6 - SETPOINTS SELECTION
• On the User terminal (optional):
To modify the setpoint, it is necessary to press only the or
keys.
At that time, the display will light up and the current setpoint value
from active mode (COOLING or HEATING) will appear next to the
text .
The control of the ambient temperature is carried out by starting up
the unit: compressors and/or backup component (electrical heater,
water coil, etc.).
To do so, the control compares the temperature reading of the
ambient air probe (or the return probe) with the setpoint value.
The control has two different set points: one for operation in
COOLING mode (summer) and another for operation in HEATING
mode (winter).
The selection of the setpoint can be carried out:
• On the Graphic terminal:
From the MAIN MENU, in the group C. SETPOINT.
On the last screen of this group, it is possible to display the limits of
setpoint for the supply temperature in COOLING mode (summer)
and HEATING mode (winter):
- In COOLING mode (summer): to prevent excessively signifi cant
drops in the ambient temperature.
- In HEATING mode (winter): to avoids the stratifi cation of the
hot air masses.

On the fi rst screen of this group, the setpoints of temperature
can be selected.
Note: if the indication “by schedule” appears on the screen, this
means that the setpoints have been set in the Scheduling.
On the next screen it is possible to modify the humidity setpoint
when its management is enabled (optional).
The third screen enables the display of the following calculations
of setpoints:
In which:
PS In COOLING mode (summer): Setpoint + Dead Zone / 2
PW In HEATING mode (winter): Setpoint + Dead Zone / 2
P Current selection of the setpoint
RS Setpoint of the electrical heaters in COOLING mode
RW Setpoint of the electrical heaters in HEATING mode
R Current selection of the setpoint for the electrical heaters
Note: The temperature control can be performed with the ambient
probe installed on the User terminal (optional).
The selection of this probe can only be done from a screen of the
Group G. GENCONFIG (protected by level 3 password).
VS Setpoint of the auxiliary hot water coil in COOLING mode
VW Setpoint of the auxiliary hot water coil in HEATING mode
V Current selection of the setpoint for the auxiliary coil
FV Setpoint of free-cooling in COOLING mode
FI Setpoint of free-cooling in HEATING mode
F Current selection of the setpoint for the free-cooling
When the unit includes the option of zoning up to 4 zones with
variation of air fl ow, the fi rst screens displayed will allow the
selection of the setpoints for each zone:
Zone 1 S01zn

Summer 25.5ßC
Winter 22.0ßC
With the air zoning, the control use the minimum setpoint in
COOLING mode and the maximum setpoint in HEATING mode,
among all the setpoints in the 4 zones. The S01 screen displays
these setpoints and their value cannot be changed.
Note: the optional air zoning can be selected on a screen of the
group G. GENCONFIG = a. Unit Confi g. of the TECHNICAL
MENU (password protected).
