What it is

This is a Satronic (Honeywell/Resideo) MMI 810.1 mod 40-34 gas burner safety control box, part number 0620820U, rated at 240V. It manages the burner's light-up and shut-down sequence, including pre-purge, ignition and ignition safety time, and monitors the pilot and main flame stages.

  • No pre-purge or ignition cycle when a call for heat is received
  • Flame is detected but the control box does not respond correctly
  • Control box fails to power up

Before you order

  • Have the work carried out by a Gas Safe registered engineer
