unit statistics
The TCG 1xx automatic gas combustion
control unit controls and monitors the forced-
draught burner. The microprocessor-
controlled 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.
