Kromschroeder 84367170 IFS110IM-5/1/1N automatic gas firing device operation

Upon thermostat activation, the control system checks for flame simulation and failsafe within the testing time. If no flame signal is detected, the burner starts with voltage applied to valve 1 and the ignition transformer. If flame simulation is detected, the testing time extends up to 10 seconds before entering lockout. Following burner start, a flame signal must be detected within the safety timeframe, triggering valve V2 opening. If no flame is detected, a fault-lockout occurs. Continuous flame signal monitoring occurs during burner operation, also after shutdown. If the flame persists after shutdown, a fault-lockout is initiated, indicating both internally and externally. The IFS 111 IM model applies voltage to external fault indication only upon thermostat activation. Resetting from fault-lockout is possible via internal or external push-button.
