  • Back-up auto-thermostatic modulating regulator
    Patent number: 6102297
    Abstract: An automatic modulating regulator device and method of operation for use with a non-electrical hot water heat source supplied by a pressurized water supply. The hot water heat source has a hot water circuit to pump hot water to heat exchange elements. The regulator device comprises a valve which when a power failure occurs changes to a normally open state. The regulator device is adapted to be connected to a hot water return conduit of the hot water circuit. A self-powered thermostatic valve is responsive to a temperature sensor and modulates the flow of hot water returned through the regulator device. A flow restrictor is connected downstream of the regulator device for releasing controlled quantities of water from the return hot water conduit to a drain.
