(57) A timing control unit 100 for a heating and hot water system comprises a rotatable
knob 110 disposed within a ring of illuminable segments 120, Each segment in the ring
120 corresponds to a fifteen minute time interval during a day. A ring of numbers
130 is provided within the ring of segments 120 to indicate the hours of the day that
the segments 120 correspond to. In order to set activation periods for the heating/hot
water, a user selects a start time by rotating the knob 110 to the desired start of
the activation period; pressing the knob 110 to select the desired start of the activation
period; rotating the knob 110 to the desired end of the activation period, and pressing
the knob to select the end of the desired activation period. Whilst setting the activation
periods, the time interval segment currently selected by the knob is indicted by being
illuminated intermittently.
