C7000 INSTRUCTIONS FOR A/C UNITS
Here the measured values of the refrigerant circuits 1 and 2 are displayed.
1. Condensation pressure  used for G valve, HP management
2. Hotgas temperature
3. Evaporation pressure  used for LP management
4. Suction gas temperature
5. Suction gas pressure
Here the temperature of a freely adjustable sensor is shown.
This value does not influence the control and is only displayed for information.
The other values are only relevant for the chiller.
This menu is valid for units with enabled DFC² control. For historical reasons
the DFC² control is still designated by "AE-control" in this menu.
In the top line the operation mode (freeze protection, free cooling, mix mode,
summer mode) of the DFC² control is displayed. In the lower line the reason
for which summer mode has been forced is indicated. This can happen when
certain alarms have been released or when a digital input is set. The summer
operation which has not been caused by alarms but by the excess of the outsi-
de temperature limit, is not indicated here.
You find background information to the values displayed here in chapter 6.13.
