    to Taco company....

    Asides from the other tread regarding the Taco zone valves and the transformer(s) wiring hookup... I often wondered why doesn't Taco make a powerhead with dry contact end switch that'll fits to the same valve body as the 571 unit... That way, we have a choice of using ethier model instead of using differnt brands...

    Zone valve heads

    Great idea. I wonder if any one from Taco moniters The Wall? If so they were silent on the great transformer controversy?

    monitor the wall

    John,
    I monitor the wall, as does Joe Mattiello. The product engineering group at Taco is, or will be, responding. I have already discussed with them.
    Give it just a bit of time. Best regards,
    jw

    For years we have used two transformers with out any problems, in fact I think Taco even made it easy, if you buy/use thier 24v transformers they color code one side so hook up is right.

    I couldn't agree more however someone was adamant it couldn't be done that is the "controvesy" I was refering to.

    I have been monitoring the Wall, and seen the thread about the transformers in parallel. Taco has been paralleling transformers on the ZVC406 for years. The 40va transformers put out approximately 3.2 amps collectively which is well below the maximum amp rating for 18 gauge wiring. I visit the wall almost daily but use discretion which threads I jump in to. I provided my contact information if anyone has additional questions.

    The Taco 570 series 3 terminal zone valve has been around since 1969, and has an isolated end switch. Terminal 2 is a two fold terminal. The motor of the 571 is a heat motor. When the thermostat calls for heat, we energize an electric heater that is wrapped around a wax filled chamber through terminals 1, and 2. After approximately 1.5 minutes the end switch closes across terminals 2, and 3 emulating the thermostat to energize the boiler. The valve can be wired along with 4 terminal zonevalves with no problems. The suggestion for converting the 3 terminal to a 4 terminal has been forwarded to the product engineer for review. Thank you

    Thanks for the reply to this post.... Taco can keep the three termimals zone valve and make the new 4 terminals power head on the same valve body... Giving us the choices.... Alongs with better wiring dia.
    Thanks again!
