Option 20.0 - Profile mapping default (0 – 1)*
Option 20.1 - 20.7 Profile mapping (1 – 7)*
If option parameter 20.0 is set to 0, the profile mappings will assume default values. In this case, the
profile 1 input selects fuel 1, profile 2 input selects fuel 2 and profile 4 input selects fuel 3.
If option parameter 20.0 is set to 1, it is possible to determine which fuels are to be fired when a
given profile is selected. Refer to the table on the following page for details.
For example, if fuels 2 and 3 are to be fired when profile 2 is selected, set option parameter 20.2 to 6.
Option 21.0 - Default air drive select (0 / 1)*
Options 21.1 to 21.7 - Air drive select (0 / 1) *
It is possible to prevent selected air drives from being used for each profile. Option 21.0 specifies
whether this is the case.
0
- All mapped air drives will be used for every profile.
1
- It is possible to stop air damper 2, air damper 3 and air damper 4 from being used for
each profile by using option parameters 21.1 to 21.7.
Option parameters 21.1 to 21.7 choose if certain air dampers will be used for profiles 1 to 7. The
parameters may be set to the following values (provided that option 21.0 = 1):
0
- All air drives will be used except air dampers 2, 3 and 4.
1
- All air drives will be used except air dampers 3 and 4.
2
- All air drives will be used except air dampers 2 and 4.
3
- All air drives will be used except air damper 4.
4
- All air drives will be used except air dampers 2 and 3.
5
- All air drives will be used except air damper 3.
6
- All air drives will be used except air damper 2.
7
- All air drives will be used.
For example, it is possible to set up the system so that air damper 2 is not used for profile 3 by setting
option parameter 21.3 to 6. See section xxx.
Option 22.1 - Inverter control accuracy (0 / 1)*
This parameter affects all inverters connected to the unit.
0
- Low accuracy (normal setting). Control will be performed to within approximately
±0.45Hz for a 0-60Hz system.
1
- High accuracy. Control will be performed to within approximately ±0.15Hz for a 0-
60Hz system.
Note: When using the high accuracy setting, the unit may have difficulty with controlling the speed
of the inverter. If this occurs, use the low accuracy setting for reliable operation.
