C7000 INSTRUCTIONS fOR a/C UNITS
Standby units
In the menus Z0 or Z2a you can put the unit in standby by setting the
parameter in the third line "1".
The existence of standby units in a zone increase the air conditioning
operating security and provides the possibility to replace defective
units by standby units.
Selection of the supply air pressure value
In the fifth line of menu Z2a you can select the supply air pressure value, which serve as measure value for the
comparison with the set value.
The following values can be set:
1. unit - each A/C unit calculates a fan speed change according to its own measuring value. Never-
theless, a speed equalization within the zone is carried out. Because of the speed equaliza-
tion within the zone, this setting ist not useful.
2. average - an average value is calculated of the measured supply air pressure values of all units. The
fan speed of all units is controlled according to the comparison between average value and
setpoint.
3. min - the fan speed of all units is increased or reduced, until the smallest measured supply air pres-
sure in the zone has reached the setpoint.
4. max - the fan speed of all units is increased or reduced, until the biggest measured supply air pres-
sure in the zone has reached the setpoint.
