How to code and configure a remote control for the Comfort 257.2 operator?
To code a new transmitter, use a transfer plug to connect it to a master transmitter; hold the master button and then the new button until the LED stays lit. The operator must be reprogrammed to recognize the new code. Specific button assignments, such as intermediate positions or specific open/close functions, can be configured through Level 4 of the advanced programming. Ensure the door's movement area is clear during operation.
