Operation
TCH 24x control unit
The TCH 24x fuel oil automatic
combustion 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 control and
safety unit is equipped with a device to
protect against the effects of 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).

Locking and unlocking
The control unit can be locked using the

or unlocked as long as
the unit is powered on.
Always switch off the power supply
before installing or removing the
control unit. Do not attempt to
open or carry out repairs on the
control unit.
