Kromschroder Burner control unit IFS110IM-3/1/1T 84367010

The Kromschroder IFS110IM-3/1/1T is a burner control unit for gas burners in continuous operation. It manages ignition and flame monitoring using an ionization electrode or UV-cell, with continuous flame checking and a fault-lockout on flame failure or simulation. The unit operates at 220–240 V, consumes 5 W, and supports a total load of 2 A. It features a remote reset signal, external fault indication, and a flame extinguish check time of 10 seconds. The housing is impact-resistant plastic, and the device is EC tested and certified, conforming to DIN 4788 and VDE regulations.

When selecting a replacement burner control unit, verify the supply voltage, power consumption, and total load ratings match the existing system. Ensure the flame detection method (ionization electrode or UV-cell) is compatible with the burner's sensor. Check the cable gland size (PG 9) and the number of cable entry holes (7) to match the wiring setup. The unit can be installed in any position, but ambient temperature must be within -20 to 60 °C.

Typical failures of burner control units include lockout due to flame simulation or failure to extinguish, often indicated by a fault lamp or external signal. If the unit fails to detect a flame within the safety time, it will lock out and require a manual reset via the internal or external push-button. Check for loose connections, damaged electrodes, or incorrect wiring that may cause intermittent faults.
