The device operates in intermittent (cyclic) mode and is suitable for burners with forced air supply (with fan) and without it. The control unit is widely used in various heat generating equipment: gas, liquid fuel and combined boilers (domestic and industrial); air heaters, hot air generators; air heaters, infrared heaters; water heaters, process furnaces, drying chambers; burners Riello, Baltur, Weishaupt, Lamborghini and other brands. Important information about time parameters: The DMN31 model is available in several modifications that differ in pre-purge time (tv/tp), safety time (ts) and waiting time (tw). For part number 37546070, these parameters are preset by the manufacturer. Before purchasing, be sure to check the marking on the housing of your old unit with the characteristics of the new one. Typical combinations for DMN31: tv/tp = 10 s, ts = 5 s, tw = 10 s (e.g., art. 37546050); tv/tp = 30 s, ts = 5 s, tw = 30 s (e.g., art. 37546060); other options are possible (e.g., 5/3/5 s). For part number 37546070, check the current values with the seller or by the marking on the housing. Mismatch of parameters will lead to incorrect operation or safety lockouts.
