... we have just started renting a house with a Biasi Riva Plus M90D.24S combi boiler. No instructions - can anyone, please, help with details of setting the timer 1-7 buttons along top; on/off button; +/- buttons and red slider with clock/Cl/auto/timer; and "enter" button. At the moment using room stat but with LPG think this will prove ££££ly. TIA
