PRESENT COOLING SET-POINT
The COMPENSATED set-point, which keeps the compensations into account, is identified as the PRESENT set-point
and it is displayed on the main display and at status n° 2.
MAINTENANCE SET POINT
It can be used to maintain the installation inside the working limits, even if the unit is deactivated.
The MAINTENANCE Set Point checks the water temperature when the unit is put on OFF or Stand-by.
To do this, it periodically activates the circulation pump, tests the water temperature and even activates one or more
compressors (the max. number of compressors which can be activated in maintenance mode can be determinate by par.
27, (access reserved to the assistance centres).
SECOND SET-POINT
The secondary set point is activated by remote authorization (see the ELECTRICAL CONNECTIONS chapter).
It is possible to limit the minimum power which can be delivered during the time in which the secondary set point is
activated by configuring the 276 MinPot2Set parameter (access reserved to the assistance centres).
DEMAND LIMIT – POWER LIMIT
The function limits the electric power absorbed by the unit, according to the external 0-10Vcc or 4-20mA signal supplied
by the customer.
The higher the signal is, the lower the number of available compressors will be to satisfy the thermal need.
On the STATUS menu, n° 22, the external signal of the DEMAND LIMIT is shown.
For the activation and configuration, it is necessary to modify the parameters with access reserved to the assistance
centres.
TIMETABLES
The system is factory equipped with a clock function, found on the board.
By activating the timetables, it is possible to set up to 6 events for each day of the week.
If there is also a remote keyboard, the operations relative to the time and the date must be repeated on both keyboards,
so that the two clocks (which are different) are synchronized.
