This relay is replaced by a semiconductor relay.
The relay is pin compatible to the KACO relay and has the same size. By replacing the defective KACO relay, the system, which has a respectable efficiency, is revived.
This saves the purchase of a new controller or even heating.
The replacement of this relay has often been successfully used in practice.
The type RS75001L1-1A controls the burner of the Viessmann automatic control unit (relay K1).
This is a semiconductor relay for a max. current of 8A.
If you have problems replacing the relay, contact your local specialist or send us the control unit.
We will take care of this for you.
