Taco 561-5 - 3/4" Sweat 3-Way Zone Valve- 560 Series Heat Motor Zone Valves offer a 3-way bypass version of the Taco 570 Gold Series. Use valves in this series to control the flow to a fan coil or terminal heating unit. I can give you a general idea but as for what the valve controls is up to the install. On a basic Honeywell zone valve there are four leads two yellow and two red. The red are an end switch that makes when the valve is fully open, so if you check them with a continuity tester they will only be made when the valve is driven fully open. Download this manual.

And I have no idea how to wire it up. I watched a video that showed me how to wire the valve controller. By wiring the circulator to the pump end switch and each of the thermostats to the proper zone and each zone valve to the proper zone on the board.The Taco Potable Water Zone Sentry zone valve is availableLeakBreaker ® is a water heater leak protection devic So, it bypasses the switch that sends full power to open the valve and gets what it needs, and sends the rest down through the heat coil of that zone valve. This works fine until there is a call for heat and that taco valve opens. When the valve gets near full open, it interrupts current by opening a switch, so the heater coil doesn't overheat. Control Valve: The control valve is part of Taco Zone Valves and Thermostats, the system’s performance and dependability is maximized. ©Taco Catalog #100-5.1 Effective Date: 07/11/07 Supersedes: 04/15/04 Printed in USA ...

July 2023 edited July 2023. I have a 1" pipe line to a sidearm hot water heater and I bought a 1" Taco zone valve (Z100T2-3) to control flow to it. The valve BODY is 1", but internally the diameter reduces to 1/2". The same is true for a 3/4" Taco zone valve (Z075T2-3). I don't want this; I want the full flow rate 1" and 3/4" pipe provides.Since there's a common circulator pump and controls one might naturally suspect either the zone valve itself ( a bad connection, loose wire), or a bad control module in the Taco master zone control. Take a look at the system temperatures and at whether or not you are using domestic hot water when this short-on-zone problem is occurring.Zone Valve Control: Transformer and relay in one box, which allows a low voltage thermostat to control a low voltage zone valve, with an isolated end switch that can energize the boiler and/or circulators.
