| Technical specification | 23221644 Weishaupt Low-NOx, sliding-two-stage, W-series gas burner, model WG20N/1‑C ZM‑LN. Modulating load control of the burner can be achieved via three-term switching from a suitable PID controller (separate supply). Alternatively, modulation control can be achieved either via an external Modbus-RTU or Profibus-DP signal, if the burner is equipped with the optional EM 3/2 field bus expansion module, or via an external 0 10 V or 4 20 mA signal if the burner is equipped with the optional EM 3/3 analogue expansion module. Burner construction includes Weishaupt motor, flame sensor, ignition equipment, and digital combustion manager. Monitoring and control of all important burner functions and the electronic compound regulation of fuel and air is effected by the integrated digital combustion manager. Setting and control of the burner is achieved using the burner-mounted digital control and display unit. Burner complete with: • 1" gas multifunction assembly, incorporating • Solenoid valves • Low-gas and valve-proving pressure switch • Governor • Filter • 2 double nipples • 90° elbow • Gas ball valve Minimum gas flow pressure: 17 mbar* Maximum gas flow pressure: 25 mbar *Pressure required at the inlet to the gas valve train with all upstream consumers running at maximum load.
