03/2011 - Art. Nr. 4200 1016 4000C
The TCH 1xx fuel oil control and safety
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 or ambient temperature. The
design of the automatic combustion
control unit protects it from the effects of
brownouts. 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.
8: End of heat request, solenoid
valve closes, burner stop
9: Standby
