Description of the window ’Parameter of the CO controller - behaviour during optimisa-
tion’
NOTICE
Special situation: P 202 (low fire) > P 203 (high fire). In this case, the CO controller is only
activated outside the parameter set firing rate values.
1 CO controller type
0 = OFF
1 = ON (default)
2 Smallest permissible O

value/tolerance time during monitoring
Smallest permissible O
2
value (1/10 %) until the CO controller is switched off. If the
O
2
value remains below this parameter set limit (P 204) for longer than the time set in
P 205, the CO control switches off.
3 Low fire
Enter the firing rate value at which CO control is activated. The entry is made in digit.
Factory setting: 000
High fire
Enter the firing rate value at which CO control is deactivated. in digit.
Factory setting: 999
