Sigma 02 Adjusting central heating flow temperature Central heating water temperature is adjusted by rotating the control knob (fi g. 5 ). Rotate the knob clockwise to increase water temperature, anticlockwise to reduce water temperature. Temperature can be varied from a minimum of 60°C to a maximum of 8 °C.
