Carrier SmartView - Control Point

6.7 - 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 setpoint + 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.
6.7.1 - Active setpoint
Two setpoints can be selected. Depending on the current operation
type, the active setpoint can be selected manually via 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).
The following tables summarise possible selections depending on
the control operating type (Local, Remote or Network) and the
following parameters:
■ Heating or Cooling operating mode [hc_sel]: Heat/Cool
select (GENUNIT menu).
■ Setpoint selection [sp_sel]: Setpoint select permits selection
of the active setpoint if the unit is in the Local operating type
(GENUNIT menu).
■ Setpoint switch status [SETP_SW]: Remote Setpoint Switch
(INPUTS menu).
■ Schedule 2 status [SP_OCC]: Schedule for setpoint selection.
