What to do if the green LED is OFF on my Honeywell Controller?
If the green LED is off on your Honeywell Controller, it indicates the Ethernet port link is down. First, check the cable connection between the controller and the switch. Then, check the switch itself. As a test, directly connect the controller to the switch using a known good laptop or cable.
How to fix Honeywell Controller when both LEDs are OFF?
If both LEDs are off on your Honeywell Controller, it means there is no communication over the interface. Use ComfortMan to check the interface assignment in the application. Also, check the wiring.
What does it mean if the green LED is ON on my Honeywell Controller?
If the green LED is ON on your Honeywell Controller, it means that Ethernet connectivity exists but there is no data flow. Check the software configuration.
Why is the yellow LED ON steadily on my Honeywell Controller?
If the yellow LED is ON steadily on your Honeywell Controller, it means the Ethernet is working with connectivity below 100Mbps. If communication problems persist, check the green LED.
What does it mean if the green LED is flashing on my Honeywell Controller?
If the green LED is flashing on your Honeywell Controller, it indicates normal operation. The controller is transmitting/receiving data to/from the switch via cable. If communication problems persist, the Ethernet parameter configuration may be defective. Check the IP address, MAC address, and firmware.
What to do if the yellow LED is OFF on my Honeywell Controller?
If the yellow LED is OFF on your Honeywell Controller, and the green LED is ON or flashing, then Ethernet is working with connectivity below 10Mbps. If the green LED is OFF, then Ethernet is disconnected. Connect the cable between the controller and the switch.
