What position should zone valve be in?
Otherwise, this wiring is in series with the valve on/off signal. The zone valve needs to be positioned after the boiler and circulator of the central heating system. They can be located either on the hot side (before the hot water goes into the zone) or on the cold side (after the water goes throughout the building).
How do you turn on the Taco zone valve?
Turn t-stat up. Check for 24 VAC across terminals 1&2. If there is power there, wait a few minutes. Feel the manual open lever on the head. The resistance to you moving it should decrease as the valve opens, until the lever goes up and down easily, when valve is fully open. At this point you should begin to get circulation of hot water.
What can zone Sentry zone valves be used for?
(See Geo-Sentry for open system application.) The valves can be used in a wide variety of heating and condensing cooling applications, primarily designed for use with baseboard, fan coils, radiators, convectors, air handlers, heat pumps and radiant applications. Support is only a click away!

Why does my Taco zone head get hot?
If not then problem is external (not the zone valve) If you have 24 volts the head should smell like it is burning, and it should get hot. If you have 24 volts and the head is hot and nothing happens then jump out 2 and 3 if the equipment comes on the the end switch is not making in the head and you need a new head.

What to do if a taco valve fails?
Additionally, if you have valves and a valve fails ( not a Taco valve of course) you can use the bypass lever standard on 570 series valve to induce flow through that zone. If a circulator fails, you can still heat the home with the other circulators. Conclusion: valves, or circulators? It’s your personal discretion. That’s a nice presentation…
Is it better to use zone valves or circs?
Zone valves wherever possible. Makes a more compact and neater install, reliability is a red herring I’ve changed many circs as well as zone valves. Primarily it’s personal preference,whatever you are most comfortable with. My Mom has 3 zones with zone valves installed in 1988 and still going strong.
