Antares timer manual/instructions?

My central heating runs off a Fagor FE-24E boiler and is controlled from a wall-mounted timer in the lounge. Which I have no instructions for! All I can tell you is that it is labelled 'Antares', and is a full 7-day type. It has a long button beneath the display which scrolls between 4 settings ('1', a clock symbol, '2' and a 4th unrecognisable symbol) and has 4 square push buttons labelled with 'P', a clock, '1-7' and a thermometer symbol down the right hand side. Does anyone recognise this? Can someone please point me at a manual or otherwise instruct me? Many thanks. Please reply direct to barrycroft@yahoo.co.uk
