Check the Cable: Ensure the 4-core relay module cable is securely connected at both ends and shows no signs of damage.
Power Cycle the System: Fully disconnect the main power loom from the IY-HUB2 unit, wait 10 seconds, and reconnect it. During a normal power-up, the relay board lights should turn on for 5 seconds and then turn off.
Check for Fault State: If all the channel lights on the relay board remain continuously lit after a power cycle, the board is likely faulty. Please contact Insytly Support for assistance.
