
The TCH 2xx fuel oil automatic
combustion control unit controls and
monitors the forced draught burner. The
microprocessor-controlled program
sequence ensures maximum stability of
time periods, regardless of fluctuations
in the power supply voltage or the
ambient temperature. The automatic
combustion control unit is designed to
cope with brownouts. Whenever the
supply voltage drops below its rated
minimum level (< 185V), the control unit
shuts down - even in the absence of a
malfunction signal. The control unit
switches itself back on again once the
voltage has returned to normal levels
(> 195V).
