ABSTRACT:
The disclosed temperature monitoring and alarm circuit includes a temperature responsive switch which opens when water temperature exceeds a predetermined point. When the switch opens, a relay is de-energized, thereby activating a latch which activates a visual alarm and closes off a solenoid operated valve on the monitored water source until the over temperature condition is corrected and the circuit is reset.
