Taco Inc. offers an all-in-one pump/control variable voltage version of its Variable Speed 00 circulator for a wide range of commercial building HVAC applications. It has been designed to operate the pump at different speeds based on an externally generated analog voltage signal input. The 00-VV’s control accepts four external signal voltage ranges: 0-10 V(dc), 0-20mA, 2-10 V(dc) or 4-20mA signal. The 00-VV also features a manual operation switch to validate the pump’s operation and internal LEDs. It can be used either linear for standard applications or for logarithmic outputs for use with fan coils.
