Taco’s FuelMizer outdoor reset switching relay is a microprocessor-based control designed to regulate the supply water temperature of a single boiler, based on the outdoor temperature. FuelMizer is ideal for retrofits but may also be used for new installations. It is capable of controlling a system or zone valve circulator, as well as overriding outdoor resets when a DHW tank calls for heat. Contractor friendly with logical layouts and intuitive, customized controls, the FuelMizer will not affect the boiler’s warranty.www.taco-hvac.com/fuelmizer
