuses or circuit breakers. * **Transformer Overload:** For 24V controllers, check for 'Poor-Quality Power' status and ensure the transformer is powerful enough. * **Wiring:** Double-check wire connections. * **Termination:** Check network terminations. * **Max Master Parameter:** Configure the Max Master to the highest MAC Address of any device on the MS/TP data bus. * **Duplicate MAC Address:** Ensure each controller has a unique MAC Address. If the MAC Address DIP switch is set to 0 (all off), use an ...
