The TCG 1xx automatic gas combustion
control unit controls and monitors the
forceddraught burner.
The microprocessorcontrolled programme
sequence ensures maximum stability of time
periods, regardless of fluctuations in the
power supply or ambient temperature. The
automatic combustion control unit is
designed to cope with brownouts,
guaranteeing system operation even in the
event of extreme power failures. Whenever
the supply voltage drops below its rated
minimum level, 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.
Locking and unlocking the system
The control unit can be locked (switched to
malfunction) and unlocked (malfunction
cleared) by pressing the R reset button,
provided the system is connected to the
mains power supply.
Always disconnect the power supply
before installing or removing the
control unit. Do not attempt to open or
carry out repairs on the control unit.
