Room heating control unit compares actual temperature with reference setting and provides for two operating temperatures dependent upon a timer

摘要

The heating of a room (3) is controlled by a unit that compares actual temperature (4) with two reference settings (6,9). One of these (9) is a higher value and is only effective when a timer (7) allows input to the controller (1). This allows a higher heating temperature to be generated at specific times of day.
