NAVIGATOR™ DISPLAY MACHINE CONTROL — Machine On/Off control with the Navigator™ display is determined by the configuration of the Operating Type Control (OPER). Options to control the machine locally via a switch, from a local Time Schedule, or via a Carrier Comfort Network® command are offered. See Table 17. The schedules consist of 8 user-configurable occupied time periods. The control supports time schedules for local control, remote control, and ice building.
Time Schedule — With Time Schedule Operating Type control, the machine operates under a local schedule programmed by the user as long as the Enable/Off/Remote Contact switch is in the Enable or Remote Contact position (external contacts closed). To operate under this Operating Type Control (OPER) must be set to TIME SCHED (Time Schedule). Two Internal Time Schedules are available and must be field programmed. Time Schedule 1 (SCH1) is used for single set point On-Off control.
Heat/Cool Select (HC.SE) = 1 (Heating) allows the unit to operate in the heating mode only. Heat/Cool Select (HC.SE) = 3 (Heat Cool Sw) allows the unit to switch between cooling and heating based on a dry contact input (open contacts = Cool, closed contacts = Heat). Use of the Heat/Cool switch option requires field installed wiring to Main Base Board input channel 14. Refer to 30XW wiring diagram in Service Test section. Heat/Cool Select can also be forced from communications (CCN point name HC_SEL).
