Hey OP, can you take a photo of the whole of the front control panel? I would assume there is another control for timing the central heating and it might be underneath a cover.
What did your landlord tell you when you asked how to set the timer?

It looks like this is the the on/off for a combi-boiler; is that right, OP? I would assume there is a timer clock under a panel - a circle with tiny little switches that represent a half-hour or quarter-hour each.
