Neutral zone electronic room thermostat
The device can set an adjustable neutral zone from 0 to 11 °C. For example, setting the thermostat at 21 °C, with a 2 °C neutral zone, will have the effect that below 19 °C the heating will automatically turn on, while above 23 °C the air conditioning will turn on, while between 19 °C and 23 °C nothing happens.
The thermostat is available in 230V and 24V versions.
