C7000 INSTRUCTIONS fOR a/C UNITS
The corresponding commands:
Components/Cooling
ICC
In the first line you can add an integrated cooling circuit (ICC) to the configura-
tion by entering "1". With "0" you disable the ICC although all settings concer-
ning the ICC are kept.
➊
The ICC control unit communicates with the C7000 by the RS485 component
bus. The precondition for this is the identification by a global address.
In the second line you can set a global address for the ICC.
➋
In the third line the compressor model is displayed.
In the following lines you can set the P-factor
➌, the I-factor ➍ and the D-factor
➎ for specifying the control characteristics. For return air control a big P-factor
and a small I-factor is recommended, for supply air control a small P-factor and
a big I-factor instead.
In the seventh line you can adjust the start temperature
➏ for the ICC as positi-
ve offset to the temperature setpoint.
The compressor is switched off, when the temperature setpoint is passed
under and the speed is equal to minimum speed.
In the last line you can adjust the hysteresis
➐, which is decisive for the com-
pressor characteristics after the start phase (3 min.) and after ceasing of dehu-
midification request. See detailed description of start phase below.
Alarm parameters availability alarm in the first line:
- common alarm release ➀a - alarm priority ➀b
Alarm parameters for all 18 ICC alarms in the second line:
- common alarm release ➁a - alarm priority ➁b
Alarm parameters for the low pressure alarm in the third line:
- common alarm release ➂a - alarm priority ➂b
