<p>A heat pump (11) and auxiliary heat (12) arrangement is disclosed for control of the environment in a closed space (17). A real time clock operated thermostat means (21) operates the heat pumpe and auxiliary heat. An actual temperature in the space and the slope of a defined curve establishes a correct starting point for the system so that a setback can be reversed with the temperature coming out at the desired temperature at a correct time. The present system uses no outside temperature sensor.</p> |
