Differential thermostatic controller for solar heating system
Patent
·
OSTI ID:6399344
A controller for a solar heating system includes a differential thermostat which responds to a preselected temperature differential between fluid in a solar collector and in a storage tank to operate a motor to pump fluid therebetween. The particular circuitry of the thermostat allows the use of non-linear sensing devices. Safety features includable in the controller provide for sensing of high and low extreme temperature conditions to prevent excess pressure in the storage tank or freezing of water in the collector.
