The ER message on the CoolBot display is an indication that there is an error or issue with the sensor cable. When the Mode light blinks rapidly, it signifies that there is a problem with the cable that is currently plugged into the Fins port.
To resolve this issue, you need to check the sensor cables and make sure they are properly connected. Start by unplugging the cable that is currently plugged into the Fins port. This cable is most likely the ROOM sensor cable.
After disconnecting the ROOM sensor cable, you can discard it as it is likely the cause of the error message. The display will still show “Er” because there is nothing plugged into the Room port. However, this is not a cause for concern as long as the FINS sensor is properly connected.
If you have a replacement sensor cable available, you can now plug it into the Fins port. This new cable will serve as the replacement for the faulty ROOM sensor cable. Make sure the connection is secure and tight to ensure proper functioning of the CoolBot.
In some cases, the error message may still persist even after replacing the sensor cable. This could indicate a more serious issue with the CoolBot itself. In such situations, it is advisable to seek professional assistance or contact the manufacturer for further guidance.
To summarize the steps to resolve the ER message on the CoolBot display:
1. Unplug the cable currently connected to the Fins port, which is likely the ROOM sensor cable.
2. Discard the faulty ROOM sensor cable.
3. If available, replace the faulty cable with a new sensor cable.
4. Ensure the new cable is securely plugged into the Fins port.
5. If the error message persists, consider seeking professional assistance or contacting the manufacturer.
Personal experience: I have encountered the ER message on the CoolBot display in the past. Initially, I was unsure about the cause of the error and what steps to take to resolve it. However, after carefully examining the sensor cables and following the instructions provided by the manufacturer, I was able to identify and fix the issue. It turned out that the ROOM sensor cable was faulty and needed replacement. Once I replaced the cable, the error message disappeared, and the CoolBot resumed normal operation.
