Taco Geothermal Valve Wiring

A wiring diagram is a simplified standard photographic representation of an electrical circuit.

Taco geothermal valve wiring.

Taco 5101 g3 5101 g3 3 4 threaded geothermal valve taco geothermal valves are designed for high head open system zone control. All this adds up to a geothermal zone valve that leads the industry in energy efficiency flow capacity cv. Hydronic heating the best way to test a series 570. It shows the parts of the circuit as simplified forms as well as the power and also signal links between the tools.

Geothermal heat motor zone valves models 5101g 556g 557g taco geothermal heat motor zone valves are designed for high head open system zone control. 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. 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.

3 wire taco zone valve. Variety of taco 3 wire zone valve wiring diagram. The taco geo sentry geothermal zone valve enhances the overall performance of any geothermal system. Instead it is pronounced take oh.

I noticed my well pump was coming on and loosing pressure immediately even when the units weren t running. The explanation below and associated diagrams explain step by step the operation of the zone valve. 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. I had two geothermal units installed in my home seven years ago.

Since then i ve had to replace the taco zone valves twice on one unit and three times on the other. 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. As the air temperature at the thermostat drops to the thermostat. This older style water valve had the orange cover over the actuator.

For proper operation and performance. 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. Wiring geothermal water valves of this older design is slightly different from the wiring of the newer green taco valves.
