An electromechanical thermostat for controlling the on/off cycle of a heating/cooling unit. The thermostat has a temperature sensing element with a variable position according to the sensed temperature. Associated with the sensing element is a switch member that provides on/off signals in response to the position of the sensing element. The thermostat has mechanical heat anticipation to control the generation of the on/off signals. In the preferred embodiment the mechanical heat anticipation is accomplished by a stepper motor which varies the position of either the sensing element or switch member to simulate thermal heat anticipation. The thermostat also has a mechanical structure to reduce or eliminate thermostat droop. Preferably this structure includes a control circuit to detect the duty cycle of the heating/cooling unit and mechanically and automatically adjusts the thermostat set point.
