Control And Regulation Unit For Gas Wall Hung Boilers

Designed according to EN-298:2003 standard, in order to perform ignition, flame control, safety management and temperature regulation with a digital PID algorithm. A multi-processor architecture separates regulation and safety parts, having high flexibility during integration between customer specification and Authority validation.

Features

  • CE approval according to EN-298:2003, EN60730-1, EN60335-1 standard.
  • Integrated ignition, flame control, safety management.
  • Flame detection through ionization sensing.
  • Sanitary/heating water temperature regulation through digital PID.
  • Manages volatile/no-volatile lockout, through an EEPROM.
  • Drives external room thermostat.
  • On board SMPS with standby consumption < 0.3W @ 254Vac.
