I have recently had installed an Ariston Genus combi-boiler. I have re-set the timer on the programmer (Horstmann) to switch on only at 7pm but the boiler is on when I get up at 7.30. Even when the programmer is set to OFF, rather than AUTO, the boiler still fires. It seems as if the default setting for the morning is still operating. Is this a programmer or a boiler fault and how can I remedy this?
