Lochinvar® Corp. has introduced the versatile MP2™ Sequencer, specifically designed to maximize the performance of Lochinvar's high-efficiency Copper-Fin®, Copper-Fin II® and Efficiency+® boiler lines. A "sequencer" is the automated control system that determines when to fire each boiler, in what order, and for how long. The precision and versatility of the MP2 sequencer ensures the utmost efficiency, consistency, and reliability in a heating system by providing up to nine on/off stages based on outdoor temperature, a set point requirement, or an external input signal. The MP2 sequencer employs indoor/outdoor reset to determine the rate of heat loss in a building and adjusts the heat supply accordingly. This feature increases energy savings by providing heat only when needed, and it improves comfort by eliminating temperature swings. Lochinvar® Corp.
