Honeywell TF 974 Combustion Control Unit

The TF 974 or TF 976 control units are designed to control diesel burners, which can be equipped with a liquid fuel preheater, with a capacity of up to 30 kg/h. The control units are tested and certified according to EN 230.
A special contact in the burner control unit closes the heater's thermostat as soon as the burner starts operating and a flame signal is received. This prevents the burner from shutting down due to a drop in liquid fuel temperature (for example, in the case of high fuel flow rates).
If the furnace circuit breaker goes into the lockout position, the voltage to the liquid fuel heater also stops flowing.

The automatic furnace control unit is protected by a fire-resistant transparent plastic housing. It includes a thermomechanical timer with temperature compensation, flame monitoring, and a reset circuit.
