Kromschroeder 84367010 IFS110IM-3/1/1T automatic gas firing device operation

After the thermostat has called for heat, the control checks for flame simulation and failsafe during the testing time tp. If a flame signal is not detected during the testing time, the burner is started: Voltage is applied to valve 1 and ignition transformer. The testing time increases up to 10 sec if flame simulation is detected. The control then goes to lockout. Following the burner start, a flame signal must be measured within the safety time: in this case, after the period voltage is applied to valve V2, which then opens. If a flame does not establish, the control goes to fault-lockout. During the burner operation, the control continuously checks for a flame signal. The burner control unit also checks for a flame signal after the burner has shutdown. If the flame does not extinguish within approx. 10 sec after the burner has been shutdown by the thermostat, the control will go to fault-lockout. The fault-lockout is connected with an internal and external fault indication. With IFS 111 IM, voltage is applied on the external fault indication only, if the thermostat calls for heat. Reset following a fault-lockout by means of an internal or external push-button.
