Description
The Reznor 260863 Selectra Amplifier is an electronic modulation control module built to regulate gas valve operation for proper burner output in compatible heating equipment. It amplifies and processes control signals between the temperature controller and the modulating gas valve allowing the burner to automatically adjust its firing rate in response to changing heating demands. Mounted in gas-fired unit heaters, duct furnaces, and HVAC systems, the amplifier integrates with the combustion control circuit to maintain stable discharge air temperatures, enhance fuel efficiency, enable fluid control and maintain accurate thermal efficiency.
