Hi I wonder if anyone could help with a problem . I have storage heaters with local controls for the heater. There is a key bord which I can use to turn the individual heaters off/ on. The controller has a name and part number on the back Apollo 56000-400. One of the soldered tracks on the circuit board has burned off and it cant be repaired. Does anyone know of this make and is it still available. The date of manufacture was 1991 as near as I can tell.
