• Delta-T - variable speed, maintains constant ΔT, provides exact gpm flow required Constant speed - four fixed speeds, maintains constant flow for zoning Set point heat variable speed with boiler protection option, decreases speed on temperature rise Set point cool variable speed, increases speed on temperature rise Boiler protection - protects boiler from low return temperature and flue gas condensation Operating mode, speed or temperature setting, watts, gpm, supply temperature, return temperature and error code diagnostics Use with a Taco ZVC zone valve control or SR switching relay for ON/OFF operation Integral flow check (IFC) is included in carton, simply press into discharge flange if required Nut capture feature on flanges for easier fit up Whisper quiet operation BIO Barrier® protects the pump from system contaminants SureStart® automatic unblocking mode

The VT2218 ECM high-efficiency circulator comes with two temperature sensors to provide Delta-T readings to the pumps brain. So its ready to slash fuel bills right out of the box. The VT2218 ECM high-efficiency circulator is whisper quiet and has a big, bright LCD screen that's easy on the eyes. Simple push-button navigation lets you set the pump to any one of five modes quickly and easily. But what you can't see is just as important, our innovative Bio Barrier® protects the rotor and bearings from system contaminants. Delta-T is the comfort standard for American homes. With our infinitely variable speed ECM motor, the VT2218 ECM high-efficiency circulator uses up to 85% less electricity and maximizes total system and boiler performance. The bottom line more comfort for a lot less money. The VT2218 ECM high-efficiency circulator can slash fuel bills by hundreds of dollars. Its companion, the Zone Sentry® zone valve, draws up to 93% less energy, uses fewer components and can handle up to 12 valves per standard 40 VA transformer. When it comes to zone valves, the Zone Sentry® is the smartest decision you can make.
