Zone Controls
Taco
Switching Relays combine clearly labeled PC board layouts with advanced
features that allow for total system customization. Whether using basic
priority switching, plug-in PowerPort cards of add-on power controls, the job is
made easy. External indicator lights provide instant diagnostic
feedback, making a snap of service calls or new installation start-ups. A
green light indicates power is connected. When the thermostat calls for
heat, both the appropriate circulator and red indicating light is energized.
All switching relays are UL listed, use standard "ice cube"
replaceable relays and are compatible with conventional and programmable
thermostats. For those larger jobs, the switching relays can be expanded
up to 20 zones with priority. Taco Switching Relays are available in one,
two, three, four and six zones.
Taco Zone Valve Controls work with two-, three- or four-wire zone valves. Fully fuse protected, it also includes and isolated end switch and built in priority switch. The contractor friendly PC board layout eliminates the problems caused by incorrect wiring and the "unfinished" look of conventional zone valve installations. The sturdy screw connections add additional reliability, while the external indicator lights provide instant diagnostic feedback, reducing installation time. All Taco Zone Valve Controls are UL listed and available in three, four, five and six zones. The indicator lights show full functionality of the products wired to the Zone Valve Control. The green light indicates power is connected. When the thermostat calls for heat, both the appropriate zone valve and yellow indicating light is energized. When the zone valve is fully open, the end switch relay and red indicating light are energized.
PowerPort Cards
The PC700 series of Power Controls can be used in conjunction with any Taco expandable relay unit (-EXP model). There are no complex wiring diagrams, simply plug the interface cable directly into the expandable relay and then attach the supplied sensor; That’s it. By controlling the supply water temperature based on the outdoor temperature, the heat lost from the building is matched by the heat input to the building. Firing cycles of the boiler are also optimized to increase comfort and provide energy savings. The ease-of-installation combined with full diagnostic capabilities makes it simple to upgrade any system. Taco Power Controls can be used in parallel with the PC600 series of Power Port Cards to further enhance total system operation.
The PC600 series of PowerPort Cards can be used in conjunction with any Taco expandable relay unit. Each Taco expandable relay (-EXP model) comes standard with three PowerPort slots to accept any combination of cards. By controlling the operation of the circulators attached to the switching relay, the PC600 cards are an ideal way to provide energy savings, system protection and an increased comfort level. With no additional wiring, the PC600 cards can also be used in parallel with the Taco Add-on Power Controls to add even greater system control and boiler optimization. Mix and match the cards and controls to upgrade any system.
Zone Pumps
The Taco Priority Zoning Circulator combines the reliability of the "00" Circulator with the convenience and efficiency of a PC board mounted switching relay package. Each Zoning Circulator has low and high voltage terminal strips for ease of electrical hookup as well as built-in priority switch. The priority switch allows the installer to choose the zone that requires the most attention, and when activated, only that Circulator can be used in conjunction with other Circulators of Zone Valves. Ideally used for indirect hot water heaters, adding another zone, zoning with Circulators and for prioritizing under-sized zones. Available in a full range of sizes from 003 through 0014 to match your specific system requirements.
I Series Valves
Taco iSeries Mixing Valves provide
precise and cost-effective temperature control for your heating
systems, the flexibility of zone-to-zone control, plus built-in
boiler protection.

Available
in 2-way, 3-way or 4-way injection configurations 
Ever since
reliable electric zone valves were developed many years ago, they have been by
far the most widely used device for zoning a system. They eliminate the need for
a Flo-Chek valve and relays, and simplify the piping. Their compactness
permits great flexibility of location in the system. This and the silent
operation of the Taco valves having heat motor type operators permits
installation in or near rooms where noiseless operation is desired, such as
bedrooms. A single circulator in the system can supply from two to many
zone valves. 
A Taco Electric Thermostat is used to sense the temperature in each zone and control operation of the zone valve for the zone. The valve may be located within the zoned space or at any convenient location in the pipe loop for the zone. In a series loop system, usually the valves are placed at the discharge side of the boiler. In a two-pipe system, the valves are placed at the radiation unit supply or return.
The 5000 Series Mixing Valve is a dual purpose mixing or diverting valve. It is ASSE 1017 approved, providing shut-off reliability on either a hot or cold water supply failure. The high flow and low head loss characteristics make the 5000 Series ideal for domestic water, radiant applications, installations with large variations in flow rate and supply conditions, and installations requiring tightly controlled water temperature. The valve’s unique design and advanced thermostatic element ensures a stable mixed water temperature throughout the extended 85° - 150° F range. The 5000 Series provides fail-safe security and ultimate performance in a mixing valve.
Feed Valves
Taco Pressure Reducing Valves are used to automatically feed water to a hot water heating system whenever pressure in the system drops below the pressure setting in the valve. They feature fast fill rates, an exclusive fast fill lever lock, built-in check to prevent emptying the system if incoming pressure fails, union connections with tailpiece standard and the pressure setting adjustment separated from the fast fill lever for easy, fast adjustment. Available for systems in a pressure range from 10 to 25 PSI.
Geothermal Valves
Created especially to eliminate noisy water hammer. The Taco GT Whisper Guard operates in a totally different way from fast-acting solenoids. How? It closes slowly and no water hammer occurs. The unique end-switch design permits control of the heat pump by the valve. This allows movement of cold water into the coil before the heat pump actually starts. The bronze body and corrosion resistant internal parts provide for long, trouble-free service. The Taco GT Whisper Guard is available with 3/4” thread (5101-G2), 1” thread (557-G2), or 3/4” sweat (556-G2).
Thermostats/Transformers
The Taco thermostat has an adjustable heat anticipator and temperature range
from 50° F to 90° F, and requires a 24 Volt, two-wire circuit
The Taco transformer reduces line voltage to low voltage when used in
conjunction with Taco Zone Valves.
Venturi Fittings
Taco Venturi fittings are designed to divert water flow from a given zone to the by-pass loop. The flow from the zone is partially diverted through the by-pass and then returned back into the zone. The Venturi Fitting creates a differential pressure that make some of the flow want to divert through the by-pass and back to the zone. The Taco Venturi Fitting can be used in up-feed or down-feed applications. The typical application for the Taco Venturi Fitting is to divert heated water through kickspace heaters, convectors, radiators, or base board. The Venturi is ideal for retro-fit applications where more radiation needs to be added to a existing job.
Flo-Checks
Taco Flo-Cheks have dependably stopped gravity circulation in forced hot water heating systems for over 40 years. Flo-Cheks open automatically when the circulator starts running. They feature a thumb screw to manually open the valve, and are available in a cast iron universal body and a bronze sweat in-line configuration. A unique, re-designed weighted check on the 221 and 222 models features an enhanced seating and quieter operation on high flow systems.
