The setback value allows the set temperature to be altered only by the difference compared to the standard temperature, to help save energy.
Example: When the standard temperature is 24°C and the setback value is 2°C.
During operation as a cooler, the set temperature is 24°C + 2°C = 26°C.
During operation as a heater, the set temperature is 24°C - 2°C = 22°C.
