Type: Honeywell 0620220U MMI810.1 Mod. 33 Automatic burner control unit NEW
The MMI automatic burner control unit controls and monitors forced draught and combination burners with any nominal heat load (tested and approved to EN 298). The automatic burner control units MMI 810.1 Mod. 13, 33 and 35 can also be used for burners on stationary hot air heaters
(WLE according to DIN 4794). Different type and model designations differentiate the machines partly in the programme times and
for the different country standards.
