Manual mode allows you to set a specific temperature that will be maintained until changed. In Eco mode, you can set the desired setpoint temperature, which will flash while saving. Program mode can be overridden by selecting a different mode at any time. It is more economical to avoid letting temperatures drop too low in frequently used areas. Recommended overnight setback temperatures are no lower than 14°C. Daytime temperatures should be set at 16°C and above.
