About the meaning and settings of the cooling priority Config/Values/Miscellaneous/
Cooling priority.
You can set a unit start delay ➋ in the second line. Different start delays for different
units prevents the most current consuming components starting simultaneously and
prevents the power supply of the building becoming overloaded.
Using the parameter in the third line, you can implement a change-over between both
CW valves. The parameter in the fourth line indicates the state of the change-over.
The "OTE" parameter ➎ in the fifth line is customer specific; for normal units the setting
is "STULZ". This parameter is set to “OTE” for activation of the OTE software.
Via parameter ➏ in the sixth line, you can determine whether the unit may be started
by a remote on/off signal. (0 = not possible, 1 = possible, all other stop causes (timer,
BMS, local stop, sequencing) are deleted. The remote on/off signal has priority).
Via the parameter ➐ in the last line, you can determine whether the unit starts auto-
matically during a power supply return after a phase failure. (0 = not possible, the unit
has to be restarted locally with this setting, 1 = possible).
Values
Miscellaneous/Cooling priority
The cooling priority ➊ determines which system has priority in units with two different
cooling systems (dual-fluid units). The mixed mode, CW, DX (EC tower) parameters are
possible for EC towers.
Mixed mode means that the system automatically chooses between cooling priority CW
and DX (EC tower).
Note on the mixed mode parameter:
The mixed mode parameter is activated as standard for the EC tower. Because the CW
setting is not permitted for the EC tower, the compressor cooling (DX) has priority in
mixed mode.
CW means that the cold water cooling has priority for ACW/GCW units.
The CW setting is not permissible for the EC tower.
DX (EC tower) means that the compressor cooling has priority for ACW/GCW units.
