Span is the temperature difference between the turn on
temperature and turn off temperature. 0.5ºC or 1ºC of span can be
selected and the effect is summarized in the following table:
Span Heating System Cooling System

Ts: Set temperature
Tr: Room temperature
For example, if you set the temperature to 20°C and span = 1, the
heater will operate when the room temperature drops to 19.6°C and
turns off when the temperature rises to 20.4°C
