Manual locking and unlocking
Using the reset button , the control
and safety unit can be locked manually
(interlocked) or unlocked, provided the
unit is connected to the mains power
supply. This function must not be
confused with automatic locking and
fault acknowledgement in case of an
error.
Before installing or removing the unit or
any operation in the connection area,
switch off the supply to the device, check
for the absence of voltage and prevent
any reactivation. Otherwise there is a
risk of electric shock. The control and
safety unit must not be
opened or repaired.
The control and safety unit BT 3xx
controls and monitors the forced draught
gas burner. The microprocessor-
controlled program sequence ensures
the maximum consistency of the cycle
times involved, regardless of
fluctuations in the mains voltage or
ambient temperature. The control and
safety unit is designed to detect power
failures. Depending on the parameter
assignment, the unit either switches to
malfunction mode or goes into the
standby position if the power supply falls
below the mains voltage. In the standby
position, there is an automatic restart as
soon as the set threshold value is
exceeded by 105%.
