ABSTRACT OF THE DISCLOSURE A control device is provided for controlling the temperature sensed by a thermostat in specific relation to the temperature control setting of the thermostat for thereby controlling work cycles of the system operatively connected to the thermostat. A low resistance heater element is mounted in a vented housing through which a convection current is generated when the heater element is actuated. A damper is movably mounted in the housing for adjusting the convection flow of warm air that outlets through the housing. The housing is mounted a predetermined distance from the sensor element of the thermostat and the thermostat is preset to a desired temperature setting. When the heater element in the device is not actuated, the device has no control over the operation of the thermostat. When the heater element is actuated, the extent of control of the device on the operation of the thermostat is regulable by adjusting the damper to control the output of warm air to the thermostat sensor. According to one mode of opera- tion of the device, the heater element may be operatively connected to a power supply cord of the type having a plug which is releasably connectable into an electrical outlet, for instance of the type conductively connected to a residential electrical system. According to another mode of operation of the device, the heater element may be operatively connected to a conventional commercially available timer of the type commonly employed in a household to automatically energize a light or appliance through a desired interval. -1-
