8.7 - Control point
The control point represents the water temperature that
the unit must produce. The required capacity can be
decreased depending on the unit load operating
conditions.
Control point = Active se Reset
The control point is calculated based on the active setpoint
and the reset calculation. The forced value can be used
instead of any other setpoint calculation only when the
unit is in the Network operating type.
To verify the control point
1. Navigate to the Main menu.
2. Select
General Parameters
(GENUNIT).
3. Verify
Control Point
[CTRL_PNT].
Control Point [CTRL_PNT]
-20.0 to 67.0°C

8.7.1 - Active setpoint
Two setpoints can be selected, where the first setpoint is
used during occupied periods, whereas the second one is
used during unoccupied periods.
Depending on the current operation type, the active

the user interface, with the volt-free user contacts, with
network commands (CCN or BACnet) or automatically
with the setpoint time schedule (schedule 2).

depending on the control operating type (Local, Remote
or Network) and the following parameters:
•
