Can anybody help ?
Just bought a 1970 era house with the given control unit. Boost is for only one hour. I am unfamiliar with this unit, but have just pulled the instructions off the web. If I turn boost anticlockwise to START, I do not get a light showing. If I manually continue to turn anticlockwise, the boost light goes on for a fraction of a second and then goes out. Net result is I cannot get boost on, and therefore no hot water.
I don't know if it's relevant, but when I got the keys to the house I was informed that the power to the house had gone. This was resolved quickly by Scottish Gas replacing the MAIN fuse to the house. No idea if this would have caused problems for the Horstman control unit.
Any ideas anyone please ?
