Description
The Lennox 19J99 Ignition Control is an integrated furnace control that is used to control ignition sequences in HVAC systems. It operates at 24V AC and 60Hz to ensure proper ignition of gas-fired furnaces. This control module is used in Lennox furnaces to enhance the efficiency and reliability of the system. This is achieved through the ability to time the ignition sequence, detect the flame as well and control the fuel burn rate to prevent overheating and therefore reduce unnecessary shutdowns.
