The following table summarises the possible selections depending on the control types (local, remote or CCN) and the following parameters:

- Setpoint select in local control: item #12 of the Infor- mation menu permits selection of the active setpoint, if the unit is in local operating type.

-Heating/cooling operating mode

-Control contacts: status of control contacts 5 and 6 (dual- circuit units only). These contacts are only active if the unit is in remote control operating type. See section 3.6.6.

-Control contact 3: status of control contact 3 (single- circuit units only). See section 3.6.4.

-Contol contact 3 selection: this selection, only used for single-circuit units, indicates if contact 3 is used for dual setpoint control or for demand limit control (see User Configuration menu).

-Schedule 2 status: schedule for setpoint selection. See section 4.3.11.6.
