Just moved into the house, previous occupant has lost boiler timer instructions. It's a Worcester Bosch 28Cdi combi boiler, with electronic timer number 77161920030. This timer is obsolete, can't find any instructions online, Worcester Bosch have not replied to repeated emails. There are many videos online showing how to programme other timers but not this one. The controls look different from anything shown in videos.
There are five buttons labelled SET? (one button) YES (two buttons labelled + and -. ADVANCE and SELECT. The display is labelled at side OFF, TWICE, ONCE, and ON. At present the display shows time and correct day of week with arrow pointing to TWICE
I'm reluctant to simply use trial and error as I've no idea what TWICE and ONCE means in this context.
