OPERATING MODE
UNIT START-UP
To turn the unit on or off, hold the ON/OFF switch down for a few seconds. When the
unit is on, the “ON” message is displayed; when the unit is off, the “OFF” message is
displayed.
It is also possible to access the different menus when the unit is in the “OFF” mode.
It is possible to check the ON/OFF condition at a distance, using a remote device (see
the ELECTRICAL CONNECTIONS chapter).

COOLING SET-POINT
The setting is performed on the OUTLET temperature.
The themoregulator acts, maintaining the exiting fluid temperature as near to the COOLING SET POINT as possible.
Therefore, it takes away steps of power when the outlet water temperature decreases to the set point and adds steps of
power when the outlet temperature increases.
The themoregulator can only add one step at a time and only when the insertion scan time expires. At any other moment,
no action of step insertion can be performed.
The insertion scan time is not fixed, but varies, according to the value of the temperature difference between the water
outlet temperature and the Set point value. The higher the difference value (positive or negative), the shorter the interval
between the scan points will be.
The value of the scan time is displayed at status 6; when status 7 reaches the value of status 6 the working demand of
the compressor is activated.
SET-POINT COMPENSATIONS
The compensations aim at optimising the energetic efficiency of the unit.
To do this, the compensations dynamically modify the set-point according to some variables. For example, in the
summertime with very low external temperatures, therefore with a reduced load, it is possible to obtain the internal
comfort even with set-points higher that the standard with a consequent higher energetic efficiency.
The
static set-point can therefore be modified dynamically with two COMPENSATIONS based on two factors external to
the unit:
•
Compensation based on the External temp. / enthalpy
• Compensation based on the Water reset (4-20 mA signal supplied by the Customer)
Optional components are necessary and, for the activation and configuration, it is necessary to modify the parameter
whose access is reserved to the assistance centres.
The menu STATUS displays the value of the compensations on the ext. temp. (status 9) and WR (status 10).
