    Why is the “PWR” LED not lighting up on my Orion Control Systems Controller?
    • M
      Michael NealAug 5, 2025
      If the “PWR” LED on your Orion Control Systems Controller doesn't light up, ensure the modular connector is properly connected to the board, the connections are secure, and the connector tab is locked. Also, verify that the power is connected to the Power/Comm board and the modular cable connector is securely attached. If the LED still doesn't light up after these checks, the board may be defective.

      To resolve an invalid temperature reading from the Space Temperature Sensor on your Orion Control Systems Controller, first ensure the modular cable connector is firmly plugged into both the board and the Space Temperature Sensor. If you're using a cable coupler, make sure it's also firmly connected. If the problem continues, try replacing the sensor with a known working one.

    What to do if the “REC” LED does not flicker on my Orion Control Systems Controller?
    • T
      Tracy SmithAug 28, 2025
      If the “REC” LED on your Orion Control Systems Controller isn't flickering, check the MiniLink PD and/or CommLink connected to the Power/Comm board, which is connected to your VAV/Zone Controller. Ensure that the MiniLink and/or CommLink is powered on and properly connected.
