Taco Zone Sentry Zone Valves provide on-off, normally closed control in both open and closed hot or chilled water hydronic systems. The valves can be used in a wide variety of heating and cooling applications, primarily designed for use with baseboad, fan coils, radiators, convectors, air handlers, heat pumps and radiant applications. Savings and efficiency are what the Zone Sentry is all about. Using patented technology and microcircuit-based logic, it draws just 1.44 watts when it"s ON, and is expandable to up to 12 zone valves per standard 40 VA transformer, saving on components. The Taco Zone Sentry is the most technologically advanced zone valve ever made. It"s also simple to install and operate. The valve can be installed in any direction, in any orientation. We then went a step further, allowing the operator to be mounted to the valve body in either direction, great for those tight baseboard jobs. Snap-in quick connects on the back of the valve make for a simple, secure and fast wiring hook-up. A green LED light shows full functionality of the valve"s operation and thermostat sta-tus. Under a no power situation the manual override button located on the top of the valve allows the ball to be rotated up to 90° and is also marked with a slot to indicate the position of the valve.Shop for more Taco e-Smart Products
