The blue light is off and lights up when I turn on my kitchen sink hot water tap. At one stage this light was on all the time but after a heating engineer attended to the boiler this changed and now I am querying what is the correct thing regarding this blue light?
MT 10 Safety Instructions B These instructions must be observed to ensure proper functioning of the timer. B The timer should only be fitted by an approved installer. B The timer must not be connected to the 230 V mains supply.
