Abstract
The sun sensing control device includes an upright hollow elongated housing having a sealed compartment therein containing fluid. An electrical transducer is mounted at least partially within the compartment. The transducer responds to changes in the characteristics of the fluid within the compartment when solar radiation, impinging on the housing, heats the fluid in the compartment. In response to such changes, the transducer provides an electrical signal indicative of the presence of adequate solar radiation for energizing a solar heating system.
