Abstract

A clock operated thermostat having both automatic heat-cool changeover and optimum start is disclosed. Programs for the optimum start and automatic changeover are incorporated in a microcomputer based clock thermostat and eliminate any possibility that a homeowner can inadvertently program a sequence that would cause a conflict between the heating and cooling equipment.
