6 - STANDARD CONTROL OPERATIONS AND OPTIONS
6.6.1 - Active setpoint
Two setpoints can be selected when the unit is in Heating mode,
and three setpoints can be selected when the unit is in Cooling
mode. The first cooling/heating setpoint is normally used during
occupied periods and the second cooling/heating setpoint is used
during unoccupied periods, whereas the third cooling setpoint is
used for ice storage (ice configuration and EMM SIOB/CIOB
required).

Depending on the current operation type (local/remote/network),
the active setpoint can be selected manually in the Main menu
(Heat/Cool Select, GENUNIT) in Local mode, with the volt-free
user contacts in Remote mode (see also section 3.8), with network
commands in Network mode (CCN, BACnet, Modbus) 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: Heat/Cool select
(HC_SEL, GENUNIT menu).
■ Setpoint selected via the SmartVu
the selection of the active setpoint if the unit is in the Local
operating type (SP_SEL, GENUNIT menu)
■ Remote setpoint contacts:
- Ice configuration from the user configuration menu
(GENCONF, Ice_cnfg must be set to "yes").
- Ice done contact from EMM (SIOB/CIOB EMM board,
DI4_ICE_SW, by default set to "closed").
- Dual setpoint switch status (spt_sw).
■ Schedule 2 status: Schedule for setpoint selection
(GENUNIT, SP_OCC set to "yes" or "no").
