After conversion, the Aga will be controlled by a series of dials located on a glass screen inside the control door of the Aga. The first dial selects the hobs. Hobs can be both on or can be selected individually. There is an eco setting, allowing the hobs to sit at a low consumption rate when additional room heat is required. We advise against continual use of the hobs to reduce running costs. Each hotplate has a further dial, allowing you to adjust selected temperatures. Both plates can be used for boiling, simmering or anything in between. For even greater flexibility, INSTAHEAT is available, replacing one hotplate with a ceramic ring, perfect for the summer months and for when immediacy is paramount. The remaining dials control the ovens. One selects from the preset functions – Eco, Normal or Full Ambient Heat Mode – and the remainder fine tune the temperature of each oven. The traditional roasting oven can be set to simmer, bake or roast, as can the 3rd oven in 3 oven models, whilst the traditional simmering oven can achieve up to baking temperature and beyond. On 4 oven models, a further switch allows the user to choose to turn the hotcupboard on / off independently of the hot side of the Aga.
