The Innovative Controls Inc. 3050803 Pump Overheat System
monitors pump water temperature and at 125o
F(52o
C) or above
can automatically activate an audible alarm and/or a thermal
relief valve option that releases water from the pump to the
ground or back to the water tank. The optional thermal relief
valve automatically closes when the water temperature cools.
A status LED tells the operator when the system is dormant
(under temp) or active (over temp), and the system can be tested
at any time by pressing a Push to Test button.
