TEMPERATURE CONTROLLERS - GENERAL When deciding on the best position for the temperature controls, the following points should be taken into account. • Fit the controls out of reach of children. (suggested height from the floor 1.5m) • Avoid positions where the controllers will become hot e.g. near stoves, ovens and heaters. • If possible, avoid exposure to direct sunlight or positions where bright lights will make the digital display difficult to read.
