Honeywell TF 834.3 Satronic 02234U control unit

Controls and monitors  fan burners with or without oil pre-heaters and with an oil consumption of up to 30kg/h (tested and approved according to DIN 4787).

A special contact in the firing unit bridges the release thermostat of the oil pre-heater as soon as the burner is in operation and a flame signal is given. Thus an interruption of the operating process due to a decreasing oil temperature (e.g. in case of high oil flow) is prevented. In case of a fault shut down, also the oil pre-heater is disconnected from the power supply.
For single-stage oil burners up to 30 kg/h with oil pre-heating
SLV 10, BNR 10 - BNR 22
