Taco Zone Valves

in THE MAIN WALL
When you place a Taco 3 wire zone valve in the manual position I know that the valve opens and allows water to flow. Does it also close the contact that energizes the circulator/burner relay?

Thanks,
Kenny

    yes

    but it is not a dry contact, of course.

    FYI, On the Taco zone valves, the newer gold heads will bring on the boiler or circ. The older green or gold heads will not.

    The Taco Gold series zonevalves have the manual by-pass to allow water to thermo siphon through the loop for heat in the event you should have a power failure. That is what it was designed for. Some people will try to by-pass when the thermostat is still connected which is not recommended. Doing so can be a detriment to the valve, so Taco advocates removing the thermostat wire off terminal one. Additionally using the manual lever does not guaranty closure of the end switch.
