7.6 - Control point
The control point represents the water temperature that the
unit must produce. It enables to decrease the required
capacity 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.
7.6.1 - Active setpoint
Two setpoints can be selected. Depending on the current
operation type, the active setpoint can be selected manually
in the Main menu (GENUNIT – General Parameters), with
the volt-free user contacts, with network commands (CCN
or BACnet) or automatically with the setpoint time schedule
(schedule 2).
