The ESP energy storage principal motorized zonevalve has been reintroduced as the EBV electronic ball valve. The name change is synonymous with engineering changes that have made this one of the best motorized zone valves in the industry. For your reference I have attached the catalog, submittal data, wiring diagram, and instruction sheet. Please visit www.taco-hvac.com for additional information on products to help facilitate wiring.
The SBV Synchronous ball valve is an OEM proprietary product, and not available for general sales.

Joe Mattiello The same wiring

is shown for converting from White Rodgers SPDT power to open power to close system as was shown with ESP wiring. Your diagram shows wires 4, 5 and 6 from the existing thermostat being wired to 4 and 6 with the "ESP" and also now with the EBV. I had brought this to Mark Chafees attention quite a while back.

If you look at the internal wiring of the thermostat the anticipator is wired between terminals 5 and 6. By wiring to 4 and 6 there is now no anticipator for the thermostat. The fact is when replacing a SPDT (series 20) control with a two wire (series 80) control the thermostat must be replaced.

Supply

Joe,

Are there supply issue with the zones? I seam to have exhausted the supply for my area. Now I am scrambling to keep my crew working, Any ideas ? We like the Taco because of the amount of work involved in determining the direction of flow, It is a large Apt. bld.

Joe one ? if i may...

i just read the temp ranges 20 degree to 240F and a small disclaimer on not intended for condensing applications. would you mind elaborating on that a bit? i am fairly certain that i have seen them used on snow and ice melt set ups where the fluid if not idling at 37 must be significantly cooler.....
