Ferolli combi boiler - I pressed the wrong button?
I was trying to fix the water temp on my parents' central heating boiler and touched the + and - buttons and the one between that I now find is marked engineers only. The thermostat on the hall now reads of and there are no readings on the hot water side of the display. How can I fix it?
Thanks I downloaded the manal. Turned it off and on and reset. Seemed to do the trick thanks.

Your info regarding the thermostat is vague,however lets deal with your buttons. These have two roles, by pressing the +/- together the boiler is forced into a 15mins flat out burn so that the flue gases can be analysed so you haven't activated this.The other use is a bit long winded but it applies to OTC outside temp compensation which is an optimising set-up to adjust the room aumbience whilst looking at the outside temp. If you have OTC the right hand corner of display shows the temp and data during set up Press M once and a number 0-10 appears use +/- buttons and set this to 0 which puts OTC off normally 9or10 required in UK. Try this for starters otherwise download manual to learn more regarding the topic.
