Automatic temperature control
An automatic temperature control system is described for maintaining a preset temperature in an enclosed space in a building, comprising: heating and cooling means for conditioning the air in the enclosed space to maintain the preset temperature; exterior thermostat means outside the building for sensing ambient exterior temperature levels; interior thermostat means in the enclosed space, preset to the preset temperature to be maintained and connected with the heating and cooling means to energize the means for heating or cooling, as appropriate, when the preset temperature is reached; means defining a heat sink containing a volume of air heated by solar radiation, the volume of the heat sink being such that the temperature level therein is not affected by minor or temporary ambient temperature fluctuations; and heat sink thermostat means in the heat sink sensing the temperature in the heat sink, the heat sink thermostat means being connected in tandem with the exterior thermostat means and operative with the exterior thermostat means to switch the interior thermostat means to either a first readiness state for heating or a second readiness state for cooling, depending upon which mode is indicated by both the exterior and heat sink thermostat means, whereby the system automatically switches between heating and cooling, as required, in response to a comparison of exterior and heat sink temperatures.
