Maxitrol A1044R Amplifier R-410A While both use a 48-inchThe Maxitrol A1044R Amplifier is the direct engineering successor for the obsolete A1044, A1044U, A1044D, and A1044E models. As the core control logic for Selectra Series 44R systems, this amplifier provides high precision gas flame modulation for direct fired space heating applications. It is designed to interface seamlessly with M411, M511, M611, and MR212 series modulator regulator valves, ensuring stable discharge air temperatures across all
