The following messages may be seen on the Keypad LCD due to Bus or ID problems:.
\"No Bus Communications\"
This means that the Keypad is not receiving Mesages on the RS485 Bus. This should be due the wiring from the keypad to the Comfort controller being wrongly connected, particularly the KA/KB wires.
\"ID Not Polled\"
This means the RS485 Bus is connected but the Keypad ID is not polled. Press F9 to check what is the Keypad ID. Make sure the Keypad IDs are consecutive and have no missing IDs. Right Click on the Modules Tab and Do a Scan for All Modules in Comfigurator to detect all the modules in the Bus.
\"ID Conflict Detected\"
This may be due to a duplicate Keypad ID in the system, or it may have the same causes as \"ID Not Polled\". This may also be caused by a faulty wiring from the keypad KA/KB to the Controller.
\"RS485 Communications Failure Keypad # X\"
Keypad IDs should be consecutive eg if there are 6 Keypads, they should have IDs running fro 1 to 6 with no missing IDs. Missing IDs will cause \"RS485 Communications Failure\" Message
Note:
Most problems are caused by wiring. A good test is to remove the keypad from its mounting, unplug the Terminal Blocks, and connect the Keypad directly to the Comfort controller by a short cable. If the problem does not occur then the issue is the wiring.
Most problems are caused by wiring. Everybody insists the wiring is correct, but in the end, it is always the wiring! Dont forget to check the Terminal blocks as the contact may bot be good or not tightened over the conducting oart of the wire

Hi Support,
Today, I replaced my Keypad 02 with a new one because the old one speaker is damaged. After replaced, the new Keypad screen displays \" ID01, ID Conflict Detected\" What shall I do to rectify?
When I do Scan for all modules, it shows not found. Now it shows Keypad not Poolled.
Regards

Each keypad must have a different ID. If you have 2 keypads with ID=1 that means both keypads cannot be polled. The KP04 manual shows how to change the keypad ID. download from https://www.cytech.biz/kp04a_keypad_with_lcd_white.html
Change one of the keypad ids to 2.Press F0 6789# on the keypad, then press F to end then press and hold * until the menu appears on the keypad LCD

The keypad ID can also be changed using Comfigurator as shown in this post http://www.comfortforums.com/forum105/4357.html
