Taco Geothermal Valve Wiring

The brand taco is not pronounced like the mexican food item taco.

Taco geothermal valve wiring.

The unique end switch design permits control of the heat pump by the valve allowing cold water into the coil before the heat pump starts. The valves can be used in a wide variety of heating and non condensing cooling applications primarily designed for use with baseboard fan coils radiators convectors air handlers. Wire diagram for taco zone valves taco zone sentry zone valves provide on off normally open or normally closed control in both open and closed hydronic systems. The taco geo sentry geothermal zone valve enhances the overall performance of any geothermal system.

The older taco model 5101g water valve is shown. I had two geothermal units installed in my home seven years ago.

Geothermal heat motor zone valves models 5101g 556g 557g taco geothermal heat motor zone valves are designed for high head open system zone control. Wiring geothermal water valves of this older design is slightly different from the wiring of the newer green taco valves. For proper operation and performance. The unique end switch design permits control of the heat pump by the valve allowing cold water into the coil before the heat pump starts.

Since then i ve had to replace the taco zone valves twice on one unit and three times on the other. The explanation below and associated diagrams explain step by step the operation of the zone valve. A wiring diagram is a simplified standard photographic representation of an electrical circuit. It shows the parts of the circuit as simplified forms as well as the power and also signal links between the tools.

Heat motor zone valves zone valve operation and wiring there have always been questions surrounding how the 3 wire terminal block design of the taco heat motor zone valve works. Hydronic heating the best way to test a series 570. This older style water valve had the orange cover over the actuator. As the air temperature at the thermostat drops to the thermostat.

The unique patented technology in the geo sentry utilizes a microcircuit based logic to control a gear driven electronic actuator which drives a ball valve based body design. Instead it is pronounced take oh. All this adds up to a geothermal zone valve that leads the industry in energy efficiency flow capacity cv.
