Features:
Combustion control according to EN 298 Strong exhaust burner according to EN 676 Undervoltage detection Monitor air pressure during startup and operation with an air pressure switch Convenient remote reset Various colors display information on error status and operating status A limited number of repetitions Precise control sequence due to the use of digital signal processing After 24 hours of continuous operation, it must be stopped once

Electrical connection of flame detectors:
It is important to achieve practically disturbance- and loss-free signal transmission:
1.Never run the detector cable together with other cables
- Line capacitance reduces the magnitude of the flame signal
- Use a separate cable
2.
Observe the permissible lengths of the flame detector cables (see Data Sheets
N7714 (QRB...) and N7716 (QRC...))
3.Earth the burner in compliance with the relevant regulations; earthing the boiler
alone does not sufficeent.
Installation Precautions:
1.The controller unit and other cables must be installed separately from the high voltage ignition cables.
2.Do not confuse phase and neutral.
Install switches, fuses, grounding, etc. in accordance with local regulations.
3.Connection diagram showing the application of a grounded neutral wire to the burner control. Ionization current monitoring in the network without connection In the case of a ground conductor, terminal 2 must be routed through an RC unit (Type: ARC 4 668 9066 0). Connect the ground wire. Local regulations must be followed (e.g. protection against electric shock) Because the mains voltage of AC 230 V / 50 4.Hz produces a current leakage of up to 2.7 mA.
Verify that the maximum amount of current allowed by the terminal is not exceeded.
5.Do not supply an external mains voltage to the control output of the combustion controller, when the test unit controls the combustion controller (fuel valve, etc.), LME do not connect.
In the absence of a fan, the AGK25 must be connected to terminal 3, otherwise the burner will not start reliably.
6.For safety, connect the neutral conductor to terminal 2. As shown below, the burner components (fan, ignition compressor, air valve) must be connected to the neutral conductor. The connection between the neutral conductor and terminal 2 is at the control unit The bottom is pre-wired.
