Operation mode
1: Modulating – ICM, ICMTS & CVE positioning according to Analog Input (see
¡03
)
2: ON/OFF - ICM only. Operating the ICM valve like an ON/OFF solenoid valve
controlled via Digital Input. See also
¡09
.
3: Neutralzone / 3 point control - ICM only. Increase/Decrease Opening Degree by
Digital Input. See fig. 9

Speed can be decreased. Max. speed is 100 % - Not active in manual operation (
¡01
= 2)
For CVE the speed should not exceed 50 (factory setting)
If
¡26
= 1 - 3 then factory setting =100
If
¡26
= 4 - 10 then factory setting =50
If the valve is opening and (
¡04
< = 33) or the valve is closing and (
¡14
< = 33)
=> Low is displayed.
If the valve is opening and (33 < If
¡04
< = 66) or the valve is closing and (33 < If
¡14
< = 66)
=> Med is displayed.
If the valve is opening and (
¡04

When
¡02
= 1
0: Increasing Analog Input signal => Increasing ICM Opening Degree
1: Increasing Analog Input signal => Decreasing ICM Opening Degree
When
¡02
= 3
0: DI1 = ON, DI2 = OFF => Increasing valve Opening Degree.
DI1 = OFF, DI2 = ON => Decreasing valve Opening Degree
DI1 = DI2 = OFF
=> ICAD/ICM maintain current position
DI1 = DI2 = ON
=> ICAD/ICM maintain current position
1: DI1 = ON, DI2 = OFF => Decreasing ICM Opening Degree
DI1 = OFF, DI2 = ON => Increasing ICM Opening Degree
DI1 = DI2 = OFF
=> ICAD/ICM maintain current position
DI1 = DI2 = ON
=> ICAD/ICM maintain current position
