NOTE: All water heating units are shipped from the factory with a resistor (jumper) between
the outdoor sensor terminals (terminals 1 and 2 on TB7). If this resistor is removed,
the water heater will not be able to heat water above 140°F.

7.B.2 Variable Speed Pump Control
Variable speed pump control (V.S.P.C.) is optional
equipment for all commercial Brute boilers and is used to
maintain a user-chosen temperature rise between the inlet
and outlet of the unit.
V.S.P.C. will operate the boiler pump at maximum ow
during boiler startup to ensure stable operation is reached
before introducing variable water ow. This key feature
keeps the boiler’s combustion and variable speed
pump’s ow in phase with each other, protecting the heat
exchanger from potential low ow conditions.
Contact your manufacturer’s representative for more
details.
