MADE IN USA

Application: Radiant Floor

The VT2218 is a temperature sensing, variable speed circulator ideal for Delta-T or setpoint temperature applications. Typical uses include hydronic systems zoned with zone valves, radiant loops, injection pumping, snowmelt or hydro-air fan coils. Can also be used in constant speed mode for zoning with circulators, indirect water heaters or primary boiler loops.

The VT2218 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.

The Viridian VT2218 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.

Specifications:

  • High-efficiency ECM motor uses up to 85% less electricity

  • Infinitely variable speed settings to fine tune flow for any system

  • Sure Start automatic unblocking and air purging mode

  • Integral Flow Check (IFC) is included in carton.

5 Operating Modes:

  • Delta T
  • Constant Speed
  • Set Point Heat
  • Set Point Cool
  • Boiler Protection

Delta-T : Variable speed, maintains constant ∆T, provides exact GPM flow required

Constant Speed: 4 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 • Illuminated LCD displays: - Operating mode, speed or temperature setting, watts, gpm, supply temperature, return temperature, and error code diagnostics.
