Weil-McLain's Advanced Features Module (AFM) brings outdoor reset control to the Ultra Oil hot water boiler. Capable of controlling either an actuated mixing valve or a variable speed injection pump in addition to two Ultra Oil boilers, the AFM also provides seamless temperature mixing for your hydronic system. An option for indirect domestic hot water priority means that your outdoor reset temperature does not have to interfere with DHW production. In addition to improving system efficiency with outdoor reset, the AFM also improves system durability when a pair of Ultra Oil boilers are connected. By staging the boilers and maintaining an equal run time rotation, the AFM prevents short-cycling and reduces wear and tear. The Weil-McLain Ultra Oil is an amazing product out of the box, but adding an Advanced Features Module unlocks its full potential.
Extreme Weather Protection
The Advanced Features Module provides warm weather shutdown and freeze protection to connected Ultra Oil boilers. Warm weather shutdown prevents equipment from firing above a certain outside temperature and freeze protection fires equipment in cold temperatures to prevent burst pipes.
