INSTRUCTION MANUAL OF THE SIEMENS CLIMATIX 2 CONTROL EQUIPMENT

-
The parameter setting is ranging from 0 – 190°C; the default value is 35°C.
The instructions for changing this parameter can be found in chapter 4.
The Differential B2 B8 reduce parameter determines the maximal difference (in Kelvin) between
the boiler temperature B2 during reduce and the flue gas temperature B8. The setting 25 K means
that the difference between the flue gas temperature during reduce and the boiler temperature can
be 25 K at the maximum, otherwise the error mode “Loss of flame – reduce“ is activated.
The parameter setting is ranging from -30 to 60 K; the default value is 25 K.
The instructions for changing this parameter can be found in chapter 4.
The Error delay number cycles parameter determines how many cycles of feeding during reduce
must pass before the error mode “Loss of flame reduce” is activated. It is determined according
to the difference between the boiler temperature B2 and the flue gas temperature B8 (see the
Differential B2 B8 reduce parameter).
The parameter setting is ranging from 0 – 20 cycles; the default value is 3 cycles.
The instructions for changing this parameter can be found in chapter 4.
The Delay time of ignition after reduce parameter determines how long the temperature
conditions for ignition are ignored after the switchover from reduce to operation and determines the
time which is necessary for the boiler to begin to burn. If this time passes and the conditions for the
boiler operation are not met, the automatic ignition is activated.
This parameter can be found only in the configuration Ignition – YES.
The parameter setting is ranging from 0 - 600 s; the default value is 280 s.
The instructions for changing this parameter can be found in chapter 4.
The Differential B8 B2 operation parameter determines the minimal difference (in Kelvin)
between the flue gas temperature B8 and the boiler temperature B2 in operation. The setting 1
K means that the flue gas temperature B8 in operation must be by 1 K higher than the boiler
temperature, otherwise the error mode “Loss of flame - operation” is activated.
This parameter can be found only in the configuration Ignition – NO.
The parameter setting is ranging from -10 to 30 K; the default value is 1 K.
The instructions for changing this parameter can be found in chapter 4.
The Hysteresis differential B8 B2 operation parameter determines when the acceptable
operation state of the boiler is re-evaluated.
In order to deactivate the error mode “Loss of flame – operation“, the flue gas temperature must be
higher than Differential B8 B2 operation + Hysteresis differential B8 B2 operation.
This parameter can be found only in the configuration Ignition – NO.
The parameter setting is ranging from 1 - 30 K; the default value is 1 K.
The instructions for changing this parameter can be found in chapter 4.
The Delay of loss of flame parameter determines how long the flue gas temperature B8 can be
beyond permitted limits compared to the boiler temperature B2, without activation of the error
mode “Loss of flame – operation“.
This parameter can be found only in the configuration Ignition – NO.
The parameter setting is ranging from 0 – 800 s; the default value is 400 s.
The instructions for changing this parameter can be found in chapter 4.
If for any reasons (e.g. a lack of fuel in the storage tank) the boiler temperature falls below the limit
Low boiler temperature for the duration of Delay, the boiler is put out of operation and reports a
failure. During the first 30 min. of ignition this condition does not apply.
