Maxitrol A1014R Amplifier

The Maxitrol A1014R Amplifier is a high-performance electronic gas flame modulation control designed for Selectra Series 14 systems. Engineered to provide precise temperature regulation in direct-fired make-up air applications, this unit functions as a direct replacement for the Maxitrol A1014, as well as the A1014L, A1014L1, and A1014U models. By outputting a variable DC voltage to M or MR modulator valves, it ensures instantaneous response to thermal fluctuations. The A1014R universal amplifier features an integrated 40-80°F temperature dial and a sensitivity adjustment knob, allowing technicians to fine-tune system stability and eliminate hunting. It includes a selectable low-fire start (LFS) dipswitch, providing a 0 to 10-second delay to ensure smooth ignition before reaching full modulation. This Selectra Series 14 amplifier is compatible with natural, manufactured, and LP gases, making it a versatile choice for commercial HVACR industrial heating retrofits and new equipment installations.

• Universal Compatibility: Serves as the designated A1014 replacement and is compatible with M411, M511, M611, and MR212 series valves.
• Enhanced Control: Features an integral discharge temperature dial and TDS dipswitch for seamless switching between local and remote temperature selection.
• Advanced Diagnostics: Includes a built-in power indicator LED to simplify field troubleshooting and verify 24V AC input status.
• Operational Range: Optimized for all standard temperature ranges, maintaining stable performance in ambient conditions from -40°F to 125°F.
• Flexible Installation: Supports lead lengths up to 200 feet when using separate conduit for control wiring, ensuring signal integrity in large-scale facilities.

Is the A1014R a drop-in replacement for the older A1014 models?
Yes, the Maxitrol A1014R is the direct universal successor for the A1014, AD1014, and all 'L' or 'U' suffix variants, incorporating modern circuitry while maintaining the same terminal footprints.

Can I use a grounded transformer with this amplifier?
No. For proper flame modulation control, the 24V AC transformer secondary must remain floating. If your current system uses a grounded transformer, you must install an isolated transformer to prevent electrical interference or damage to the circuit.

How do I adjust the system sensitivity?
Use the sensitivity adjustment knob located on the face of the amplifier. Rotate clockwise to increase the speed of the valve response if the discharge air is too cool, or counter-clockwise if the system is oscillating (short-cycling) around the setpoint.
