Lochinvar’s CREST Condensing Boiler with Hellcat Combustion Technology features RealTime O₂ Trim. This combustion technology includes Feed Forward, Feed Back, Commissioned Trim and Learned Trim to allow the user to set tailored parameters, so the unit can run at peak performance around the clock without needing to make manual adjustments. CREST boilers with Hellcat Combustion Technology feature an O₂ sensor exclusively designed for a condensing, hydronic boiler, along with Lochinvar’s SMART TOUCH operating control that adapts to rapidly changing environmental conditions. The new technology accounts for seasonal changes, shifts in weather patterns and altitude. The control platform records the optimal settings and logs that information, and when those same environmental conditions arise, the combustion system automatically adjusts.
