The FuelMizer is a combination single zone pump switching relay and outdoor reset control. Improving the efficiency of your hydronic system is as easy as installing the included sensors and wiring the FuelMizer to your boiler. When installed, the SR501-OR-4 will use outdoor temperature information to scale the output of your boiler to match the heat loss of your home. Warm weather shutdown and a selectable boiler minimum protect your boiler from unnecessary wear and tear and condensation, respectively. With a Taco FuelMizer, inefficient comfort and short cycling equipment are things of the past.
Easy-to-interpret external diagnostic lights and "ice cube" style replaceable relays mean that servicing a Taco switching relay is always easy.
The FuelMizer will allow domestic hot water demands to override the outdoor reset control and warm weather shutdown functions.
Zone or System Efficiency
If you just want a single zone of outdoor reset controlled heating, that's no problem. The FuelMizer is compatible with either a zone valve circulator or a system circulator.
