I have installed a Powermaster 33 along with a KP 250 Keypad. After months of no problems, the keypad display is now showing "No Communication" whenever any button is pressed. There is therefore no possibility of entering Installer Mode etc..
Is it likely that the communication failure is due to the keypad, the module inside the Powermaster control box or is it possible to reset the comms between the keypad and controller somehow?
I would appreciate any help in resolving this matter.
Thanks in advance.
