Description：

The TMG 740-3 burner control box is capable of controllingand monitoring medium to high performance forced draughtand dual fuel oil/gas burners in single or two stage versions.It can be used, as prefered, for multi-stage or modulatingoperation with burners of any nominal rating as well as indirect air heaters (as per DIN 4794).Different model designations identify the control boxesaccording to programme times for varying national standards,or forspecialapplicationse.g. high-speed steamgenerators.A special version is available for operation with ignitionspark monitoring in conformance with French nationalregulations.

The TMG 740-3 is fully interchangeable with the earlierversions -1 and -2.

The Honeywell TMG 740-3 Mod. 43-35-110V Burner Control Box is a microprocessor-based burner management controller used for the automatic supervision and safe operation of industrial and commercial combustion systems. The unit controls burner startup sequences, monitors flame presence, manages safety interlocks, and initiates automatic shutdown procedures when unsafe operating conditions are detected.
