Honeywell's AquaReset takes an already-efficient Honeywell Electronic Aquastat and uses reliable EnviraCOM communications, already built into most Honeywell combustion products, to link it to an outdoor temperature sensor to maximize energy savings. The boiler setpoint decreases automatically based on the outdoor temperature while still providing all the necessary heat to maintain the comfort level.
